For most sexually transmitted infections, men get tested through a simple urine sample or a blood draw. The specific tests depend on which infections are being screened for, but a standard panel typically covers chlamydia, gonorrhea, syphilis, and HIV. The whole process is straightforward and usually takes less than 30 minutes at a clinic.
What a Standard STI Panel Covers
A routine sexual health screening for men checks for the most common infections: chlamydia, gonorrhea, HIV, and syphilis. Depending on your risk factors and sexual history, your provider may also test for hepatitis B, hepatitis C, and herpes. All adults over 18 should be screened for hepatitis C at least once. Men who have sex with men should be tested at least once a year for syphilis, chlamydia, gonorrhea, and HIV, along with hepatitis B.
If you have HIV, screening for additional infections like syphilis, gonorrhea, herpes, and chlamydia is typically part of your regular care since co-infection risk is higher.
The Urine Test
Chlamydia and gonorrhea are the two infections tested through a urine sample. You urinate into a cup, and the sample is sent to a lab for nucleic acid amplification testing, which detects genetic material from the bacteria. It’s highly accurate when the sample is collected properly.
The one preparation step that matters: don’t urinate for at least one hour before collecting your sample. This gives enough time for bacteria to accumulate in the urethra so the test can detect them. If you empty your bladder right before the test, you risk a false negative.
The Blood Draw
HIV, syphilis, hepatitis B, and hepatitis C all require a blood sample. A phlebotomist draws blood from your arm into one or more tubes. About 1 milliliter of serum is enough to run both syphilis tests, so the total blood needed across all tests is modest.
Herpes testing, when included, also uses a blood sample. A type-specific blood test can identify whether you carry HSV-1, HSV-2, or both. This test is most useful if you’ve had recurring or unusual genital symptoms without a clear diagnosis, or if a partner has genital herpes. Routine herpes blood testing isn’t standard for everyone, but your provider may recommend it if you have multiple sexual partners.
When Swabs Are Needed
A urine test only detects chlamydia and gonorrhea in the urethra. If you’ve had oral or anal sex, infections at those sites won’t show up in urine. Throat and rectal swabs use the same detection technology as the urine test but collect samples directly from the exposure site.
Rectal and throat swabs are specifically recommended for men who have sex with men, people involved in sex work, known contacts of someone with chlamydia or gonorrhea, and anyone with symptoms like rectal pain or a persistent sore throat after oral sex. Even outside these groups, your provider may recommend site-specific testing based on your sexual history. The swabs are quick, and self-collection (where you do the swab yourself) is an option at many clinics.
The Physical Exam
Some infections can’t be caught by blood or urine tests alone. Genital herpes during an active outbreak is diagnosed by examining and swabbing the sores directly. Genital warts caused by HPV are identified visually. During a physical exam, a clinician looks for small bumps, blisters, open sores, or ulcers on the genitals, anus, thighs, or mouth. Swollen lymph nodes in the groin can also signal an active infection.
If you notice any unusual sores, bumps, or discharge between screenings, getting examined while symptoms are present gives the most accurate results. Herpes sores in particular are easiest to test when blisters are fresh rather than already healing.
At-Home Testing Kits
Mail-in STI kits let you collect samples at home (typically urine and a finger-prick blood spot) and send them to a lab. The lab technology behind these kits is generally reliable. The weak link is sample collection. Without a trained professional guiding the process, there’s a higher chance of collecting a poor sample, which can lead to false negatives where an infection goes undetected, or false positives that flag an infection that isn’t there.
Labs affiliated with hospitals, medical systems, or public health departments tend to have more rigorous quality control. At-home kits work well as a first step if getting to a clinic is a barrier, but if your results come back positive or if you have symptoms that don’t match a negative result, in-person follow-up testing is worth the trip.
How Often to Get Tested
There’s no single schedule that fits everyone. Sexually active men with multiple partners or who don’t consistently use condoms should test regularly, with the exact frequency based on risk level. Men who have sex with men face the highest statistical risk for several STIs and should screen at least annually for the core panel of chlamydia, gonorrhea, syphilis, and HIV. More frequent testing (every three to six months) is common for men with higher numbers of partners.
If you’re in a new relationship, both partners testing before stopping condom use gives a clear baseline. After a known exposure or a condom failure, testing should account for the window period of each infection. HIV and syphilis may not show up on a blood test for several weeks after exposure, so testing too early can miss a recent infection.
Beyond STIs: Prostate Cancer Screening
If your search was broader than sexual health, prostate cancer screening is another common testing question for men. The PSA test is a blood test that measures levels of a protein produced by the prostate. Men between 55 and 69 should have a conversation with their doctor about whether PSA screening makes sense for them, weighing the benefits of early detection against the possibility of unnecessary follow-up procedures. The U.S. Preventive Services Task Force recommends against routine PSA screening for men 70 and older. These guidelines apply regardless of whether you’re at average or increased risk, as long as you don’t have symptoms and haven’t been previously diagnosed.
