Sexually active women under 25 should be tested for gonorrhea and chlamydia every year

Why it matters

Many sexually transmitted infections cause no early symptoms and spread unnoticed; CDC states that most STIs have no signs or symptoms. Condoms reduce transmission risk, while testing makes treatment and partner care possible. CDC recommends yearly gonorrhea and chlamydia testing for sexually active women under 25, and testing early in every pregnancy for syphilis, HIV, hepatitis B and hepatitis C.

How to do it

  1. Use condoms correctly throughout sex when there is a risk of infection.
  2. Discuss STI testing with a clinician, including which sites need samples based on the kinds of sex you have.
  3. If you are a sexually active woman under 25, ask for yearly gonorrhea and chlamydia testing.
  4. If a test is positive, complete treatment and follow advice on partner care and when sex can resume.
  5. During pregnancy, arrange the recommended infection tests early in antenatal care.

Condoms do not eliminate every STI risk. Symptoms, pregnancy or a recent possible HIV exposure need prompt clinical advice; testing timing matters.

Do it

Pick the time you have. Anything beats nothing.

Start with the time you have

1 minute

Prepare this question for a sexual health service: which tests and sample sites fit the sex I have, and when should I test?

In real life

  • Ask whether you need throat or rectal samples as well as urine or blood tests, based on the sex you have.
  • Before sex with a new partner, discuss testing and using condoms together.

Watch out for

  • Common mistakeNo symptoms does not mean no infection, so ask which tests suit your situation.
  • Common mistakeOne test does not cover every infection or body site, so describe your exposures when arranging testing.
