A positibo nga FIT test nagpasabut nga adunay nakit-an nga hemoglobin sa tawo sa imong hugaw. Dili kini makatambal sa kanser, apan nanginahanglan kini og diagnostic colonoscopy—mas maayo nga gihan-ay sulod sa 2 ka semana ug makompleto sulod sa 3 ka bulan; pangitaa dayon ang pag-atiman sa samang adlaw kung adunay daghang pagdugo sa tumbong, pagkalipong, grabe nga kasakit, o itom nga dagta nga hugaw.
- Positibo nga FIT test nagpasabut nga ang fecal immunochemical test nakadetekta og hemoglobin sa tawo sa hugaw; dili niini matino ang gigikanan sa pagdugo.
- Panahon sa Colonoscopy kinahanglan unta sulod sa 3 ka bulan sa usa ka positibo nga screening FIT; ang mga paglangan labaw sa 9 ka bulan nalambigit sa mas taas nga risgo sa kanser sa colon.
- Kaloob sa Kanser pagkahuman sa positibo nga FIT kasagaran mga 1 sa 50 hangtod 1 sa 10, samtang ang advanced polyps makit-an sa mga 1 sa 10 hangtod 1 sa 4, depende sa edad ug sa threshold sa programa.
- FIT threshold nagkalainlain sa serbisyo; ang mga symptomatic nga UK pathway sagad naggamit ug 10 µg hemoglobin kada gramo sa hugaw, samtang ang screening thresholds mahimong mas taas.
- Mga sintomas sa emergency naglakip sa padayon nga grabeng pagdugo, itom nga tarry stool, pagkalipong, grabeng sakit sa tiyan, o kakulang sa gininhawa kung naglingkod.
- Ayaw’g ulitin ang FIT sa pagkansela sa positibo nga resulta; ang ulahi nga negatibo nga sample dili kasaligang makawagtang sa panagsaang pagdugo sa polyp o kanser.
- Kasagarang hinungdan nga dili kanser naglakip sa hemorrhoids, anal fissures, diverticular disease, colitis, polyps, ug pagdugo gikan sa taas nga digestive tract nga dili kaayo kasagaran.
- Blood tests sama sa full blood count, ferritin, ug transferrin saturation makatabang sa pag-ila sa iron-deficiency anemia samtang naghulat ka sa colonoscopy.
Unsay Kahulugan sa Positibo nga FIT Test Karon
A positibo nga FIT test nagpasabot nga ang fecal immunochemical test nakadetek sa hemoglobin sa tawo sa stool sample, busa posible ang pagdugo sa ubos nga tinai. Dili kini usa ka emergency diagnosis sa iyang kaugalingon, apan kini usa ka resulta nga lihokan dayon kaysa bantayan sulod sa pipila ka bulan.
Sa akong clinical practice, ang labing mapuslanon nga unang sentence nga akong ikahatag mao kini: ang positibo nga resulta usa ka referral trigger, dili usa ka hukom sa kanser. Ang FIT makadetek sa globin nga bahin sa hemoglobin sa tawo, nga kasagarang mabungkag sa paglabay gikan sa tiyan ug gamay nga tinai; kana naghimo sa test nga medyo naka-focus sa pagdugo gikan sa colon o rectum. Ang usa ka microscopic bleed mahimong makahatag ug positibo nga resulta, bisan kung gibati nimo nga maayo ang tanan.
Sukad sa Septembre 4, 2026, ang mga screening programme magkalain gihapon sa ilang pagreport ug thresholds. Sa symptomatic nga UK primary-care pathways, 10 µg hemoglobin kada gramo sa hugaw usa ka kasagarang gigamit nga threshold alang sa dinalian nga colorectal assessment, samtang ang mga population-screening programme mahimong mogamit ug mas taas nga threshold sama sa 80 o 120 µg/g. Ang usa ka “positibo” nga resulta gikan sa usa ka laboratoryo busa dili numero nga mapuli sa lain.
