FibroScan results estimate liver stiffness in kPa and liver fat with a CAP score; they do not diagnose fibrosis or cirrhosis alone. As of September 28, 2026, the most useful report combines the number, scan quality, fasting status, liver blood tests, and the reason you were scanned.
- Liver stiffness measurement below 8 kPa usually makes advanced fibrosis unlikely in metabolic liver disease when the scan is reliable.
- FibroScan kPa score of 8-12 kPa is an indeterminate zone that commonly needs blood-test context or repeat assessment.
- Higher stiffness above 12-15 kPa raises concern for advanced fibrosis or cirrhosis, but congestion, hepatitis, cholestasis, and meals can also elevate it.
- CAP score meaning relates to liver fat, not scar tissue; roughly 238, 260, and 290 dB/m are commonly used research thresholds for increasing steatosis.
- Jejum for at least 3 hours before transient elastography reduces meal-related false elevation of liver stiffness.
- Reliable scans usually include at least 10 valid readings and an IQR/median ratio of 30% or less.
- revisão urgente is warranted for jaundice, confusion, vomiting blood, black stools, or abdominal swelling, regardless of the FibroScan number.
- Specialist follow-up is more appropriate than self-diagnosis when stiffness is 8 kPa or higher, platelets are low, or liver enzymes remain abnormal.
What the Two Main Numbers on a FibroScan Report Measure
FibroScan results usually show two different measurements: liver stiffness in kilopascals (kPa) and fat attenuation in decibels per metre (dB/m). A higher kPa value can reflect fibrosis, but it can also rise temporarily from a recent meal, active hepatitis, bile blockage, or fluid pressure around the liver.
Liver stiffness measurement uses vibration-controlled transient elastography: a small mechanical pulse travels through the liver, and the device estimates how quickly that wave moves. Stiffer tissue transmits the wave faster. In my clinic, the common mistake is treating a 9.5 kPa result as a diagnosis rather than a probability signal that must be checked against the person's cause of liver disease.
CAP, or controlled attenuation parameter, estimates how much the ultrasound signal weakens as it passes through the liver. CAP is reported in dB/m, typically on a scale of about 100-400 dB/m, and primarily reflects steatosis. A high CAP score does not prove steatohepatitis, and a low CAP score does not rule out fibrosis from alcohol, viral hepatitis, autoimmune disease, or iron overload.
Kantesti é um Analisador de teste de sangue de IA that places liver enzymes, platelets, glucose, lipids, and iron markers beside imaging results rather than reading either in isolation. That distinction matters: a 7.2 kPa result with normal platelets and normal bilirubin means something quite different from 7.2 kPa with falling platelets and an elevated INR. Start with the cálculo FIB-4 when you have the required laboratory values.
Why one number cannot name the disease
FibroScan does not identify the cause of stiffness. A person with heart failure, acute alcohol-related hepatitis, or an obstructed bile duct can have a kPa value in a range otherwise associated with substantial fibrosis. The clinical question is therefore not “What stage am I?” but “Is this result credible, persistent, and consistent with my wider liver assessment?”
How to Read a FibroScan kPa Score Without Overcalling Fibrosis
A FibroScan kPa score measures resistance to a shear wave, not scar tissue directly. In many adults with metabolic dysfunction-associated steatotic liver disease, a reliable value below 8 kPa has a good negative predictive value for advanced fibrosis.
The kPa scale is not linear in clinical meaning. A change from 5 to 7 kPa may reflect ordinary biological or technical variation, whereas a persistent shift from 9 to 15 kPa is more concerning—provided the same probe, preparation, and disease context apply. EASL guidance treats liver stiffness below 8 kPa as useful for ruling out compensated advanced chronic liver disease in several common settings (EASL, 2021).
Different conditions need different cutoffs. In untreated chronic hepatitis C, values around 7-8 kPa have often been used as possible significant fibrosis thresholds, while cirrhosis thresholds commonly fall around 12-14 kPa. In metabolic liver disease, obesity and the XL probe alter performance, so transplanting a cutoff from a hepatitis study can mislead.
I have reviewed scans in lean patients with a 6.5 kPa reading and substantial metabolic risk, then in larger patients with 10 kPa readings obtained using poor-quality M-probe attempts. Neither should be casually labelled. For the broader clinical context, review our guia de teste de MASLD.
