Digital rectal exam

Indications
Indications
Definition

A digital rectal exam is an examination of the lower rectum. The doctor uses a gloved, lubricated finger to check for abnormalities.


Alternative Names

DRE


How the test is performed

The doctor will first examine the outside of the anus for hemorrhoids or fissures. Then the doctor will put on a latex glove and insert a lubricated finger into the rectum. In female patients, this exam may be done together with a pelvic exam.


How to prepare for the test

The doctor will ask you to try to relax before the test and to take a deep breath during the actual insertion of the finger into the rectum.


How the test will feel

You may feel mild discomfort during this test.


Why the test is performed

This test is performed for various reasons, but is most often done as part of a routine yearly physical examination in both men and women.

In men, the test is used to examine the prostate, looking for abnormal enlargement or other signs of prostate cancer.

In women, a digital rectal exam may be performed during a routine gynecologic examination.

A digital rectal exam is also done to collect stool for testing for fecal occult (hidden) blood as part of screening for colorectal cancer.

This procedure is also done before other tests, such as a colonoscopy, to make sure nothing is blocking the rectum before inserting an instrument.
