When to Seek Prompt Care

If you experience symptoms like unexplained weight loss, persistent changes in bowel habits, severe abdominal pain, or visible blood in your stool, contact your clinician promptly or seek urgent care.

What It Measures

The FIT test checks for blood in your poop that you can't see. It looks for a protein called hemoglobin. This protein is in your red blood cells. It comes from your lower intestines.

Why It's Ordered

Doctors often order this test to look for colon cancer. They also use it to find hidden bleeding in your stomach and intestines. This bleeding could be from other health problems.

Reference Range

FIT results are typically reported as positive, negative, or invalid, rather than a numerical value. Interpretation can vary by lab and clinical context.