Why the unit is kPa
A kilopascal is a pressure unit. FibroScan converts wave-propagation data into an estimate of tissue stiffness, which is why results are reported in kPa rather than a percentage of fibrosis. A liver stiffness measurement of 15 kPa is not “twice as scarred” as 7.5 kPa.
Practical Fibrosis-Risk Bands for Liver Stiffness Results
For many adults with suspected metabolic liver disease, less than 8 kPa is a low-risk band, 8-12 kPa is indeterminate, and above 12-15 kPa is a high-risk band for advanced fibrosis. These are triage bands, not universal fibrosis stages or a substitute for specialist assessment.
EASL's 2021 non-invasive test guidance uses menos de 8 kPa to help exclude compensated advanced chronic liver disease and 12-15 kPa or higher to help rule it in, depending on the underlying disease and test quality (EASL, 2021). Values around 8-12 kPa are where I most often avoid reassuring or alarming language until I see platelets, AST, ALT, bilirubin, albumin, and the scan reliability metrics.
A reliable reading of 20-25 kPa or more can raise concern for clinically significant portal hypertension, especially when platelets are below 150 × 10^9/L. It still does not diagnose varices or replace clinical examination, ultrasound, or endoscopy. The combination of a high kPa score and thrombocytopenia is more meaningful than either finding alone.
A 52-year-old endurance runner I saw had a stiffness result of 11.8 kPa after a viral illness, AST 89 IU/L, and ALT 104 IU/L. A repeat scan after recovery and appropriate fasting was 7.1 kPa. If liver enzymes remain high, use our guide to acompanhamento de ALT limítrofe rather than assuming that one scan settled the question.
CAP Score Meaning: What the dB/m Result Says About Liver Fat
A CAP score estimates liver fat, with higher dB/m values generally indicating more steatosis. It does not measure fibrosis, liver-cell injury, or whether fat is causing progressive disease.
Research thresholds often place mild steatosis near 238 dB/m, moderate steatosis near 260 dB/m, and more marked steatosis near 290 dB/m. Karlas and colleagues' individual-patient meta-analysis found useful CAP cutoffs, but also showed substantial overlap between categories (Karlas et al., 2017). A score of 275 dB/m is therefore an estimate, not a precise liver-fat percentage.
CAP can run higher with greater body mass, diabetes, and use of the XL probe; probe-specific reference ranges are not perfectly interchangeable. The reading also has less clarity at the individual level than many reports imply. I tell patients that CAP is best used to monitor direction over time under comparable conditions, not to chase a single “ideal” dB/m target.
Fatty liver often travels with triglyceride elevation, glucose dysregulation, and high fasting insulin. Our review of fasting insulin signals explains why insulin resistance can matter even when an HbA1c is not yet in the diabetes range.
CAP is not a severity score for liver damage
A CAP score of 320 dB/m may reflect substantial fat while stiffness remains 5.5 kPa, which is reassuring about current advanced fibrosis risk but not a free pass. Conversely, a CAP score below 238 dB/m can coexist with advanced fibrosis from hepatitis C, alcohol exposure, autoimmune hepatitis, or previous steatotic injury.
Why Fasting Changes FibroScan Results and How Long to Fast
Fasting for at least 3 hours before FibroScan is the usual practical standard because eating can temporarily increase liver stiffness. Water is normally acceptable, but follow the testing centre's instructions if medication timing or diabetes management is involved.
After a meal, blood flow through the portal circulation increases and can push stiffness readings upward for roughly 1.5-3 hours. The effect may be clinically relevant in people near an 8 or 12 kPa decision boundary. This is one reason a non-fasting 9.0 kPa result should not automatically trigger a fibrosis label.
Avoiding a heavy meal is not the same as fasting. Most centres ask for no food or caloric drinks for 3 horas, and some use longer intervals. I also prefer patients avoid vigorous exercise on the day of the scan when possible; the evidence is less settled than for food, but it removes one avoidable source of physiological noise.
If your scan and routine blood draw are planned together, preparation differs between tests. Our guia de jejum para exame de sangue covers supplements, coffee, and medication questions that can affect a same-day laboratory panel.
Do not stop prescribed medicines without advice
Diabetes medicines, blood-pressure medicines, and essential therapies should not be skipped simply to prepare for elastography. A person using insulin or a sulfonylurea may need an individual fasting plan to avoid hypoglycaemia. Call the scanning unit beforehand rather than making a last-minute medication change.
