About this test
The common 4 is a bundle of four tests: chlamydia, gonorrhea, syphilis and HIV. They match the core of CDC's screening advice. CDC recommends an HIV test at least once for everyone aged 13 to 64, and yearly chlamydia and gonorrhea tests for sexually active women under 25. It says most sexually active adults should test for syphilis based on where they live. For gay, bisexual and other men who have sex with men, it recommends all four at least once a year.
The bundle usually needs blood for syphilis and HIV, and urine or a vaginal swab for chlamydia and gonorrhea. If you had oral or anal sex, check whether throat and rectal swabs are included, because urine doesn't test those sites.
All four infections are reportable in every state, so positive results go to the health department, which keeps them confidential.
If you've never been tested for hepatitis B or C, CDC recommends both for all adults at least once. Some full panels include them.
When to test
The four tests have different windows. Chlamydia and gonorrhea tests match CDC's timing from about 2 weeks after exposure. CDC suggests syphilis tests at 4 to 6 weeks, and a lab HIV antigen/antibody test can usually detect HIV 18 to 45 days after exposure. A test about 45 days after exposure covers all four with lab tests. CDC's sexual assault guidance repeats syphilis and HIV tests at 3 months.
Retesting
CDC recommends retesting about 3 months after treatment for chlamydia or gonorrhea. For routine screening, many people test once a year. CDC suggests every 3 to 6 months for men who have sex with men at increased risk.
Common questions
What's in the common 4?
Chlamydia, gonorrhea, syphilis and HIV. Together they match the core of CDC's routine screening advice for most sexually active adults.
Is the common 4 enough?
For many routine checks, yes. CDC also recommends a hepatitis C test and a hepatitis B test at least once for every adult. If you've never had those, consider a full panel that includes them.
Can I take the common 4 at home?
Some home kits cover all four, using finger-prick blood for syphilis and HIV and urine or a swab for chlamydia and gonorrhea. A lab visit uses blood from a vein, which allows the HIV test with the shortest window.
Will the results be reported?
Positive results for all four are reported to the health department in every state, including for tests ordered online. CDC says these reports are kept confidential.
