Cervical Swab for Gram Stain

Specimen Required

Cervical Swab

Fasting Required

Purpose of the Test

The test is ordered when a patient has symptoms of a genital tract infection, such as abnormal vaginal discharge, pelvic pain, or pain during sexual intercourse. It is also used for routine screening for sexually transmitted infections (STIs) such as chlamydia and gonorrhea.

When this test is required

The test may be requested when a patient has symptoms of a genital tract infection, such as abnormal vaginal discharge, pelvic pain, or pain during sexual intercourse, or when they are at increased risk for STIs, such as having unprotected sex with a new partner. It may also be done as part of routine gynecologic exams or prenatal care.

What the Test Detects

Cervical swab for Gram stain is used to identify bacterial infections in the female reproductive system, specifically the cervix. The test involves staining a sample of cervical secretions with a special dye that makes bacteria visible under a microscope.

Preparation for the Test

No specific preparation is needed for the test. However, it is recommended to avoid douching, using vaginal creams or spermicides, or having sexual intercourse for at least 24 hours prior to the test to avoid contaminating the sample. It is important to discuss any concerns or questions with your healthcare provider before the test.

Sample Requirements

To perform the test, a healthcare provider uses a swab to collect a sample of cervical secretions. The swab is then placed onto a glass slide, stained with a special dye, and examined under a microscope.

Additional Notes

While cervical swab for Gram stain is a relatively simple and safe test, it is important to remember that it is not a definitive diagnosis of a bacterial infection. Further testing may be necessary, such as culture or polymerase chain reaction (PCR) testing. Additionally, the test does not screen for all types of STIs, and additional testing may be necessary to rule out other infections. It is important to discuss any concerns or questions with your healthcare provider before the test.
