Albei toetse bespeur inflammmasie in die ingewande wat deur neutrofiele gedryf word, maar kalprotektien is gewoonlik die nuttiger kwantitatiewe monitering-instrument. Die regte resultaat is een wat die volgende kliniese besluit verander – nie een wat jou met IBD merk nie.
- Kalprotektien onder 50 µg/g is oor die algemeen gerusstellend by volwassenes met vermoedelike IBS wanneer daar geen alarmkenmerke is nie.
- Laktoferrien is 'n neutrofielproteïen; baie kwantitatiewe toetse gebruik minder as 7.25 µg/g as negatief, maar laboratoriumafsnypunte wissel.
- Hoë stoelgangmerkers dui op inflammmasie in die ingewande, nie 'n spesifieke diagnose nie; infeksie, NSAID's, divertikulitis en kolorektale neoplasie kan albei verhoog.
- Grenskalprotektien van 50–150 µg/g verdien dikwels 'n herhaalmonster na 2–6 weke eerder as onmiddellike kolonoskopie.
- Kalprotektien bo 250 µg/g verhoog kommer oor aktiewe mukosale inflammasie en lei gewoonlik tot kliniese oorsig, stoelganginfeksietoetse of endoskopiebeplanning.
- Normale resultate maak aktiewe kolonies IBD minder waarskynlik, maar kan geïsoleerde Crohn se siekte van die dunderm nie betroubaar uitsluit nie.
- IBD-monitering gebruik simptome plus biomerkers, CRP, anemie-markers, beelding en endoskopie; geen stoelgangmerker diagnoseer op sigself 'n opvlamming nie.
- Dringende simptome soos swart stoelgang, aanhoudende sigbare bloed, koors, erge pyn, floute of dehidrasie benodig mediese assessering ongeag 'n markeruitslag.
Watter stoelgangmerker moet jy eers kies?
Fekale kalsulfakolties is gewoonlik die eerste keuse stoelgang inflammasie marker omdat dit wyd beskikbaar is, kwantitatief is, en die sterkste rol speel in die skeiding van waarskynlike inflammatoriese dermsiekte van funksionele derm simptome. Fekale laktoferrientoets resultate is 'n sinvolle alternatief wanneer dit die plaaslik gevalideerde toets is, maar om albei aan die begin te bestel verander selde die sorg.
Vir 'n persoon met 6 weke van los stoelgange, krampe, en geen gewigsverlies of rektale bloeding nie, sou ek oor die algemeen begin met kalsulfakolties plus geteikende infeksie toetsing eerder as kolonoskopie. 'n Uitslag onder 50 µg/g maak beduidende koloniese inflammasie minder waarskynlik, terwyl 'n duidelik verhoogde uitslag rede gee om verder te kyk. Die AGA-riglyn vir chroniese waterige diarree ondersteun kalsulfakolties of laktoferrien as siftings-toetse vir inflammatoriese toestande (Smalley et al., 2019).
Kies laktoferrien wanneer jou gastroenterologie diens dit konsekwent gebruik, wanneer die laboratorium 'n gevalideerde kwantitatiewe waarde rapporteer, of wanneer dit saam met 'n infeksie diarree werkbestelling gebundel word. Moenie dit kies omdat dit meer spesifiek klink nie: albei proteïene word vrygestel wanneer neutrofiele die derm lumen binnekom. Die praktiese kwessie is of jou klinikus die uitslag met jou vorige monsters kan vergelyk met dieselfde toets.
Kantesti is 'n KI-bloedtoetsontleder wat verwante resultate soos hemoglobien, CRP, albumien en ysterindekse langs 'n stoelgang-marker verslag plaas; dit vervang nie die stoelgang toets of 'n klinikus se diagnose nie. Indien moegheid diarree vergesel, 'n bloedtoets vir diarree kan help om dehidrasie, anemie, of elektrolietverlies te identifiseer wat dringendheid verander.
'n Nuttige vuistreël
Gebruik een gevalideerde merker eerste, herhaal dieselfde merker wanneer 'n resultaat grensgeval is of wanneer behandeling gemonitor word, en reserveer dubbele toetsing vir 'n spesifieke gastroenterologie vraag. Om die toets halfpad deur opvolging te verander, skep skynbare neigings wat eerder laboratorium geraas as biologie mag wees.