Si Thomas Klein, MD, nagtambag sa mga pasyente nga tawagan ang clinician o screening service nga nag-order sa test sulod sa 2 ka adlaw sa trabaho kung walay referral plan nga giingon na. Hupti ang report, timan-i ang bisan unsang rectal bleeding o pagbag-o sa paggawas sa tinai, ug likayi ang pag-self-medicate sa iron gawas kung ang usa ka clinician nakakumpirma sa kakulangan. Ang among giya sa FIT ug FOBT differences nagpatin-aw ngano kining mas bag-ong stool test mas espesipiko alang sa dugo sa tawo kaysa sa daan nga guaiac testing.
Ngano Kinahanglan ang Colonoscopy Pagkahuman sa Positibo nga Resulta
Ang Colonoscopy mao ang standard next test human sa usa ka positibo nga FIT tungod kay kini makakita, makakuha ug sample, ug kasagaran makatangtang sa hinungdan sa pagdugo sa usa ka pamaagi. Ang pag-usab sa stool test dili luwas nga makapuli niini, tungod kay ang pagdugo sa tinai mahimong panagsa.
Ang FIT dili makaila sa usa ka gamay nga adenoma gikan sa usa ka dako nga kanser, usa ka nagdugo nga hemorrhoid, o colitis. Ang Colonoscopy nagsusi sa rectum ug colon direkta, nagtugot sa pagtangtang sa kadaghanan sa mga polyp, ug nagtugot sa pagsusi sa tissue kung ang usa ka apektadong dapit nagkinahanglan og klaripikasyon. Sa mga populasyon sa screening, mga 3% ngadto sa 10% sa mga tawo nga adunay positibo nga FIT adunay colorectal cancer, samtang mga 20% ngadto sa 40% adunay advanced adenomas o advanced serrated lesions; edad, sekso, threshold, ug gisundan nga screening nagbag-o sa mga numero sa igo.
The US Preventive Services Task Force states that a positive non-colonoscopy colorectal screening test requires colonoscopy for the screening benefit to be realised (Davidson et al., 2021). That wording matters: FIT is a two-step screening strategy, not a finished test. I have seen patients reassured by a subsequent negative home kit, only for colonoscopy to later identify a polyp that had simply not bled on the second day.
Si Kantesti usa ka AI blood test analyzer, so it can help organise related full blood count and iron-study results, but it does not diagnose the source of a positive stool test or replace endoscopy. If you have several reports, use a summary sa lab nga pang-doctor-visit to bring dates, medications, haemoglobin values, and symptoms together for the referral appointment.
Unsa Ka Dali Kinahanglan Maghan-ay og Colonoscopy?
Most people with a positive FIT should have colonoscopy completed within 3 months, and referral should start within days to a few weeks. A wait of several weeks is usually manageable if you are otherwise well, but a delay of 9 months or longer is not a comfortable “watch and wait” interval.
The practical target I use is simple: contact the ordering service within 48 oras, secure a referral within 2 ka semana, and aim for colonoscopy within 3 months. Access varies, and a clinician may choose CT colonography or specialist assessment first for someone too frail for sedation. What should not happen is an open-ended delay with no named service responsible for follow-up.
Corley and colleagues studied more than 70,000 FIT-positive patients and found that colorectal cancer incidence and stage began to worsen when colonoscopy occurred after about 6 ka bulan, with clearer adverse associations after 9 ka bulan (Corley et al., 2017). This observational study cannot prove that every individual delay causes progression, yet it is persuasive enough to guide service targets. A positive FIT paired with iron-deficiency anaemia deserves particular persistence.
If you are waiting, ask one concrete question: “What is my booked diagnostic date, and who should I call if it passes?” Record the name and number. Patients who also have mababang ferritin nang walang mabibigat na regla should mention it explicitly, because occult bowel loss is one possible explanation in adults.
Mga Sintomas nga Namula nga Nanginahanglan og Mas Dali nga Pag-atiman
A positive FIT plus heavy bleeding, black tarry stool, fainting, severe abdominal pain, or new breathlessness warrants same-day urgent assessment. These symptoms may indicate substantial blood loss, bowel obstruction, or another problem that should not wait for a routine endoscopy slot.
