How Long After Sex Should I Get Tested for STD?

Scheduling a rapid STD test after having sex with a new partner is an important step in protecting your sexual health. But you may wonder, “How long after sex should I get tested for STDs?” 

Different STDs have different incubation periods, which means they may not show up on an STD test for some time. Additionally, many factors can affect when you should get tested, such as the type of sexual contact you had and whether you suspect you were exposed to any specific STDs.

Too often, people make the mistake of testing for STDs within one or two days after sex, then get negative test results and never suspect they have an STD. Worse, many STDs are asymptomatic, meaning people can have them for months or years without knowing. 

Sticking to a proper STD testing schedule can help you stay informed about your sexual health. 

Understanding the Timing: When To Get Tested for STDs

Before you can know how long after sex to get tested for STDs, you should understand incubation periods and factors affecting when to get tested. 

Incubation Periods

STD incubation periods are the amount of time necessary for the body to develop a response to an infection. During this period, the person does not yet develop symptoms of the infection, and they may not be able to infect others. Their STD may also not show up on a 10-panel STD test during the incubation period. 

Eventually, the body prepares for an antibody attack to fight off the infection. At this point, symptoms may occur, and the STD may be detectable. But keep in mind that many STDs are asymptomatic. 

STD-Specific Testing Windows

Each STD has its own window period, which is different from the incubation period. A window period is the amount of time it takes to get a positive result for an STD or the time between when you were exposed to an STD and when a test can detect it in your system. 

The window periods for common STDs are as follows:

  • HIV: 30 to 90 days for an antibody test 
  • Chlamydia: One to two weeks
  • Gonorrhea: Five days to two weeks
  • Syphilis: Within three weeks after sores appear

Importance of Early Detection

Identifying STDs early on can improve your outcomes. You can begin treatment immediately, preventing complications and permanent health problems that sometimes result from untreated infections. You can also avoid spreading the STD to a sexual partner.

Factors Influencing Testing Time 

So, “How long after sex should I get tested for STDs?” Two main factors influence the answer to this question:

  • The type of sexual contact: Some STDs only spread through genital sex, while others also spread through oral sex. 
  • Known exposure to an STD: If you believe you were exposed to a specific STD, you'll need to wait for that infection's window period to ensure the accuracy of your test results. 

Common STDs and Their Testing Guidelines

Each STD has unique testing guidelines that you must follow to ensure the accuracy of your test results. 

Chlamydia and Gonorrhea

While chlamydia and gonorrhea are two distinct STDs, they are often grouped together and tested for at the same time. These infections are very common; chlamydia is the most reported STI in the United States, while gonorrhea infects more than 700,000 people in the U.S. annually.

Still, they have different window periods. The chlamydia testing timeline is at least one to two weeks after exposure, while the gonorrhea detection time is between five days and two weeks. As a result, it makes sense to wait two weeks after exposure to test for both of these STDs. 

Both chlamydia and gonorrhea are often asymptomatic. Those who do experience symptoms sometimes see:

  • Painful urination
  • Pain during sex
  • Abnormal discharge
  • Abnormal vaginal bleeding
  • Pain/swelling in one testicle

HIV Testing

The human immunodeficiency virus (HIV) impacts more than one million people in the U.S. Detecting HIV as soon as possible is important so that you can begin treatment quickly and avoid accidentally spreading the infection to a sexual partner. 

The HIV testing window is typically between 30 to 90 days after exposure for antibody tests. Meanwhile, a nucleic acid test (NAT) can detect HIV within 10 to 33 days after exposure. 

Infected individuals may begin experiencing symptoms as soon as two to four weeks after exposure. HIV symptoms mimic the flu and may include the following:

  • Fever
  • Muscle pain
  • Sore throat
  • Headache
  • Swollen lymph glands

If you conduct a rapid or self-test for HIV and it is positive, you should visit a healthcare provider for follow-up testing to ensure that the positive result is accurate. If you conduct a lab test and it is positive, the lab will likely conduct follow-up testing on the same blood sample as your original test. 

HIV tests are generally accurate, but follow-up testing can further confirm results. On the same note, if your initial HIV test is negative, be sure to get tested again after the window period to confirm the results. If the second test is negative and you have not had any HIV exposure during the window period, you can assume you do not have HIV. 

Herpes and Syphilis

Herpes and syphilis have unique incubation periods, but their window periods are similar. Both STDs take around three to six weeks after exposure to show up on an STD test. However, experts typically recommend herpes simplex virus testing around 16 weeks after exposure, while most syphilis screening guidelines recommend getting tested for syphilis around 90 days after exposure. 

Herpes can produce symptoms such as:

  • Small bumps or blisters around the mouth, genitals, or anus
  • Pain or itching around the genitals
  • Painful urination

Meanwhile, syphilis often begins with a painless sore on the genitals or mouth, which then transitions to a rash. 


Trichomoniasis is one of the most common STIs in the U.S., with as many as 8 million cases occurring annually.

The trichomoniasis test period is anywhere from three to seven days after exposure. This STD often produces no symptoms in men and women, but those who do have symptoms may experience:

  • Pain during urination and intercourse
  • Foul-smelling discharge that is white or green
  • Genital redness and itchiness

Navigating Sexual Health: Regular Testing and Prevention

While many people wonder, “How long after sex should I get tested for STDs?” you shouldn't only get testing after intercourse. Whether you have symptoms or not, getting tested for STDs regularly is an important step in staying informed about your sexual health and being a responsible sexual partner. 

Routine Testing for Sexually Active Individuals

If you are sexually active, you should seek asymptomatic STD testing regularly. The CDC recommends the following testing schedule at a minimum: 

  • Everyone ages 13 to 64: At least once for HIV
  • Sexually active women under 25: Annually for gonorrhea and chlamydia
  • Those having unprotected sex or sharing needles: Annually for HIV
  • All pregnant women: Once for syphilis, HIV, and hepatitis B
  • All women with high-risk pregnancies: Once for gonorrhea and chlamydia
  • Men who have sex with men: HIV tests every three to six months and syphilis, chlamydia, and gonorrhea tests annually
  • Anyone with multiple partners: Full-panel sexual health screening at least once annually

Preventive Measures

Along with seeking STD testing regularly, you should know and take preventive measures for STDs. These include:

  • Abstinence, which is the most reliable way to avoid infection
  • Mutual monogamy, or sex with only one partner who also only has sex with you
  • Condom use, as most STDs are not spread with the use of condoms
  • Vaccination against HPV, hepatitis A, and hepatitis B, along with other vaccines as they become available

Dealing With a Positive Result

If you test positive for an STD, don't panic. Most STDs are completely curable with treatment, while those that aren't are at least treatable. 

Talk to your healthcare provider about your best next steps. You'll likely need to take medication to kill the infection.

Also, notify your sexual partners about your positive test result and urge them to seek testing as well. 

Resources and Support

If you think you may have an STD, remember that you are not alone. Review these resources for where to get an STD test and find support:
