Endocervical gram stain
Alternate Names : Gram stain of cervix
Definition
Endocervical gram stain is a method of identifying bacteria on tissue from the cervix using a special series of stains.
Why is the Test Performed?
The test is used to detect and identify abnormal bacteria in the area of the cervix. If you develop signs of an infection or suspect that you have a sexually transmitted disease (such as gonorrhea), this test can help confirm the diagnosis, and identify the organism that is causing the infection.
How is the Test Performed?
The health care provider will obtain a tissue sample from the lining of the cervical canal (the opening to the uterus). You lie on your back with your feet in stirrups. As in a regular pelvic examination, a speculum (an instrument used to stretch open the vagina in order to better examine some of the pelvic organs) will be inserted and opened slightly. The cervix is cleaned so there is no mucus. A dry, sterile swab is then inserted and rotated in the cervical canal. It may be left in place for several seconds to absorb as many of the organisms as possible. The swab is then removed and sent to a laboratory, where it will be smeared on a slide. A series of stains called a gram stain is applied to the specimen. A laboratory technician examines the stained smear under the microscope for the presence of bacteria. The color, size, and shape of the cells help identify the type of bacteria.
How to Prepare for the Test?
Do not douche for 24 hours before the procedure.
How will the Test Feel?
You may feel minor discomfort during specimen collection. This procedure feels very much like a routine Pap smear.
