Niðurstöður FibroScan meta lifrarstífleika í kPa og lifrarfitu með CAP skori; þær greina ekki trefjamyndun eða skorpulifur eingöngu. Frá 28. september 2026 sameinar gagnlegasta skýrslan töluna, gæði skannunar, föstuástand, lifrarblóðprufur og ástæðuna fyrir því að þú varst skannaður.

- FibroScan kPa skora frá 8-12 kPa er óskýrt svæði sem oft þarf samhengi blóðprufa eða endurtekinna mats.
- Hærri stífleiki yfir 12-15 kPa vekur áhyggjur af langgengnum trefjamyndun eða skorpulifur, en stífla, lifrarbólga, gallrásartruflanir og máltíðir geta einnig hækkað hana.

Hvað aðal Tölurnar Tvær á FibroScan Skýrslu Meta
FibroScan niðurstöður sýna venjulega tvær mismunandi mælingar: lifrarstífni í kilopascal (kPa) og fituþáttun í desibel á metra (dB/m). Hærra kPa gildi getur endurspeglað þræðingar, en það getur einnig hækkað tímabundið vegna nýlegrar máltíðar, lifrarbólgu í virku ástandi, gallteppu eða vökvaþrýstings í kringum lifur.
Mæling á lifrarstífleika notar titringsstýrða tímabundna tækni elastography: lítill vélrænn púls fer í gegnum lifur og tækið metur hversu hratt þessi bylgja hreyfist. Stífari vefur flytur bylgjuna hraðar. Á minni stofn er algeng mistök að meðhöndla 9,5 kPa niðurstöðu sem greiningu frekar en líkindamerki sem þarf að athuga með orsök lifrarsjúkdóms hjá viðkomandi.
CAP, eða stýrt þáttunarhlutfall, metur hversu mikið úthljóðmerkið veikist þegar það fer í gegnum lifur. CAP er tilkynnt í dB/m, venjulega á kvarða frá um það bil 100-400 dB/m, og endurspeglar aðallega fitusjúkdóm. Hár CAP stig sanna ekki fitulifrarbólgu, og lágt CAP stig útilokar ekki þræðingar vegna áfengis, veiru lifrarbólgu, sjálfsofnæmissjúkdóms eða járn ofhleðslu.
Kantesti er AI blóðprufugreiningartæki sem setur lifrarensím, blóðflögur, glúkósa, lípíð og járnmerki við hlið myndgreiningar niðurstaðna frekar en að lesa hvorttveggja í einangrun. Þessi greinarmunur skiptir máli: 7,2 kPa niðurstaða með eðlilegum blóðflögum og eðlilegu bilirúní manni þýðir eitthvað allt annað en 7,2 kPa með lækkandi blóðflögum og hækkuðu INR. Byrjaðu á FIB-4 útreikningur þegar þú hefur nauðsynlegar rannsóknarniðurstöður.
Hvers vegna eitt númer getur ekki nefnt sjúkdóminn
FibroScan auðkennir ekki orsök stífni. Maður með hjartabilun, bráða áfengistengda lifrarbólgu eða stífluðu gallrás getur haft kPa gildi á kvarða sem annars tengist umtalsverðum þræðingum. Klíníska spurningin er því ekki “Hvaða stig er ég?” heldur “Eru þessar niðurstöður trúverðugar, þrálátar og í samræmi við víðtækari lifrarefnisgreiningu mína?”
Hvernig Á Að Lesa FibroScan kPa Skora Án Ofmatningar Á Trefjamyndun
FibroScan kPa stig mælir mótstöðu við skurðbylgju, ekki beint örvef. Hjá mörgum fullorðnum með efnaskipta-tengdan fitulifrar, hefur áreiðanlegt gildi undir 8 kPa gott neikvætt spámerki fyrir langt gengið þræðingar.
kPa kvarðinn er ekki línulegur í klínískri merkingu. Breyting frá 5 til 7 kPa getur endurspeglað venjulega líffræðilega eða tæknilega breytileika, en þrálát breyting frá 9 til 15 kPa er meira áhyggjuefni - að því gefnu að sama rannsaka, undirbúningur og sjúkdómsástand gildi. EASL leiðbeiningar líta á lifrarstífni undir 8 kPa sem gagnlegt til að útiloka skerta langvarandi lifrarsjúkdóm á mörgum algengum sviðum (EASL, 2021).
