Digital rectal examDRE
A digital rectal exam is an examination of the lower rectum. The health care provider uses a gloved, lubricated finger to check for any abnormal findings.
How the Test is Performed
The provider will first look at the outside of the anus for hemorrhoids or fissures. Then the provider will put on a glove and insert a lubricated finger into the rectum. In women, this exam may be done at the same time as a pelvic exam.
Hemorrhoids are swollen veins in the anus or lower part of the rectum.
How to Prepare for the Test
For the test, the provider will ask you to:
- Try to relax
- Take a deep breath during the insertion of the finger into your rectum
How the Test will Feel
You may feel mild discomfort during this test.
Why the Test is Performed
This test is performed for many reasons. It may be done:
- As part of a routine yearly physical exam in both men and women
- When your provider suspects you are bleeding somewhere in your digestive tract
- When men are having symptoms that suggest the prostate is enlarged or you may have a prostate infection
In men, the test can be used to check the size of the prostate and to look for abnormal bumps or other changes of the prostate gland.
A digital rectal exam may be done to collect stool for testing for fecal occult (hidden) blood as part of screening for cancer of the rectum or colon.