Go to emergency care or call local emergency services for repeated large-volume bright-red rectal bleeding, collapse, confusion, chest pain, or breathlessness at rest. Black, sticky, tar-like stool can indicate digested blood from higher in the digestive tract, particularly if it comes with dizziness or weakness. Iron tablets and bismuth can darken stool, but they do not usually make it sticky and tarry; uncertainty deserves assessment rather than internet detective work.
Contact your clinician the same day for persistent vomiting, a swollen abdomen with inability to pass stool or gas, fever above 38.0°C, or worsening cramping abdominal pain. New unintentional weight loss of more than 5% sa gibug-aton sa lawas sulod sa 6 hangtod 12 ka bulan, ongoing fatigue, or a clearly changing bowel pattern also strengthens the case for expedited review. The combination matters more than any one symptom alone.
A full blood count can reveal anaemia, but a normal haemoglobin does not rule out colorectal disease because bleeding may be small or intermittent. Read our practical guide to ubos nga sintomas sa red blood cell if fatigue, paleness, racing heartbeat, or exertional breathlessness has appeared alongside the FIT result.
Mga Kasagaran nga Hinungdan nga Dili Kanser sa Positibo nga FIT
Haemorrhoids, anal fissures, polyps, diverticular disease, colitis, and medication-associated mucosal bleeding can all cause a positive FIT. None of these explanations is a reason to skip colonoscopy unless the treating clinician has made another clear plan.
Haemorrhoids are common, especially with constipation, pregnancy, and prolonged straining, but they are a frequent trap in clinical reasoning. Seeing bright-red blood on paper and having known piles does not prove they caused the positive FIT. In adults aged 50 years or older, I generally regard a positive test as requiring bowel evaluation even when haemorrhoids seem plausible.
Benign polyps often bleed before they cause pain or a changed bowel habit; that is precisely why FIT screening works. Inflammatory bowel disease, infectious colitis, diverticulitis, and radiation-related bowel changes may also raise FIT values. A raised fecal calprotectin result can support intestinal inflammation, but it answers a different question and cannot exclude a polyp or cancer.
The evidence around medicines is nuanced. Aspirin, anticoagulants, and anti-inflammatory drugs may make an existing bleeding source more detectable, but they do not make a positive FIT meaningless; do not stop prescribed antiplatelet or anticoagulant treatment without the prescriber’s advice. Thomas Klein, MD, has seen avoidable clots occur when patients stopped medication abruptly after reading that it might influence a stool test.
Makahatag ba ang mga Period, Pagkaon, o Ehersisyo og Sayop nga Positibo?
Menstrual contamination and visible bleeding from the anal area can affect a FIT sample, but red meat and most foods do not cause a positive modern FIT. The fecal immunochemical test is not the same as an older fecal occult blood test that reacted to dietary peroxidases.
A person who is menstruating should usually wait until bleeding has stopped before collecting a routine screening sample, following the kit’s own instructions. If the sample was collected during a period, tell the service rather than assuming the result is invalid; some systems may repeat it, while others will still recommend investigation based on age and symptoms. Visible urinary blood can also contaminate a sample, so timing matters.
Unlike guaiac-based fecal occult blood tests, FIT does dili normally require avoiding red meat, citrus fruit, vitamin C, or broccoli. That distinction reduces false alarms and makes adherence easier. People often remember restrictions from a parent’s older test and unnecessarily delay screening; our explanation of FOBT results and false positives separates the two methods.
Strenuous endurance exercise can occasionally be associated with transient gut irritation or bleeding, particularly in dehydration or heat. If a marathon or ultradistance event occurred within 24 hangtod 48 ka oras of collection, mention it, but do not dismiss the result yourself. The related phenomenon of runner’s haematuria affects urine, not stool, and the two should not be confused.
Ngano nga Ang Pag-usab sa FIT Kasagaran Mao ang Sayop nga Sunod nga Lakang
A second negative FIT does not cancel a first positive FIT because polyps and cancers may bleed intermittently. Colonoscopy remains the appropriate diagnostic test unless a specialist chooses an alternative because of individual risk or access constraints.