Mismunandi sjúkdómar þurfa mismunandi viðmiðunargildi. Í ónæmdu langvinnu lifrarbólgu C hafa gildi um 7-8 kPa oft verið notuð sem möguleg þröskuldur fyrir marktækri þræðingu, á meðan þröskuldur fyrir skorpulifur eru oft um 12-14 kPa. Í efnaskipta lifrarsjúkdómum hafa offita og XL rannsaka áhrif á frammistöðu, svo að flytja þröskuld úr lifrarbólgu rannsókn getur verið villandi.
Ég hef skoðað skannar hjá horaðum sjúklingum með 6,5 kPa mælingu og umtalsverða efnaskiptaáhættu, síðan hjá stærri sjúklingum með 10 kPa mælingar fengnar með lélegum M-rannsaka tilraunum. Hvorki ætti að flokka hversdagslega. Fyrir breiðari klíníska samhengi, skoðaðu okkar MASLD prófunarleiðbeiningar.
Hvers vegna einingin er kPa
Kilopascal er þrýstieining. FibroScan breytir bylgjuflutningsgögnum í mat á stífni vefjar, þess vegna eru niðurstöður tilkynntar í kPa frekar en hlutfall af þræðingu. Lifrarstífni mæling á 15 kPa er ekki “tvöfalt örvefjaðri” en 7,5 kPa.
Hagnýtar Trefjamyndun-Áhættubönd Fyrir Lifrarstífleika Niðurstöður
Fyrir marga fullorðna með grun um efnaskipta lifrarsjúkdóm, er minna en 8 kPa lágt áhættusvæði, 8-12 kPa er óákveðið, og yfir 12-15 kPa er hááhættusvæði fyrir langt gengið þræðingar. Þetta eru flokkunarviðmið, ekki almenn stig þræðingar eða staðgengill fyrir sérfræðilegt mat.
EASL's 2021 non-invasive test guidance uses minna en 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 jaðarlág ALT eftirfylgni rather than assuming that one scan settled the question.
CAP Skora Merking: Hvað dB/m Niðurstaða Segir Um Lifrarfitu
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.
Af hverju Fasta Breyter FibroScan Niðurstöður og Hversu Lengi Á Að Fasta
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 klukkustundir, 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 leiðarvísir um fastandi blóðpróf 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.
Hvernig Á Að Vita Hvort FibroScan Lestur Er Áreiðanlegur
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 er þjónustu fyrir túlkun á rannsóknarprófum með gervigreind that can organise the relevant liver-panel and platelet context, but it does not replace the technical quality statement from the scan provider. Our klíníska staðfestingarleið 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.
Ákveðnar Aðstæður Sem Hækka kPa Án Varandi Lifrarhrúðrar
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 µmól/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.
Af hverju Skurðamörk Trefjamyndunar Breyta Með Orsök Lifrarsjúkdóms
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 einkennavísir lifrarbólgu 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.
Blóðprufur Sem Gera FibroScan Niðurstöður Gagnlegri
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.
Blóðflögur undir 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 er AI lífmerkjatúlkunarvettvangur 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.
Hvenær Óeðlileg FibroScan Þarf Endurtekin Próf eða Tilvísun Sérfræðings
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 ár, 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.
Hvað á að taka með í viðtalið
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.
Hvað Sérfræðingar Athuga Eftir Háværa Lifrarstífleika Lestur
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 leiðarvísir fyrir gervigreindartækni 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.
Hvað Getur Bætt CAP, Lifrarensím og Trefjamyndun Áhættu Yfir Tímann
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% af líkamsþyngd bætir lifrarfitu, á meðan 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.
Markmið á að minnsta kosti 150 mínútur á viku 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.
