Quantitative Faecal Immunochemical Test (qFIT)

Alias: QFIT, Faecal Occult Blood, FOB

Discipline: Clinical Chemistry

Test information: The Quantitative Faecal Immunochemical Test (qFIT) is a test to detect hidden or 'occult' blood in stool samples. Unlike older FOB tests, qFIT test uses antibodies that specifically recognise human haemoglobin and are consequently more sensitive and specific tests than the guaiac based FOB test. It also allows the amount of haemoglobin to be measured. QFIT should be offered to adults without rectal bleeding who were classed as "low risk, but not no risk" of having colorectal cancer.