How to Tell Whether a FibroScan Reading Is Reliable
A credible FibroScan report usually records at least 10 valid measurements and an interquartile-range-to-median ratio, often called IQR/Med. An IQR/Med of 30% or less is commonly considered acceptable when the median stiffness is in the clinically important range.
The median is the central stiffness value from repeated acquisitions; the IQR shows how widely those individual readings scattered. A median of 10.0 kPa with an IQR of 1.5 kPa is generally more persuasive than the same median with an IQR of 5 kPa. In practical terms, a noisy scan is not rescued by a dramatic-looking final number.
The M probe is commonly used in standard body habitus, while the XL probe improves feasibility when the skin-to-liver distance is greater. Do not directly compare an old M-probe value with a new XL-probe value as though they were identical instruments. The report should state the probe type, fasting status, and whether the operator obtained an adequate number of valid shots.
Kantesti é um serviço de interpretação de testes do laboratório de IA that can organise the relevant liver-panel and platelet context, but it does not replace the technical quality statement from the scan provider. Our abordagem de validação clínica treats low-quality source data as a reason for caution, not a reason to manufacture certainty.
The often-missed reliability clue
A report can look normal at first glance while being technically limited. Ask for the median kPa, CAP, IQR/Med, number of valid measurements, success rate if supplied, and probe type. Those five details make a repeat result far easier for a hepatology team to interpret.
Conditions That Raise kPa Without Permanent Liver Scarring
Acute liver injury, bile obstruction, venous congestion, recent meals, and heavy alcohol exposure can raise a FibroScan kPa score without representing fixed fibrosis. These reversible causes are particularly relevant when the stiffness result and the rest of the clinical picture disagree.
ALT or AST values more than five times the laboratory upper limit of normal make stiffness harder to interpret because active hepatocyte injury can increase tissue rigidity. For example, an ALT of 450 IU/L during acute viral hepatitis is a poor moment to stage chronic fibrosis by elastography. Repeat assessment after the acute process settles is usually more informative.
Cholestasis can elevate stiffness through increased biliary pressure. A person with jaundice, dark urine, pale stools, bilirubin above 50 µmol/L, or a rising alkaline phosphatase needs clinical assessment for obstruction rather than a casual fibrosis discussion. Our guide to cholestatic liver patterns explains the laboratory clues.
Right-sided heart failure and severe fluid overload can also elevate liver stiffness through congestion. I have seen a high kPa value fall substantially after cardiac treatment, which is why breathlessness, ankle swelling, raised jugular venous pressure, and medication changes belong in the history. A FibroScan is measuring a physical property of the liver at that moment.
Alcohol changes the interpretation
Recent sustained alcohol use can elevate GGT, AST, and liver stiffness through steatohepatitis and inflammation. A period of abstinence may improve values, but a lower repeat score does not erase prior risk. See our explanation of biomarker trends after alcohol cessation for realistic timing.
Why Fibrosis Cutoffs Change With the Cause of Liver Disease
FibroScan cutoffs vary because hepatitis B, hepatitis C, alcohol-related liver disease, MASLD, cholestatic disease, and congestive hepatopathy alter stiffness in different ways. A number that is concerning in one setting can be less specific in another.
In chronic hepatitis B, viral activity can raise ALT and stiffness, so timing relative to a flare matters. In chronic hepatitis C, published cirrhosis cutoffs often cluster around 12-14 kPa, but cure with antiviral therapy can lower stiffness through reduced inflammation before established scar tissue has fully regressed. The guia de sintomas da hepatite B explains why normal appearance does not exclude infection.
In MASLD, stiffness is interpreted alongside obesity, type 2 diabetes, hypertension, triglycerides, and FIB-4. The 2023 AASLD guidance recommends an initial FIB-4-based risk assessment in appropriate adults and secondary assessment with elastography or ELF when risk is not low (Rinella et al., 2023). This staged approach reduces unnecessary referral while missing fewer people with advanced fibrosis.
Cholestatic conditions and infiltrative disorders can produce stiffness values that overestimate fibrosis. If alkaline phosphatase is disproportionately high, autoimmune markers or imaging may matter more than a generic kPa cutoff. Patients with relevant exposure or symptoms should also understand hepatitis C testing rather than relying on elastography alone.
Pregnancy and paediatric scans need separate expertise
Pregnancy changes blood volume, liver physiology, and the differential diagnosis of abnormal liver tests; adult fibrosis bands are not a self-management tool in this situation. Children also require age-appropriate probes and specialist interpretation. A high result in either group deserves clinician-led evaluation.
