STI testing

Oral or anal STI test: when is a urine test not enough?

Many people automatically think of urine when it comes to an STI test. But an STI is not always located where you test. If you've had oral sex, a throat test might be needed. If you've had anal sex, an anal test might be needed. If you only test urine, you might miss an infection in another area.

Quick choices

Only had vaginal sex? Then a genital STI test is usually appropriate.
Had oral sex? Then a throat test might be needed.
Had anal sex? Then an anal test might be needed.
Had multiple types of sex? Then test per contact area.

Why the testing site is important

For STIs like chlamydia and gonorrhea, the testing site is very important. These infections can occur in different parts of the body, such as the penis, vagina, throat, or anus.

A urine test primarily looks for an infection in the genital area. If you've also had oral or anal sex, testing only urine doesn't always provide a complete picture. An infection in the throat or anus can then go unnoticed.

This makes it extra important to carefully consider the type of sexual contact you've had. Not every STI causes clear symptoms, and sometimes you may not notice anything at all even though you could be infected.

When do you choose a urine test?

A urine test is particularly suitable when the potential risk is in the genital area. This might be the case, for example, after unprotected vaginal sex or if you experience symptoms when urinating.

A urine test may be appropriate for:

unprotected vaginal sex;
pain or discomfort when urinating;
discharge from the penis or vagina;
sexual contact involving only the genital area;
follow-up after contact with someone who tested positive for chlamydia or gonorrhea.

If you've had oral or anal sex in addition to vaginal sex, it might be wise to test not only urine but also include the throat or anus.

When do you choose a throat test?

A throat test may be necessary if you've had oral sex. Chlamydia and gonorrhea can also occur in the throat. This is not always detected with a standard urine test.

A throat test may be appropriate for:

unprotected oral sex;
unprotected fellatio or cunnilingus;
sore throat after sexual contact;
sexual contact involving the mouth;
contact with someone who tested positive for chlamydia or gonorrhea.

An STI in the throat does not always cause symptoms. Therefore, you might have an infection without realizing it. That's why it's important to choose the correct testing site.

When do you choose an anal test?

An anal STI test may be necessary if you've had anal sex. Even if you don't have symptoms, an infection may be present in the anus.

An anal test may be appropriate for:

unprotected anal sex;
itching, pain, or irritation around the anus;
discharge or blood from the anus;
had anal sex, even without symptoms;
a sexual partner who tested positive for chlamydia or gonorrhea.

If you only test urine after anal sex, an infection in the anus might be missed. Therefore, choose a test that matches the contact you've had.

Can you have an STI without symptoms?

Yes, that's possible. Many STIs don't always show clear symptoms. So you can have an STI without experiencing pain, itching, discharge, or other symptoms.

Possible symptoms of an STI include:

pain or burning sensation when urinating;
discharge from the penis, vagina, or anus;
pain, itching, or irritation;
sores, blisters, or warts;
bleeding after sex;
sore throat after oral sex.

So, no symptoms does not automatically mean there is no STI. Have you had unprotected sex or are you unsure? Then testing might be wise.

How long should you wait to get tested?

After sexual contact, an STI is usually not immediately detectable. This is called the incubation period or waiting period. If you test too early, the result may be unreliable.

For chlamydia and gonorrhea, it is often recommended to test approximately 14 days after the potential exposure. For other STIs, such as HIV or syphilis, different waiting times may apply.

Which STI test is right for your situation?

Which STI test you need depends on the type of sexual contact you've had. Below you'll find a simple decision aid.

Situation	Possible test
Unprotected vaginal sex	Chlamydia & Gonorrhea genital
Unprotected oral sex	Chlamydia & Gonorrhea throat
Unprotected anal sex	Chlamydia & Gonorrhea anal
Multiple partners or broader check	Complete STI test
Doubt about HIV or syphilis	Test kit with HIV and syphilis

Is a urine test alone enough?

Testing only urine is not always enough. It depends on where the potential risk occurred. If you've only had vaginal sexual contact, a urine test may be sufficient. But with oral or anal sex, an additional throat test or anal test may be necessary.

The main rule is simple: test at the site where sexual contact occurred.

Frequently Asked Questions

Can I test for an STI in my throat with urine?

No, a urine test does not detect STIs in the throat. If you've had oral sex and want to check your throat, you need a throat test.

Can I test for an anal STI with urine?

No, a urine test does not detect an infection in the anus. If you've had anal sex, an anal test is needed to check that area.

Do I need an STI test if I don't have symptoms?

Yes, that can be wise. An STI doesn't always cause symptoms. If you've had unprotected sex or are unsure, testing can provide clarity.

When should I test after unsafe sex?

For chlamydia and gonorrhea, approximately 14 days after the exposure is often recommended. For other STIs, different waiting times may apply. Therefore, always check carefully when you can reliably test.

Which test do I need after oral and anal sex?

In that case, it may be advisable to test both the throat and the anus. If you've also had vaginal or penile contact, a genital test may also be necessary.
