The short version
$89, one kit, results in 3–4 days
The ColoFIT Home Collection Test ($89) is a fecal immunochemical test — a FIT — that screens for hidden blood in stool, an early sign of colorectal cancer. Order online, collect the sample at home, mail it back in the prepaid pack, results in 3–4 days. It is a screening filter, not a diagnosis: one round catches about four in five colorectal cancers, and a positive result is a reason to get a colonoscopy, not a verdict.

What a FIT actually detects — and what it cannot
A FIT — a fecal immunochemical test — looks for hidden blood in stool, blood in amounts far too small to see. It uses antibodies that bind the globin part of human hemoglobin, so it reacts to blood from the lower gut and not to animal blood or the food and drink compounds that tripped up the older guaiac test. Hidden blood can be an early sign of colorectal cancer, which is what the test screens for — and screening is all it does. It is not a diagnosis: a positive result has to be followed up with a colonoscopy or sigmoidoscopy to find the exact cause and source of the blood, and a negative result does not rule out disease. Some polyps and cancers bleed intermittently or not at all, and blood is not always evenly distributed through a stool sample, so a clean round can miss a lesion that was quiet that day.
How accurate is one round? The honest numbers
A meta-analysis of 19 studies in the Annals of Internal Medicine found that a single FIT detects about 79 percent of colorectal cancers, with specificity around 94 percent — roughly four in five cancers caught per round, and about one in five slipping through that year. The numbers for precancerous growths are humbler: a FIT catches only about a quarter of advanced adenomas, the polyps most likely to progress. Specificity of 94 percent means false alarms happen too: roughly 4 to 8 percent of average-risk people testing in a given round come back positive, and most of them will not have cancer. The test is built as an annual program for exactly this reason — a polyp or early cancer that stays quiet one year gets more chances to be caught in later rounds.
FIT vs. stool DNA vs. colonoscopy — picking the screen
Three screens, three trade-offs. A stool DNA test detects about 92 percent of colorectal cancers and about 42 percent of advanced adenomas, with specificity around 87 percent — better than a FIT on both counts, but it lists for several hundred dollars and is done every three years. A colonoscopy is the diagnostic standard: it sees the whole colon and removes polyps on the spot, but it needs bowel prep and sedation, and it is priced like a procedure, not a test. A FIT is the cheap yearly filter: no bowel prep, no diet or medication restrictions, one sample at home, once a year. A positive FIT always leads to a colonoscopy — the FIT finds the blood, the colonoscopy finds the source. And if your clinician recommends a colonoscopy, a FIT is not a substitute for it.
Who should consider it — and who should skip it
This test fits average-risk adults who want a yearly screen without a procedure: the product page recommends it once a year for people 45 and up at average risk for colon cancer, and screening guidance covers ages 45 to 75. It is the wrong purchase if you have symptoms — visible blood, a persistent change in bowel habits, or unexplained weight loss — or a family history of colorectal cancer, or a personal history of polyps or cancer: then the question belongs to a clinician, and the screen is usually a colonoscopy, not a FIT. Two practical exclusions from the product page itself: do not collect a sample during menstruation, or while you have actively bleeding hemorrhoids — either one can put blood in the sample that has nothing to do with cancer.
How at-home collection works
You order the test online and the kit ships to your door within 1–2 business days. When you are ready to collect, register the kit online, then place the collection paper inside the toilet bowl on top of the water and deposit the sample on top of it. Open the green cap, scrape the surface of the sample with the probe until the grooved portion is completely covered, then close the device tightly, wrap it in the absorbent pad, and seal it in the biohazard bag. The bag goes in the blue kit box, the box in the prepaid USPS return pack — drop it in your mailbox within 24 hours of collection. Results typically post to a secure portal 3–4 days after your sample arrives at the lab. HSA/FSA accepted. Testing is performed in a CLIA-certified clinical laboratory. The test must be taken by the purchaser, and it is available to adults 18 to 100. A 20% off promo code (MARKER20) is currently running — check the product page for the current price before ordering.
Reading the results: positive, negative, and the honest limits
A negative result means no hidden blood was detected in this round — keep screening yearly, and do not read it as a clean bill of health: a polyp or cancer that did not bleed that day is invisible to this test. A positive result means hidden blood was found — most positives are not cancer, but the result is a prompt, not a verdict: the next step is a colonoscopy to find where the blood is coming from. Read the result against the lab’s own report, not against figures from the internet, and read it once, in context: one round is one data point in a yearly program, not a diagnosis either way.
Abnormal results deserve follow-up with your healthcare provider, who reads them against your history and decides what, if anything, changes. No stool test diagnoses colorectal cancer on its own — only a colonoscopy with a biopsy can do that.
Common questions
Is this a home test kit?
Yes. The kit ships to your door, you collect the sample at home, and you mail it back in the prepaid return pack — no lab visit. Results arrive through a secure online portal, typically 3–4 days after your sample reaches the lab.
How often should I take it?
Once a year, for average-risk adults 45 and up — that is the product page’s recommendation, and the test is designed as an annual program: a lesion that stays quiet one year gets another chance to be caught the next. Ask your clinician what cadence fits your situation.
Do I need to fast or change my diet?
No. There is no bowel prep and no dietary or medication restrictions — unlike the older guaiac test, the immunoassay reacts only to human hemoglobin, so food, drink, and vitamins do not interfere.
What does a positive result mean?
Hidden blood was found in your stool. It does not mean cancer — most positives are not cancer — but it does mean a follow-up colonoscopy to find the source of the bleeding. A positive FIT is a prompt for that procedure, not a diagnosis.
Can the test miss cancer?
Yes. A single round catches about four in five colorectal cancers; cancers and polyps bleed intermittently, so a negative round is not a clean bill of health. That is why the test is built as a yearly program rather than a one-time check.
Who should not use this test?
People with symptoms, visible blood, a family history of colorectal cancer, or a personal history of polyps or cancer should talk to a clinician first — screening is for average risk, and the right screen in those cases is usually a colonoscopy. Do not collect during menstruation or with actively bleeding hemorrhoids.
Does it replace a colonoscopy?
No. It is a screening filter: if your clinician recommends a colonoscopy, the FIT is not a substitute, and a positive FIT leads to a colonoscopy anyway — the FIT finds the blood, the colonoscopy finds the source.