Wat fekale kalprotektien eintlik bespeur
Kalsulfakolties meet 'n kalsium- en sink-bindende proteïen wat hoofsaaklik van neutrofiele in die ingewande vrygestel word. 'n Hoër stoelgang konsentrasie weerspieël neutrofiel migrasie in die derm, wat algemeen is in aktiewe IBD, maar ook voorkom met verskeie nie-IBD toestande.
Kalsulfakolties is die S100A8/S100A9 proteïen kompleks, en dit bly relatief stabiel in stoelgang vir etlike dae by kamertemperatuur—een rede waarom dit goed werk as 'n huisversameling toets. Sy biologiese krag is lokaliteit: anders as CRP, weerspieël dit sellulêre aktiwiteit in die derm lumen eerder as 'n hele-liggaam akute-fase reaksie. 'n Normale CRP kanselleer dus nie 'n hoë kalsulfakolties uitslag nie.
In volwasse praktyk, klassifiseer laboratoriums algemeen minder as 50 µg/g as normaal en meer as 150–250 µg/g as toenemend versoenbaar met aktiewe derm inflammasie. Dit is beslissingsdrempels, nie universele biologiese grense nie. Sommige Europese dienste gebruik 100 µg/g as die verwysingsdrempel, terwyl pediateriese en toets-spesifieke verwysingsintervalle aansienlik kan verskil.
Ek het 'n 28-jarige gesien met 'n kalsulfakolties van 680 µg/g, 'n normale CRP, en uiteindelik ulseratiewe kolitis beperk tot die rektum en sigmoid kolon. Daardie patroon is nie ongewoon nie: plaaslike mukosale inflammasie kan aktief wees sonder 'n sterk sistemiese sein. Ons fecal calprotectin range guide explains why the laboratory’s own method and units should stay attached to every result.
Wat fekale laktoferrien anders bespeur
Lactoferrin detects another neutrophil-derived protein and answers nearly the same biological question as calprotectin: is there active intestinal neutrophil inflammation? It does not identify ulcerative colitis, Crohn’s disease, bacterial colitis, or another cause on its own.
Lactoferrin is an iron-binding glycoprotein stored in neutrophil secondary granules and released during activation. A positive qualitative fecal lactoferrin test is useful because it argues against uncomplicated IBS in the right clinical setting. Quantitative assays vary: one commonly used method defines a negative value as less than 7.25 µg/g, so never apply a calprotectin cutoff to a lactoferrin report.
The evidence does not show that lactoferrin is categorically superior. In a diagnostic meta-analysis, Wang and colleagues found fecal lactoferrin had pooled sensitivity of 82% and specificity of 95% for distinguishing IBD from non-IBD controls, although accuracy estimates shift with disease prevalence and study design (Wang et al., 2015). That impressive specificity still does not convert a positive result into an IBD diagnosis.
A positive lactoferrin result is especially worth discussing when diarrhoea began abruptly after travel, antibiotics, contaminated food exposure, or contact with someone unwell. In those situations, clinicians usually add pathogen testing rather than jumping straight to an IBD label. Our guide to stoel kultuurresultate covers what a negative or mixed-growth report can and cannot settle.
Hoe om afsnypunte te lees sonder om te oorreageer
A calprotectin value below 50 µg/g is usually normal for adults, 50–150 µg/g is often an indeterminate zone, and values above 250 µg/g raise concern for active inflammation. Lactoferrin uses assay-specific cutoffs, commonly a qualitative positive or a quantitative threshold near 7.25 µg/g.
The 50 µg/g calprotectin threshold is designed for sensitivity: it catches most clinically significant inflammatory disease at the cost of some false positives. The 250 µg/g threshold is more useful for specificity and for monitoring established IBD. Between them lies the frustrating middle, where medication exposure, recent gastroenteritis, age, and trajectory matter more than a single number.
A change from 72 to 94 µg/g is often less meaningful than a change from 85 to 430 µg/g, particularly if both samples were tested by the same laboratory. Stool consistency can influence extraction and biological variation is real. Dr. Thomas Klein’s practical advice is to record NSAID use, recent infection, menstrual contamination, and collection date before interpreting a modest rise.
For a disciplined approach to serial values, compare the sample date with symptoms and related labs rather than treating every flagged result as disease progression. Our bloedtoets-trendgids explains the same principle of reference change and analytic variation in laboratory medicine.
Waarom albei merkers hoog kan wees sonder IBD
Elevated stool inflammation markers occur with enteric infection, NSAID exposure, diverticulitis, colorectal neoplasia, microscopic colitis and IBD. The result confirms an inflammatory signal; it does not disclose the cause, location, duration, or severity by itself.