Blood Tests That Make FibroScan Results More Useful
Platelets, AST, ALT, bilirubin, albumin, INR, glucose, lipids, ferritin, and viral hepatitis tests can materially change the meaning of a FibroScan result. A kPa value becomes safer to interpret when it agrees with these independent markers.
Plaquetas abaixo 150 × 10^9/L, albumin below the local reference interval, bilirubin elevation, and a prolonged INR can suggest more advanced liver dysfunction or portal hypertension when paired with high stiffness. Normal ALT does not rule out advanced fibrosis; I have seen quiet enzyme panels in patients whose platelets and imaging told the more important story.
Ferritin is an acute-phase protein and can rise with metabolic inflammation, but a ferritin above 1,000 µg/L or persistently high transferrin saturation deserves a structured iron-overload assessment. This is particularly useful when CAP is low but stiffness is unexpectedly elevated. Review iron studies in context before assuming raised ferritin means iron overload.
Kantesti é um plataforma de interpretação de biomarcadores por IA that reads liver results as patterns across time, including whether platelet count, GGT, ALT, and triglycerides are moving together. The liver panel reference guide can help you bring the correct values to a GP or hepatology appointment.
A useful discrepancy pattern
High stiffness with normal CAP should prompt a search beyond fatty liver, including viral hepatitis, alcohol-related injury, congestion, cholestasis, medication injury, autoimmune disease, and iron overload. High CAP with low stiffness usually shifts the immediate focus toward cardiometabolic risk reduction and periodic fibrosis-risk reassessment.
When an Abnormal FibroScan Needs Repeat Testing or Specialist Referral
A reliable FibroScan result of 8 kPa or more commonly warrants clinician review when liver tests are abnormal, metabolic risk is present, or there is known liver disease. A value above 12-15 kPa generally merits hepatology assessment rather than watchful waiting alone.
Repeat testing is reasonable when fasting was inadequate, IQR/Med was high, ALT was acutely elevated, alcohol intake changed recently, or the result conflicts with the clinical picture. For low-risk MASLD, repeat non-invasive fibrosis assessment is often considered every 1-3 anos, with shorter intervals for type 2 diabetes or several metabolic risk factors. The exact schedule is individual.
Refer sooner if kPa is above 12-15, FIB-4 is elevated, platelets fall, bilirubin rises, or ultrasound suggests nodularity, splenomegaly, or ascites. A specialist may choose ELF testing, MR elastography, targeted imaging, or occasionally tissue examination if the answer will change management. Our ELF score guide compares one common second-line option.
Kantesti AI can flag a mismatch—such as 14 kPa with normal enzymes but platelets of 118 × 10^9/L—as a follow-up trigger rather than a diagnosis. In my experience, that is the useful role for automated interpretation: preparing better questions for the clinician, not replacing the consultation.
O que levar à consulta
Bring the complete FibroScan report, not only the kPa and CAP figures. Include the scan date, fasting duration, probe type, IQR/Med, recent illness, alcohol history, medication and supplement list, and liver tests from the previous 12 months. This often avoids an unnecessary repeat.
What Specialists Check After a High Liver Stiffness Reading
After a high liver stiffness measurement, specialists usually confirm the result, identify the cause, and assess for complications rather than immediately assigning a fibrosis stage. The work-up often includes repeat laboratory testing, abdominal ultrasound, viral serology, medication review, and fibrosis-risk calculations.
A targeted work-up may include hepatitis B surface antigen, hepatitis C antibody with RNA testing if positive, iron saturation, ferritin, autoimmune markers, immunoglobulins, alpha-1 antitrypsin testing, and coeliac testing when indicated. Not everyone needs every test. The history—family disease, alcohol, metabolic risk, medicines, and ethnicity—guides sensible selection.
If cirrhosis is suspected, clinicians may assess platelet trends, spleen size, portal-vein features, kidney function, and whether liver-cancer surveillance is indicated. Ultrasound surveillance is commonly performed at 6-month intervals for people with established cirrhosis who are appropriate candidates, but a high FibroScan alone does not automatically establish that programme.
Unexpectedly high stiffness with emphysema, family liver history, or unexplained abnormal liver tests can make alpha-1 antitrypsin testing relevant. Kantesti's guia de tecnologia de IA explains how our system presents possible follow-up themes without claiming to determine a diagnosis.
