What happens after FIT stool test?

A FIT looks for hidden blood in a stool sample. A result without detected blood does not explain every bowel symptom, so ongoing concerns still deserve medical review. If blood is detected, this can have several causes, including non-cancerous bowel conditions. It does not by itself diagnose cancer. Your clinician may recommend a colonoscopy to inspect the bowel more closely and, when needed, take tissue samples or remove a polyp.

Check how your clinic will communicate the result and make sure they have your current contact details. If follow-up is advised, arrange it even if you feel well. Before a colonoscopy, you may receive instructions about bowel preparation, medicines and eating or drinking. Tell the care team about blood-thinning medicines, diabetes treatment, pregnancy possibility and previous reactions to sedation. Do not change prescribed medicines without specific advice. Keep a record of new bowel changes, bleeding, abdominal discomfort or unexplained tiredness to discuss at the appointment.

Seek urgent care for heavy or repeated rectal bleeding, black stools, severe abdominal pain, persistent vomiting, fainting, confusion or marked weakness. Contact your clinician promptly for a new change in bowel habit, ongoing blood in the stool or symptoms that are worsening. A screening test is designed for people without symptoms and should not delay assessment when warning signs appear.

Ask what your result says, whether you need colonoscopy, how soon follow-up should happen, and what preparation involves. Clarify which medicines to continue, what symptoms need urgent attention, and how the result affects your future screening plan.