Non-steroidal anti-inflammatory drugs can raise fecal calprotectin, sometimes substantially, by increasing intestinal permeability and causing small mucosal injuries. Ibuprofen, naproxen and diclofenac matter; a clinician may suggest withholding them if medically safe before repeating the test. Do not stop prescribed aspirin, anticoagulants, or pain medicines without asking the prescriber first.
Acute bacterial gastroenteritis may produce calprotectin values above 500 µg/g and a positive lactoferrin, which is why a stool pathogen panel can be more informative than an urgent colonoscopy in the first days of illness. Conversely, giardiasis may cause prolonged diarrhoea with less striking neutrophilic marker elevation. The symptom timeline often carries more diagnostic weight than patients expect.
Kantesti is 'n KI-labtoets-interpretasiediens that can flag an inflammation pattern such as low hemoglobin, low albumin, thrombocytosis and raised CRP for clinician review, but those blood findings do not prove the source is intestinal. For people with blood in the stool, FIT follow-up and colonoscopy timing is a separate issue from calprotectin and should not be delayed.
Wanneer 'n normale resultaat steeds siekte kan mis
Normal calprotectin or lactoferrin makes active colonic inflammation less likely, but it cannot fully exclude Crohn’s disease, particularly mild or isolated small-bowel disease. A normal result also does not explain persistent weight loss, iron-deficiency anemia, nocturnal diarrhoea, or recurrent visible bleeding.
Small-bowel Crohn’s disease can shed less neutrophil protein into a stool sample than extensive colitis, especially when lesions are proximal or mild. This is one reason symptoms and alarm features overrule a reassuring number. The ECCO-ESGAR diagnostic guideline recommends integrating biomarkers with ileocolonoscopy and cross-sectional imaging when IBD remains clinically suspected (Maaser et al., 2019).
A 46-year-old with calprotectin of 38 µg/g, ferritin of 7 ng/mL, and progressive fatigue deserves evaluation for gastrointestinal blood loss or malabsorption even if bowel frequency is normal. In my experience, the combination of iron deficiency and unexplained symptoms is much more consequential than a single low stool marker. Read our low ferritin and gut clues for the usual next laboratory questions.
Celiac disease, bile acid diarrhoea, pancreatic insufficiency and many medication effects may cause symptoms with normal stool inflammation markers. A normal test is therefore a fork in the road toward non-inflammatory diagnoses, not a declaration that symptoms are psychological or unimportant.
Wat om te doen met 'n grensposisie kalprotektien resultaat
A borderline fecal calprotectin result of 50–150 µg/g is commonly repeated after 2–6 weeks if symptoms are stable and there are no alarm features. The repeat should use the same laboratory method and should be timed away from a recent gastrointestinal infection where possible.
Before retesting, clinicians review NSAIDs, proton-pump inhibitors, antibiotics, acute infections, strenuous endurance exercise and age-related risk. There is no universally agreed washout interval for every medicine. A pragmatic plan is often 2 weeks after an acute illness has settled, provided symptoms do not signal a need for earlier care.
If the repeat falls from 118 to 32 µg/g and symptoms settle, invasive testing may be avoidable. If it rises from 96 to 310 µg/g, the direction adds useful evidence even before an endoscopy result arrives. This is why a single borderline value should rarely trigger panic—or false reassurance.
Ons borderline calprotectin follow-up guide lays out the questions to bring to a primary-care or gastroenterology appointment. A short symptom diary with stool frequency, nighttime waking, fever and medication dates is usually more useful than obsessively checking food triggers.
Hoe klinici merkers gebruik nadat IBD gediagnoseer is
In established IBD, calprotectin is most useful for tracking objective intestinal inflammation and helping decide whether symptoms represent a flare, infection, IBS overlap, or treatment failure. Lactoferrin can also follow activity, but calprotectin has more guideline-supported thresholds for treat-to-target monitoring.
Symptoms and mucosal activity frequently diverge. A patient with ulcerative colitis may feel well while calprotectin climbs from 80 to 360 µg/g, or have urgent bowel motions from bile acid malabsorption while calprotectin remains 28 µg/g. The 2023 AGA ulcerative colitis biomarker guideline advises combining symptoms with biomarkers rather than relying on either alone (Singh et al., 2023).
For remission monitoring, many clinicians view less than 150 µg/g as reassuring, while more than 150 µg/g may warrant repeat testing, endoscopy, or treatment review depending on symptoms and prior disease behaviour. In active symptomatic ulcerative colitis, more than 250 µg/g supports ongoing inflammation. Cutoffs are guides, not instructions to alter biologic treatment without specialist input.
