How the Test Works

A sterile swab is gently collected from the genital area to gather cells and fluids. The sample is then analyzed using a specialized probe to detect genetic material from STI-causing bacteria or viruses.

What to Expect Before the Test

No special preparation is needed. You may shower or clean the genital area lightly before the test, but avoid using soaps, lotions, or douches that day. Wear comfortable clothing for easy access.

What to Expect During the Test

The test is quick and usually takes less than a minute. You may feel a slight pinch or discomfort as the swab is inserted, but it’s generally brief and painless.

Possible Results and Next Steps

Results are typically available within 24 to 48 hours. If STIs are detected, your healthcare provider will discuss next steps, including treatment options and how to protect others.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This test is crucial for identifying STIs early, allowing for prompt treatment to prevent complications such as pelvic inflammatory disease, chronic pelvic pain, or infertility. It also helps prevent the spread of infections to partners.

Frequently asked questions

Why did my healthcare provider recommend this test?
Your provider may suggest this test if you have symptoms of an STI, have had unprotected sex, or are at higher risk for infections. It’s also recommended for regular screening in certain populations.
What does a positive result mean?
A positive result indicates the presence of an STI. Your provider will work with you to determine the best treatment plan and may recommend retesting after completing treatment to ensure the infection is cleared.
Can I have sex while waiting for results?
It’s best to avoid sexual contact until you have discussed your results with your healthcare provider and any necessary treatment is completed. This helps prevent spreading infections to partners.