The most common question I hear is, “Can I just redo it?” In a person with no symptoms and a sampling concern, the screening programme may occasionally request another specimen; that is a service-specific decision. But a self-arranged repeat test has a dangerous psychological effect: a negative result can make someone cancel the referral despite no direct look at the bowel.
FIT results fluctuate because bleeding is episodic, the sample comes from one bowel movement, and haemoglobin degrades with delayed or overheated transport. A result below a laboratory threshold means “not detected at this sample level,” not “the bowel is proven normal.” This is one reason a positive test has a different clinical meaning from a borderline blood result that can sensibly be rechecked.
If concern about a false positive is stopping you from booking, discuss the exact circumstances with the endoscopy team. For a broader comparison of strategy and limitations, see FIT batok sa colonoscopy. A colonoscopy has its own limits, but it offers an actionable finding that a repeat kit cannot.
Unsaon Pag-andam sa Luwas alang sa Colonoscopy
The bowel preparation, not the camera itself, is the part that most determines whether colonoscopy can reliably detect small lesions. Follow the written preparation schedule exactly, and contact the unit before changing diabetes medicines, iron, antiplatelets, or anticoagulants.
Most centres use a split-dose laxative regimen: part the evening before and part about 4 hangtod 6 ka oras before the procedure, with the final dose finished according to local fasting instructions. This timing consistently gives a cleaner right colon than taking all preparation the previous day. Clear yellow liquid stool near the end is generally the goal, although the unit’s own guidance always takes priority.
Dehydration is the preventable problem I see most often. Unless you have been told to restrict fluids for heart or kidney disease, drink clear liquids regularly while preparing; many units suggest roughly 2 to 3 litres across the preparation window. People with chronic kidney disease, heart failure, diabetes, or a history of low sodium need individual advice rather than a generic volume target.
Ask specifically about oral iron, which is commonly paused 5 hangtod 7 ka adlaw before colonoscopy because it darkens residual stool, and about GLP-1 medicines, insulin, and anticoagulants. Our coagulation panel giya explains why normal clotting results do not tell you whether it is safe to stop a prescribed anticoagulant without a plan.
Unsay Mahitabo sa Panahon sa Appointment sa Colonoscopy
Colonoscopy usually takes 20 to 45 minutes, although a total visit can last 2 to 4 hours because of consent, sedation, recovery, and possible polyp removal. Most patients remember pressure, bloating, or brief cramps more than sharp pain.
At check-in, the team should confirm the positive FIT result, symptoms, allergies, previous operations, and medication plan. Sedation practices vary: some people choose no sedation, some receive inhaled analgesia, and others receive intravenous sedation. You can ask whether a chaperone, a same-sex endoscopist where feasible, or communication support is available—practical details affect whether patients complete the test.
The endoscopist advances a flexible camera through the bowel and uses carbon dioxide or air to improve visibility. Carbon dioxide is absorbed faster and often reduces post-procedure bloating. Polyps under 10 mm are commonly removed during the same examination, and tissue samples may be taken from an affected area even when the lining appears only subtly changed.
After sedation, do not drive, operate machinery, sign legal documents, or drink alcohol for , hunong ang high-dose. Mild gas and a small streak of blood after polyp removal can occur, but increasing pain, fever, dizziness, or persistent bleeding needs urgent contact with the endoscopy unit. The Bristol stool chart can help you describe bowel changes accurately before and after the procedure.
Unsay Makita sa mga Resulta sa Colonoscopy
A colonoscopy after a positive FIT may find no significant abnormality, a removable polyp, inflammation, diverticular disease, haemorrhoids, or cancer. A normal examination is reassuring, but its follow-up interval depends on bowel-prep quality, completeness, family history, and local screening policy.
If no cause is found and the bowel preparation was excellent, clinicians often return an average-risk patient to routine screening rather than repeat colonoscopy immediately. A normal colonoscopy is not a lifetime guarantee: missed lesions are uncommon but possible, especially with poor preparation, incomplete examination, or a lesion type that is flat and subtle. Ask whether the caecum was reached and whether preparation was rated adequate.
