What Can Cause Positive Fit Test?

Abnormal or Positive Results
An abnormal or positive FIT result means that there was blood in your stool at the time of the test. A colon polyp, a pre-cancerous polyp, or cancer can cause a positive stool test. With a positive test, there is a small chance that you have early-stage colorectal cancer.

What happens if your fit test is positive?

A positive FIT test will tell your doctor that you have bleeding occurring somewhere in your gastrointestinal tract. This blood loss could be due to ulcers, bulges, polyps, inflammatory bowel disease, haemorrhoids (piles), swallowed blood from bleeding gums or nosebleeds, or it could be due to early bowel cancer.

Can a fit test be wrong?

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. This does not mean that a cancer was found—over 96% of those with an abnormal FIT will not have cancer.