Why biopsy is now less common, not obsolete
Tissue examination is no longer required for every patient because combined blood and imaging tests classify many people well enough for care decisions. It remains useful when non-invasive tests disagree, an alternative diagnosis is plausible, or treatment eligibility depends on histological detail.
What Can Improve CAP, Liver Enzymes, and Fibrosis Risk Over Time
Weight loss, regular physical activity, diabetes control, and avoiding alcohol when liver disease is present can reduce liver fat and improve liver risk markers. A falling CAP or ALT is encouraging, but it does not by itself prove that fibrosis has reversed.
For many people with MASLD, sustained loss of 5% do peso corporal é mais provável que melhore a esteato-hepatite e as medidas relacionadas com a fibrose; a resposta precisa varia com o tratamento da diabetes, a atividade física, o sono, a genética e o álcool. A alimentação de estilo mediterrânico, o treino de resistência, a atividade aeróbica e o tratamento baseado em evidências da diabetes ou da obesidade devem pertencer ao mesmo plano, não a campos concorrentes. 7-10% is more often associated with improvement in steatohepatitis and fibrosis-related outcomes. Response varies: a person starting at 100 kg may see metabolic benefit from 5 kg lost, but their individual treatment plan should account for nutrition, medicines, and muscle mass.
Busque pelo menos 150 minutos por semana of moderate aerobic activity plus resistance work where safe. Exercise can reduce liver fat even without major weight loss. Avoid “liver detox” supplements; concentrated green-tea extract, anabolic products, and multi-ingredient weight-loss remedies are recurrent causes of drug-induced liver injury.
Food choices work best when they are specific and sustainable: fibre-rich plants, minimally processed protein, unsweetened drinks, and fewer refined carbohydrates are reasonable starting points. Our evidence-based liver-supportive food guide separates practical dietary measures from detox marketing.
Do not use a scan to punish yourself
CAP and kPa are clinical measurements, not report cards. I have had patients dramatically restrict food before a scan in an effort to improve the number; that only makes serial comparison less useful. Use the same preparation each time and focus on changes that remain workable after the appointment.
Symptoms That Need Urgent Care Regardless of Your FibroScan Number
Jaundice, confusion, vomiting blood, black tarry stools, new abdominal swelling, severe drowsiness, or fever with upper abdominal pain require urgent medical assessment regardless of FibroScan results. Elastography does not assess acute liver failure, gastrointestinal bleeding, infection, or bile-duct obstruction safely enough to delay care.
New confusion, sleep-wake reversal, or marked drowsiness in someone with known liver disease can signal hepatic encephalopathy or another serious condition. Vomiting blood or passing black stools can indicate upper gastrointestinal bleeding. Call emergency services or seek emergency care rather than waiting for a repeat scan or online interpretation.
Yellow eyes with dark urine, pale stools, fever, and right-upper abdominal pain may indicate cholestasis, gallbladder disease, or acute hepatitis. Bilirubin can rise quickly in these settings, while kPa may be temporarily inflated by biliary pressure. Our guide to quando a bilirrubina requer atendimento de emergência cobre o padrão de alerta.
As Chief Medical Officer, Dr. Thomas Klein advises against using any result app as emergency triage. Kantesti can preserve longitudinal records and help list relevant abnormalities, but symptoms and deterioration always outrank a reassuring older number.
Pregnancy is a special case
Itching of the palms or soles, jaundice, headache with visual changes, severe nausea, or upper abdominal pain during pregnancy needs same-day maternity assessment. Pregnancy-related liver disorders can evolve quickly, and standard FibroScan thresholds are not designed to exclude them.
How to Track FibroScan Results Safely Over Time
The best comparison is a repeat FibroScan done with the same fasting conditions, similar probe selection, and the same supporting blood tests. One isolated kPa result is less informative than a trend that remains consistent after technical and clinical confounders are checked.
Record the date, kPa, CAP, probe, IQR/Med, fasting interval, weight, alcohol exposure, recent illness, and ALT value each time. A shift from 6.4 to 7.0 kPa may be ordinary variation, while a confirmed move from 7.0 to 13.5 kPa alongside falling platelets needs prompt review. Trends only mean something when the conditions are comparable.
Kantesti AI supports longitudinal review of uploaded laboratory reports and can identify changes in enzyme, platelet, glucose, and lipid patterns across visits. Kantesti is used by people in more than 127 countries, but local laboratory ranges, access to elastography, and referral pathways still matter. Dr. Thomas Klein's practical rule is simple: preserve the original report and ask what changed physiologically before assuming fibrosis progressed.