Kantesti AI is ’n KI-biomerkers-interpretasieplatform that organizes blood-test trends around a patient’s reported treatment dates; it cannot assess stool endoscopic severity from a number alone. Patients taking biologics should also understand which blood safety tests monitor treatment and which symptoms require prompt contact with their IBD team.
Hoe versamelingsfoute en tydsberekening resultate beïnvloed
Collection quality affects stool marker interpretation because a contaminated, delayed, or poorly sampled specimen can be rejected or produce a less reliable measurement. Most laboratories want a small stool portion placed into the supplied sterile container without toilet water or urine.
Loose stool is usually acceptable for calprotectin and lactoferrin testing; do not wait for a formed sample if diarrhoea is the clinical problem. Avoid collecting from toilet water, and tell the laboratory if the sample includes visible menstrual blood. Storage instructions vary by kit, but many allow short room-temperature transport because calprotectin is comparatively stable.
Sampling a day after a marathon, a bout of gastroenteritis, or colonoscopy bowel preparation may answer the wrong question. Endurance exercise can transiently increase gut permeability and provoke gastrointestinal symptoms. If you are an endurance athlete without red flags, consider timing collection away from a major event; our uithouvermoë-atleet laboratoriumgids explains why context changes test interpretation.
The thing is, a perfect collection does not make a nonspecific biomarker specific. A high-quality sample improves confidence in the measurement; it cannot replace the clinical history, examination, and differential diagnosis.
Watter bloedtoetse 'n stoelgangmerker nuttiger maak
A CBC, CRP, ferritin, albumin, kidney function and celiac serology often add more clinical value to a raised stool marker than ordering a second stool inflammation protein. The concerning pattern is not any one abnormality but several results that point toward inflammation, malabsorption, or blood loss.
Low hemoglobin, ferritin below 15 ng/mL, albumin below the laboratory reference range, raised platelets, or raised CRP can strengthen concern for clinically meaningful bowel disease. None is diagnostic of IBD. In fact, CRP may remain normal in mild ulcerative colitis, and ferritin can look falsely normal when inflammation raises it as an acute-phase protein.
Kantesti is 'n KI-aangedrewe bloedtoets-analisehulpmiddel that reads a CBC, iron studies and CRP in the same clinical frame, including whether a changing hemoglobin level might justify earlier review. Dr. Thomas Klein routinely cautions that an isolated CRP of 12 mg/L is nonspecific, whereas CRP 12 mg/L plus falling albumin and a calprotectin of 740 µg/g is a much more actionable cluster.
For patients whose iron values seem contradictory, our iron studies research guide explains transferrin saturation and ferritin during inflammation. A CBC result guide can also help you identify whether anemia is microcytic, inflammatory, or mixed.
Wanneer dit redelik kan wees om albei toetse aan te vra
Ordering calprotectin and lactoferrin together is usually unnecessary, but it can be reasonable when a specialist is reconciling discordant symptoms, a prior assay cannot be repeated, or a local pathway requires confirmation. Concordant results modestly increase confidence in an inflammatory signal; discordant results usually trigger review, not arithmetic averaging.
A high calprotectin with negative lactoferrin may reflect assay timing, a result near the cutoff, specimen heterogeneity, or analytical differences. A low calprotectin with positive lactoferrin deserves the same disciplined response: verify collection, review the exact assay, check symptoms and test for infection when appropriate. Neither combination has a validated shortcut to diagnosis.
Dual testing can also be useful in research settings where a protocol prespecifies both biomarkers. That is different from routine patient care, where duplicate testing can add cost without improving decisions. Ask the ordering clinician a simple question: “What will we do differently if the second test is positive?”
If a report looks internally inconsistent, use our 'n kwalitatiewe teenoor kwantitatiewe toetsgids to understand why “positive” and “high” are not interchangeable laboratory statements. Consistency of method matters more than collecting every available marker.
Wat IBD eintlik bevestig of uitsluit
IBD is diagnosed through a synthesis of symptoms, ileocolonoscopy with tissue sampling, histology, laboratory tests, and sometimes MRI or CT enterography—not from calprotectin or lactoferrin alone. Stool markers help decide who needs these investigations and whether inflammation may be changing over time.
Colonoscopy allows direct assessment of the terminal ileum and colon and permits tissue examination for chronic inflammatory features, infection, microscopic colitis, dysplasia, and other causes. Imaging is particularly valuable when Crohn’s disease may involve small bowel beyond the reach of a standard colonoscopy. A stool marker is a triage signal, not a microscopic diagnosis.
