What percentage of fit tests are positive?

In recent studies of initial fecal immunochemical testing, 7% to 8% of tests were positive. Patients who are considering colorectal cancer screening with fecal immunochemical testing (FIT) might be interested in their probability of testing positive and requiring subsequent colonoscopy.

And, like any test, FIT may give an abnormal result even though there is nothing wrong. On average, 15% of individuals screened with FIT will have an abnormal FIT result and will require additional testing.

What can a fit test diagnose?
