The fecal immunochemical test (FIT) is a diagnostic technique that examines stool samples for traces of non-visible blood, which could potentially indicate conditions including bowel cancer. [1] Symptoms which could be caused by bowel cancer and suggest a FIT include a change in bowel habit, anaemia , unexplained weight loss, and abdominal pain .
The American College of Gastroenterology has recommended the abandoning of gFOBT testing as a colorectal cancer screening tool, in favor of the fecal immunochemical test (FIT). [3] The newer and recommended tests look for globin, DNA, or other blood factors including transferrin, while conventional stool guaiac tests look for heme.
The gold standard of early detection of colon polyp/cancer is the invasive colonoscopy, but with high expense about $557, while tumor marker M2-PK Test expense only about $15-$25. The invasive colonoscopy makes acceptance of it low among patients, so relatively cheap non-invasive M2-PK Test is a good choice for detection early polyp/cancer. [2]
M2-PK, as measured in feces, is a potential tumor marker for colorectal cancer.When measured in feces with a cutoff value of 4 U/ml, its sensitivity has been estimated to be 85% (with a 95% confidence interval of 65 to 96%) for colon cancer and 56% (confidence interval 41–74%) for rectal cancer.

The consequences of overdiagnosis and overtreatment resulting from cancer screening can lead to a decline in quality of life, due to the adverse effects of unnecessary medication and hospitalization. [10] [12] [13] The accuracy of a cancer screening test relies on its sensitivity, and low sensitivity screening tests can overlook cancers. [10]
The Cologuard test is a first-line colorectal cancer screening test for adults age 45 or older at average risk for the disease. Upon launch in 2025, the Cologuard Plus test will be supported by ...
The 10-year life expectancy limit on some cancer screening guidelines, such as breast cancer screenings, also raised eyebrows — 27% of those surveyed said it was too short.
Fecal occult blood testing (FOBT), as its name implies, aims to detect subtle blood loss in the gastrointestinal tract, anywhere from the mouth to the colon.Positive tests ("positive stool") may result from either upper gastrointestinal bleeding or lower gastrointestinal bleeding and warrant further investigation for peptic ulcers or a malignancy (such as colorectal cancer or gastric cancer).