Adenomas and serrated polyps are not cancer, but some can become cancer over years. Surveillance timing depends on the number, size, cellular features, and completeness of removal; a single small low-risk adenoma is handled very differently from 5 o labaw pa adenomas or a lesion 10 mm o mas dako. Pathology results commonly take 1 hangtod 3 ka semana, which can feel longer than it is.
If tissue examination identifies cancer, the next steps often include CT staging, blood tests, multidisciplinary review, and referral to colorectal surgery or oncology. A CEA value may be measured for baseline monitoring, but CEA cannot diagnose colorectal cancer or rule it out. Ang among artikulo bahin sa CEA ug CA 19-9 trends explains why tumour markers are adjuncts, not screening tests.
Mga Pagsusi sa Dugo nga Makadugang sa Mapuslanon nga Konteksto Samtang Naghulat Ka
A full blood count and iron studies can identify iron-deficiency anaemia, which strengthens the need to investigate occult gastrointestinal blood loss. Normal blood results do not make a positive FIT safe to ignore.
For non-pregnant adults, haemoglobin below roughly 130 g/L sa mga lalaki o 120 g/L sa mga babaye meets common anaemia definitions, although laboratories and clinical context vary. Ferritin below 30 µg/L often supports depleted iron stores; with inflammation, ferritin can look falsely reassuring because it rises as an acute-phase protein. A low transferrin saturation, often below 20%, adds useful context.
Si Kantesti usa ka AI lab test interpretation service that places haemoglobin, mean cell volume, ferritin, C-reactive protein, and kidney function in one longitudinal view. That is useful when a positive FIT sits beside fatigue or low iron, but it must support—not postpone—the endoscopy pathway. We recommend downloading original laboratory reports and sharing them with the clinician who owns the referral.
A falling MCV, rising RDW, and declining ferritin can precede overt anaemia by months. The giya sa pagtuon sa puthaw explains why serum iron alone varies too much during the day to diagnose deficiency. If you develop palpitations, chest discomfort, or breathlessness while waiting, request assessment sooner rather than simply increasing dietary iron.
Mga Tambal, Edad, ug Kasaysayan sa Pamilya nga Makapausab sa Triage
Anticoagulants, antiplatelets, a first-degree relative with colorectal cancer, prior polyps, and inflammatory bowel disease should all be flagged at referral after a positive FIT. These factors influence risk assessment and procedure planning, but none makes a positive result automatically harmless.
Aspirin, clopidogrel, warfarin, apixaban, rivaroxaban, and similar medicines may increase the visibility of bleeding from a lesion that was already there. Do not stop them independently: the risk of stroke, venous thrombosis, or coronary events may outweigh procedure-related bleeding risk. The endoscopy team will provide a medication-specific plan based on kidney function, indication, and whether polyp removal is anticipated.
A first-degree relative diagnosed with colorectal cancer before age 50 ka tuig, or two first-degree relatives diagnosed at any age, may indicate a higher-risk family pathway. Tell the clinician about relatives with colon cancer, endometrial cancer, ovarian cancer, or numerous polyps, including their ages at diagnosis. Family history is often recorded incompletely because people remember “cancer” but not the organ or age; a quick family call can change triage.
Si Kantesti usa ka AI biomarker interpretation platform that can help families track consented laboratory trends, but a family-risk assessment cannot diagnose inherited cancer syndromes. For a practical record to bring to primary care, review cancer-related family risk markers. Genetic counselling may be appropriate even when routine blood tests are normal.
Kung Ang Colonoscopy Nalangan, Dili Kompleto, o Dili Angay
CT colonography is a common alternative when colonoscopy is incomplete or unsafe, but it cannot remove polyps or take tissue samples. A positive FIT still needs a documented diagnostic plan even when standard colonoscopy is not feasible.