Do not confuse a fecal immunochemical test with either inflammatory marker. FIT detects human hemoglobin and is used primarily in colorectal cancer screening or lower-GI bleeding pathways, whereas calprotectin and lactoferrin detect neutrophil products. Our comparison of FIT and FOBT explains why a negative inflammation marker does not substitute for recommended cancer screening.
As of September 4, 2026, no major gastroenterology guideline recommends diagnosing Crohn’s disease or ulcerative colitis from a single stool biomarker threshold. That restraint protects patients from both missed disease and unnecessary lifelong diagnostic labels.
Simptome wat enige stoelgangtoetsuitslag oorskadu
Persistent visible rectal bleeding, black tarry stool, severe abdominal pain, fever, fainting, dehydration, rapidly worsening weakness, or unintended weight loss need timely medical assessment regardless of calprotectin or lactoferrin. A normal result should never be used to wait out a potentially urgent symptom pattern.
The urgent concern is physiology, not the label on a laboratory report. Frequent watery diarrhoea can produce low potassium, acute kidney injury, and orthostatic symptoms before an inflammation marker returns. Adults with inability to keep fluids down, confusion, fainting, or minimal urine output should seek urgent care.
New bowel symptoms after age 50, a strong family history of colorectal cancer, and iron-deficiency anemia alter the threshold for colon evaluation even when calprotectin is low. A stool marker does not assess cancer risk comprehensively. Our mucus in stool red-flag guide distinguishes common benign patterns from symptoms that need examination.
Children, pregnant people, older adults, and people using immune-suppressing medicines need individualized triage because their baseline risks differ. If you are unsure whether symptoms are urgent, contacting a local clinician or urgent-care service is safer than trying to interpret a number in isolation.
'n Praktiese gesprek om te voer na jou resultaat
The most useful follow-up question is: “Does this result change my need for infection testing, repeat testing, imaging, or endoscopy?” Bringing the exact value, assay name, symptom timeline, medicines, and previous results makes that conversation faster and more clinically precise.
Bring a list of the previous 14 days: stool frequency, overnight symptoms, fever, weight change, travel, antibiotics, NSAIDs, and family history. A calprotectin of 180 µg/g after a 3-day febrile diarrhoeal illness calls for a different plan than the same result after 4 months of nocturnal diarrhoea and weight loss.
Kantesti AI can help you organize accompanying blood reports before an appointment, but diagnosis and treatment decisions belong with the clinician who can examine you and arrange definitive testing. Our mediese valideringsbenadering explains how clinical oversight and source checking are built into responsible laboratory interpretation.
For complex cases, ask who will own the follow-up and when you should expect a repeat result or referral decision. The clinicians on our Mediese Adviesraad emphasize that a documented plan beats a vague instruction to “recheck later,” especially when inflammation markers and anemia move in the same direction.
Die besluitgerigte deurslag
Choose calprotectin first in most settings, use lactoferrin when it is your service’s validated alternative, and do not assume either result diagnoses IBD. A low result shifts attention toward functional and non-inflammatory causes, while a persistently high result identifies people who may need infection testing, specialist review, or endoscopy.
For uncomplicated chronic diarrhoea, one normal marker—calprotectin below 50 µg/g or a negative lactoferrin according to that laboratory—can reduce the likelihood of active inflammatory disease. For a value above 250 µg/g or a positive lactoferrin with persistent symptoms, the next question is cause, not certainty. Infection, medicine exposure, IBD, and other inflammatory conditions remain on the list.
Most patients find the ambiguity hardest in the 50–150 µg/g calprotectin zone. In my experience, the best next step is usually a carefully timed repeat, not a dietary cleanse, self-directed steroid use, or an internet diagnosis. Keep the same laboratory where feasible so the trend is interpretable.
Kantesti se KI-tegnologiegids describes how our systems preserve laboratory context while highlighting questions for medical review. The safe use of any AI interpretation is the same here: use it to prepare for a better clinical conversation, never to override red flags or replace diagnostic care.
Gereelde vrae
Is kalsiumkarbonaat beter as laktoferrien vir die opsporing van IBD?
