How do I know if I have an STD?

If you’ve been sexually active, it’s important for your sexual health to know if you have an STD. You may experience some of the more common symptoms if you have an infection:

Unusual discharge from the penis or vagina.
Pain or a burning sensation during urination or sex.
Sores, bumps, or rashes in the genital area, mouth, or anus.
Persistent itching in the genital area.
Swelling or redness in the genital area.

It’s critical to know that many STDs can be asymptomatic, with some diseases up to 80% being undetected per the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO). To avoid worsening symptoms or infecting partners, get tested for confirmation. Positive test results are really the only true way of determining an infection. Regular testing is crucial, especially if you have multiple partners or are engaging in unprotected sex.

When should you test for STDs?

STD	Incubation Period After Exposure
Oral Herpes	2–12 days
Genital Herpes	2–12 days
HIV	2–4 weeks
Gonorrhea	2-7 days
Chlamydia	7–21 days
Syphilis	10 – 90 days
Hepatitis A	15–50 days
Hepatitis B	4–25 weeks
Hepatitis C	2 weeks – 6 months
Trichomoniasis (Trich)	5–28 days

What do STD test panels test for?

The most comprehensive 10-test panel will provide a confirmation of infection status across different bacterial or viral diseases, including HIV type 1 & type 2 antibody/antigen (4th gen), herpes type 1 & type 2, hepatitis A, hepatitis B & hepatitis C, chlamydia, gonorrhea and syphilis.

How much do STD tests cost in O'Fallon?

STD testing costs can vary widely in O’Fallon based on the type of test(s) you purchase, speed of results and appointment times, and location.

Private STD testing offers walk-in appointments, comprehensive test panels and fast results. You can expect to pay no more than $250 to get a 10-test panel in O’Fallon. Results are delivered quickly, within 1-2 days.

At-home testing is also an option, with popular online manufacturers offering test panels for up to $350. The primary benefit of this option is testing in the convenience of your own home. Simple blood tests, urine samples or swaps are taken and mailed back to the lab. Results are typically available in 7-10+ days.

Local low-cost or potentially free clinics also are available. However, these locations may require appointments, may not test for all STDs and are not as immediate as private testing.

Can you get same-day STD tests in O'Fallon?

Yes! Private testing offers same-day, no appointment necessary STI testing in O’Fallon. Once you purchase your selected tests (no doctor script required), you can just walk into the private lab with your order.

How fast do you get STD test results in O'Fallon?

STD test result times will vary based on the type of test. Private STD testing in O’Fallon will deliver results within 1-2 days. At-home test results could be 7+ days, and local clinics will vary based on a number of factors.

Are appointments needed for STD testing in O'Fallon?

If you choose private STD testing as your preferred option, you don’t need an appointment to get your testing done. Just purchase the order and walk into one of the 5,000+ CLIA-Certified labs across the United States.

Local STD clinics may require appointments and should be checked on a case-by-case basis. At-home tests are also an option. Both will likely take longer to test and receive your results.