Frailty, severe heart or lung disease, difficult bowel anatomy, anticoagulation complexity, or an incomplete first examination may lead a specialist to recommend CT colonography. It uses bowel preparation and gas insufflation, usually without sedation, and is good at detecting larger growths. If it identifies a suspicious polyp or affected area, colonoscopy may still be needed for removal or tissue examination.
Capsule colon imaging is available in selected settings, but availability and follow-up pathways are inconsistent. It is not a shortcut around bowel preparation, and a positive finding still commonly leads to conventional endoscopy. If appointments are cancelled repeatedly, ask for the reason, the alternative, and the target date in writing; uncertainty is harder to resolve when everyone assumes someone else has rebooked it.
Kantesti’s medical content is reviewed with clinical oversight, and our medical validation approach explains how we separate pattern interpretation from diagnosis. A digital report can organise your questions, but only the treating service can decide whether urgent imaging, anaesthetic review, or a different test is clinically appropriate.
Unsay Buhaton Pagkahuman sa Normal nga Colonoscopy
A high-quality normal colonoscopy after a positive FIT is reassuring, but new bleeding, iron-deficiency anaemia, or persistent symptoms still deserve reassessment. The next screening interval should come from the endoscopy report rather than an assumed universal rule.
Read the report for three items: preparation quality, whether the examination reached the caecum, and the recommended follow-up date. In many programmes, an average-risk person with a complete high-quality normal colonoscopy returns to routine screening after several years, but national policies differ. Do not keep doing annual private FIT tests unless your clinician recommends it; unnecessary testing can create confusing cycles of repeat procedures.
Persistent fatigue or low ferritin after a normal colonoscopy may require assessment for upper gastrointestinal loss, coeliac disease, menstrual loss, kidney disease, dietary deficiency, or malabsorption. A negative colonoscopy does not investigate every part of the digestive tract. The gluten challenge guidance is relevant only if coeliac testing is being considered and you are currently eating gluten.
I tell patients that reassurance should be specific, not vague: “The colon was adequately examined on this date, and here is what would bring me back sooner.” New black stool, recurrent visible rectal bleeding, unexplained weight loss, or a haemoglobin fall of 10 g/L or more from a prior baseline should prompt a clinician review. Keep the report with your health history records.
Mga Pangutana nga Itanong sa Imong FIT Follow-Up Appointment
The most useful follow-up questions are when the diagnostic test will occur, whether symptoms change urgency, and how medicines should be managed. A written list reduces missed details when an unexpected positive screening result makes the conversation feel rushed.
Ask: “What was my FIT value and threshold, if it was reported quantitatively?”, “Is colonoscopy the right next test for me?”, and “What symptoms mean I should call sooner?” A higher quantitative value can correlate with a greater likelihood of significant bowel findings, but no single number diagnoses cancer. The outcome of a proper investigation matters far more than trying to interpret a result in isolation.
Bring a medication list with doses, previous colonoscopy and pathology reports, family cancer history, and dates of bleeding or bowel changes. If fatigue is part of the picture, include haemoglobin, MCV, ferritin, and transferrin saturation results. Kantesti AI can help you recognise those blood-test patterns and produce a time-ordered report, while the specialist decides what they mean for your bowel investigation.
My final clinical point is deliberately plain: do not let embarrassment slow you down. Colorectal teams discuss stool, rectal bleeding, and bowel habits every day; clear answers improve care. Our physicians and governance process are described by the Medical Advisory Board, and you can use the Kantesti to understand where AI interpretation is helpful and where direct medical assessment remains indispensable.
Kanunay nga Gipangutana nga mga Pangutana
Unsa ka dinalian ang positibo nga FIT test?
Ang positibo nga FIT test kasagaran dinalian igo aron sugdan ang referral sulod sa pipila ka adlaw ug makompleto ang colonoscopy sulod sa mga 3 ka bulan, apan dili kini awtomatikong emerhensya kung maayo ang imong gibati. Nakaplagan sa ebidensya sa pagpaniid ang mas grabe nga mga resulta sa colorectal cancer kung ang follow-up colonoscopy nadugay lapas sa mga 6 ka bulan, nga adunay mas klaro nga risgo pagkahuman sa 9 ka bulan. Pangita og pag-atiman sa samang adlaw kung ang positibo nga resulta mahitabo uban ang bug-at nga pagdugo sa tumbong, itom nga tarry stool, pagkalipong, grabeng kasakit sa tiyan, kasakit sa dughan, o kakulang sa gininhawa sa pagpahulay.
