الوصف
Fecal Immunochemical Test (FIT) is a rapid, qualitative test designed especially to detect human hemoglobin (hHgb) in fecal samples using immunochemical
methods, improving specificity for the detection of lower gastrointestinal disorders, including colorectal cancers and adenomas, without the need for
dietary restrictions. Screening for colorectal cancer is likely to improve the odds of detecting cancer at an early stage, reducing mortality.
