Genital tract bacterial culture with antimicrobial susceptibility testing (qualitative and quantitative analysis of microbial load)

What This Test Measures

The test involves collecting a sample from your genital region (e.g., vagina, urethra, or cervix) using a sterile swab. The sample is then cultured to grow any bacteria present, allowing for identification and measurement of bacterial load. Some tests may also assess how different antibiotics affect the bacteria (antimicrobial susceptibility).

Why It’s Done

Doctors order this test to diagnose infections like bacterial vaginosis, urethritis, or sexually transmitted infections (STIs) such as chlamydia or gonorrhea. It’s also used to confirm infections after treatment or in cases where symptoms persist.

Sample Collection Process

A healthcare provider will insert a sterile swab into your genital area to collect a sample. This is usually quick and painless, though it may cause mild discomfort. You’ll be instructed to avoid sexual activity, douching, or using vaginal products for 24 hours before the test.

What to Expect After Testing

Results typically take 3–5 business days. If bacteria are found, your doctor will discuss treatment options, which may include antibiotics. Follow-up testing may be needed to confirm the infection is cleared.