Unsa ang tsansa nga ang positibo nga FIT test nagpasabot og kanser?
Ang positibo nga FIT test nagpasabot nga posible ang colorectal cancer apan dili sigurado; ang kanser makit-an sa gibana-banang 3% hangtod 10% sa mga partisipante sa screening nga positibo sa FIT, depende sa edad, sekso, threshold sa pagsulay, ug programa sa screening. Ang mga advanced polyps o advanced serrated lesions mas sagad makit-an, kasagaran sa mga 20% hangtod 40% sa mga tawo. Gikinahanglan ang colonoscopy tungod kay kini makalahi sa kanser gikan sa mga polyps, haemorrhoids, panghubag, ug uban pang mga hinungdan sa dugo sa bangkito.
Makapahinabo ba ang almoranas sa positibo nga FIT test?
Ang mga hemorrhoid makatampo sa positibo nga FIT test kay mahimo kini nga magpagawas ug dugo sa tai, ilabi na panahon sa pagkadunot o pag-ukay. Bisan pa, ang nahibal-an nga mga hemorrhoid dili kasaligan nga makapatin-aw sa positibo nga resulta sa usa ka hamtong nga kwalipikado alang sa bowel screening. Ang colonoscopy o uban pang imbestigasyon sa tinai nga gipahinungod sa clinician nagpabilin nga angay tungod kay ang mga hemorrhoid ug polyp mahimong magkauban.
Kinahanglan ba nako usbon ang akong FIT test kung positibo kini?
Ang balik-balik nga FIT test kasagaran dili ang husto nga paagi aron ibaliwala ang positibo nga resulta sa FIT tungod kay ang pagdugo sa tinai dili kanunay ug ang ulahi nga negatibo nga sample mahimong makalimtan ang parehas nga samad. Ang orihinal nga positibo nga resulta kinahanglan mosangpot sa colonoscopy gawas kon ang serbisyo sa screening o espesyalista piho nga mohangyo og balik tungod sa problema sa pagkolekta. Ang negatibo nga balik-balik dili mopuli sa direktang pagsusi sa tinai human sa nakumpirma nga positibo nga resulta.
Unsay FIT level ang gikonsiderar nga positibo?
Ang usa ka FIT nga lebel giisip nga positibo kung ang tambok nga hemoglobin moabot o molapas sa threshold nga gigamit sa maong laboratoryo o programa sa screening. Ang mga symptomatic nga UK pathway kasagarang naggamit ug 10 µg nga hemoglobin matag gramo sa tambok, samtang ang mga serbisyo sa pag-screen sa populasyon mahimong mogamit ug thresholds nga mga 80 o 120 µg/g. Ang mas taas nga kantidad mahimong makadugang sa kabalaka alang sa importante nga sakit sa tinai, apan walay numerikal nga FIT value nga makakumpirma o makawagtang sa kanser nga walay diagnostic nga imbestigasyon.
Makapahimo ba ang pagkaon o tambal nga positibo ang FIT test?
Ang pula nga karne, bitamina C, ug mga utanon dili kasagaran hinungdan sa positibo nga modernong fecal immunochemical test kay ang FIT nakadetektar sa tawhanong globin imbes nga dietary peroxidase activity. Ang mga anticoagulants, aspirin, ug mga tambal nga anti-inflammatory mahimong makapadali sa pagkakita sa naglungtad nga tinubdan sa pagdugo, apan kini dili makapawala sa kaimportante sa positibo nga resulta. Ayaw huntawa ang warfarin, apixaban, clopidogrel, aspirin, o susamang gireseta nga mga tambal kon walay tambag gikan sa clinician nga nagdumala niini.