Our doctors and clinical standards are described through the Conselho Consultivo Médico.

They are included for transparent research indexing only.
A final practical question for your clinician
Ask: “Does my kPa result agree with my platelet count, liver function, metabolic risk, ultrasound, and scan quality?” That question usually produces a more useful plan than asking for a fibrosis stage from a single number. Persistently abnormal results deserve follow-up, while a technically flawed scan deserves repetition.
Perguntas frequentes
Qual é uma pontuação normal de kPa no FibroScan?
Uma medição de rigidez hepática por FibroScan abaixo de 8 kPa é comumente considerada um resultado de menor risco para fibrose avançada em adultos com suspeita de doença hepática metabólica, quando o exame é tecnicamente confiável. Muitos adultos saudáveis têm leituras em torno de 2-7 kPa, embora não haja uma única faixa normal universal porque idade, tamanho corporal, tipo de sonda e condição hepática afetam a interpretação. Um valor abaixo de 8 kPa não exclui todas as condições hepáticas, especialmente hepatite aguda ou doença não fibrótica. O IQR/Med do relatório, o estado de jejum e os exames de sangue devem ser revisados juntamente com o número.
7 kPa no FibroScan é mau?
Um resultado confiável do FibroScan de 7 kPa é frequentemente tranquilizador porque fica abaixo do limiar de 8 kPa comumente usado para risco de fibrose avançada em muitos caminhos do MASLD. Não é automaticamente normal em todos os cenários: hepatite viral não tratada, testes hepáticos anormais ou uma contagem de plaquetas em queda podem alterar seu significado. Um resultado de 7 kPa obtido após comer ou durante uma doença aguda pode ser menos interpretável. A maioria dos pacientes deve discutir a pontuação com o médico que sabe por que o exame foi solicitado.
O que o escore CAP significa esteatose hepática?
Uma pontuação CAP de cerca de 238 dB/m ou superior pode sugerir pelo menos gordura hepática leve, enquanto limiares de pesquisa em torno de 260 dB/m e 290 dB/m são frequentemente usados para esteatose moderada e mais acentuada. A CAP é uma estimativa da atenuação ultrassonográfica em vez de uma medição direta da porcentagem de gordura hepática. O tamanho corporal, diabetes, tipo de transdutor e fatores técnicos podem alterar o resultado. Uma pontuação CAP alta não indica se a fibrose está presente, portanto, a pontuação kPa e os exames de sangue do fígado ainda são importantes.
Comer antes de um FibroScan pode fazer com que a pontuação kPa seja alta?
Sim, comer antes do FibroScan pode aumentar temporariamente a rigidez hepática porque a comida aumenta o fluxo sanguíneo portal e altera a hemodinâmica hepática. A maioria dos centros pede aos pacientes que evitem alimentos e bebidas calóricas por pelo menos 3 horas antes do exame. O efeito pode ser suficiente para importar quando o resultado está próximo das bandas de decisão de 8 kPa ou 12 kPa. A água geralmente é permitida, mas as pessoas que tomam medicamentos redutores de glicose devem confirmar seu plano de preparação com o centro de testes.
Uma pontuação FibroScan de 12 kPa significa cirrose?
Uma pontuação de FibroScan de 12 kPa não prova cirrose, mas é alta o suficiente para justificar acompanhamento clínico estruturado em muitos cenários de doença hepática. Na doença hepática metabólica, 12-15 kPa é frequentemente tratada como uma faixa de maior risco para fibrose avançada; na hepatite viral, os pontos de corte de cirrose publicados podem ser semelhantes, mas variam por estudo. Refeições recentes, inflamação hepática aguda, obstrução biliar e congestão relacionada ao coração podem aumentar a rigidez sem cirrose fixa. Um especialista pode confirmar o risco usando plaquetas, FIB-4, ELF, imagens ou elastografia por RM.
Com que frequência o FibroScan deve ser repetido?
Repeat FibroScan timing depends on the cause of liver disease and the first result, but low-risk metabolic liver disease is often reassessed every 1-3 years. People with type 2 diabetes, several metabolic risk factors, abnormal liver enzymes, or indeterminate stiffness may need earlier reassessment. A technically limited scan, non-fasting scan, or scan performed during acute illness is often repeated sooner once the confounder has resolved. Repeating under the same fasting and probe conditions makes the trend more meaningful.