Einkenni Sem Þurfa Bráða Umönnun Burtséð Frá FibroScan Tölunni Þinni
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 hvenær bilirúbín þarfnast bráðrar meðferðar fjallar um viðvörunar mynstrið.
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.
Hvernig Á Að Fylgjast Með FibroScan Niðurstöðum Öruggt Yfir Tímann
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 Læknisfræðileg ráðgjafarnefnd. For readers who want supplementary lab-interpretation publications, the two DOI records below concern iron and coagulation testing; they do ekki validate FibroScan or replace liver-specific guidelines. 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.

Hún er ekki sjálfkrafa eðlileg í öllum tilvikum: ómeðhöndlað veiruheilkenni lifrarbólgu, óeðlilegar lifrarprófanir eða lækkandi blóðflagnafjöldi geta breytt merkingu hennar. 7 kPa niðurstaða sem fæst eftir að hafa borðað eða á meðan á bráðri sjúkdómi stendur getur verið síður túlkanleg. Flestir sjúklingar ættu að ræða niðurstöðuna við lækninn sem veitir fyrirskipað var.
Hvað þýðir CAP skorið fyrir fitulifur?
A CAP skori um 238 dB/m eða hærri getur bent til að minnsta kosti vægrar lifrarfitu, en rannsóknarþröskuldar í kringum 260 dB/m og 290 dB/m eru oft notaðir fyrir miðlungs og meiri fitusjúkdóm. CAP er mat á úthljóðs dempun frekar en bein mæling á lifrarfituprósentu. Stærð líkamans, sykursýki, gerð rannsaka og tæknilegir þættir geta haft áhrif á niðurstöðuna. Hár CAP skori segir ekki til um hvort bandvef sé til staðar, svo kPa skori og lifrarblóðpróf skipta enn máli.
Getur það að borða fyrir FibroScan skilið kPa gildi hátt?
Já, að borða fyrir FibroScan getur tímabundið aukið lifrarstífni þar sem matur eykur blóðflæði um lifrarportið og breytir lifrarblóðfræði. Flestar miðstöðvar biðja sjúklinga um að forðast mat og kaloríuríka drykki í að minnsta kosti 3 klukkustundir fyrir rannsóknina. Áhrifin geta verið nægjanleg til að skipta máli þegar niðurstaðan er nálægt 8 kPa eða 12 kPa ákvörðunarböndum. Venjulega er vatn leyft, en þeir sem taka lyf sem lækka blóðsykur ættu að staðfesta undirbúningsáætlun sína við prófunarmiðstöðina.
Þýðir FibroScan-gildið 12 kPa skorpulifur?
FibroScan mæling upp á 12 kPa sannar ekki skorpulifur, en hún er nógu há til að réttlæta skipulagða klíníska eftirfylgni í mörgum lifrarsjúkdómum. Í efnaskiptalifrarsjúkdómum er 12-15 kPa oft talið aukin áhætta fyrir langt gengið bandvefsmyndun; í lifrarbólgu af völdum veira geta birtir skorpulifrarþröskuldar verið svipaðir en eru misjafnir eftir rannsókn. Nýleg máltíð, bráð lifrarbólga, gallgangalokun og hjartatengd þrengsli geta öll aukið stífni án varanlegrar skorpulifrar. Sérfræðingur getur staðfest áhættu með blóðflögum, FIB-4, ELF, myndgreiningu eða segulómunarelastografi.
Hversu oft ætti að endurtaka FibroScan?
Endurtekin FibroScan-mæling fer eftir orsök lifrarsjúkdóms og fyrstu niðurstöðu, en efnaskiptalifrarmeðferð með litla áhættu er oft endurmetin á 1-3 ára fresti. Fólk með sykursýki af tegund 2, nokkra efnaskiptaáhættuþætti, óeðlilegt lifrarensím, eða óljósa stífleika gæti þurft að endurmeta fyrr. Tæknilega takmörkuð mæling, mæling án fastandi eða mæling í bráðri veikindum er oft endurtekin fyrr þegar ruglingurinn hefur lagast.