Kalsiproktien word gewoonlik verkies vir vermoedelike IBD omdat dit wyd beskikbaar is as 'n kwantitatiewe toets en algemeen gebruikte moniteringdrempels het, soos minder as 50 µg/g en meer as 250 µg/g. Laktoferrien is ook 'n nuttige stoelgangmerker afkomstig van neutrofiele en kan goed presteer wanneer die laboratorium 'n gevalideerde toets gebruik. Geen merker bevestig IBD nie, want infeksies, NSAID's, divertikulitis en ander dermtoestande kan albei verhoog. Die beter toets is gewoonlik die een wat jou geneesheer saam met simptome kan interpreteer en met dieselfde laboratoriummetode kan herhaal.
Watter kalprotektienvlak is kommerwekkend?
'n Fekale kalprotektienvlak onder 50 µg/g is oor die algemeen gerusstellend vir volwassenes sonder alarm simptome, terwyl 50–150 µg/g dikwels as grensgeval beskou word en na 2–6 weke herhaal mag word. Waardes bo 150–250 µg/g is meer kommerwekkend vir intestinale inflammasie, en vlakke bo 250 µg/g spoor algemeen kliniese ondersoek of verdere toetsing aan. Eksakte aksie hang af van die toets, simptome, ouderdom, NSAID-gebruik en of die waarde styg. 'n Waarde van 600 µg/g na akute bakteriële diarree kan 'n ander betekenis hê as 600 µg/g gedurende verskeie maande van chroniese simptome.
Kan IBS hoë kalprotektien of laktoferrien veroorsaak?
Ongekompliseerde IBS veroorsaak gewoonlik nie verhoogde fekale kalsoproteïen of laktoferrien nie omdat IBS nie neutrofil-gedrewe derminflammasie produseer nie. Ligte kalsoproteïenverhogings tussen 50 en 150 µg/g kan voorkom van onlangse infeksie, NSAID-gebruik, ouderdomsverwante faktore, of toetsvariasie, so dit sluit nie outomaties IBS uit nie. 'n Positiewe laktoferrien of kalsoproteïen bo 250 µg/g moet 'n evaluering vir 'n inflammatoriese of infeksieuse oorsaak aanmoedig eerder as om IBS te aanvaar. IBS en IBD kan saam bestaan, wat 'n ander rede is waarom simptome en tendense saak maak.
Can a normal calprotectin rule out Crohn's disease?
'n Normale kalprotektien-uitslag verminder die waarskynlikheid van aktiewe koloniese IBD, maar kan nie Crohn se siekte heeltemal uitsluit nie, veral ligte of geïsoleerde Crohn se siekte van die dun derm. 'n Waarde onder 50 µg/g moet nie alarmkenmerke soos ystertekortanemie, gewigsverlies, nagtelike diarree, aanhoudende bloeding of 'n sterk familiegeskiedenis ignoreer nie. Klinici mag ileokolonoskopie, MR enterografie of kapselondersoek gebruik wanneer kliniese vermoede hoog bly. Die uitslag word die beste behandel as een waarskynlikheidsaanpassende stukkie getuienis eerder as 'n finale uitsluitingstoets.
Moet ek 'n grenswaarde-kalprotektien-resultaat herhaal?
'n Grensgeval-kalprotektienresultaat van 50–150 µg/g word dikwels herhaal na 2–6 weke wanneer simptome stabiel is en daar geen waarskuwingstekens is nie. Voordat dit herhaal word, doen klinici algemeen oorsig van onlangse gastro-enteritis, NSAID-gebruik, antibiotika en versamelingstoestande, omdat elkeen die waarde kan beïnvloed. Gebruik dieselfde laboratoriumtoets indien moontlik, aangesien resultate van verskillende metodes nie direk vergelykbaar mag wees nie. 'n Stygende resultaat na of bo 250 µg/g dra oor die algemeen meer kliniese gewig as 'n stabiele laegraadse verhoging.
Kan antibiotika stoelgangkalproteïen en laktoferrien beïnvloed?
Antibiotika kan stoelontstekingsmerkers indirek beïnvloed deur aansteeklike diarree te behandel, te veroorsaak of saam te val, en deur die dermmikrobioom te verander. 'n Persoon met antibiotika-verwante diarree moet beoordeel word vir oorsake soos Clostridioides difficile eerder as om 'n verhoogde kalsiproktien of positiewe laktoferrien as IBD te interpreteer. Daar is geen betroubare universele aantal dae om te wag na antibiotika voordat getoets word nie; tydsberekening hang af van simptome en die kliniese vraag. Aanhoudende diarree, koors of buikpyn na antibiotika benodig toetsing onder leiding van 'n klinikus eerder as selfbehandeling.
