Colonoscopy is a test that allows your
doctor to look at the inner lining of your
large intestine (rectum and colon). If a sample of tissue (biopsy) was collected during the colonoscopy, it will
be sent to a lab for tests.
- Samples of colon tissue are usually sent to a
pathology lab, where they are looked at under a microscope for
- Other samples of colon tissue may be sent to a
microbiology lab to see whether an infection is present.
Your doctor may be able to tell you the results immediately
after the procedure. Other test results are ready in 2 to 4 days. Test results
for certain infections may be ready in several weeks.

inflammation are present.
