The FREE home test kit that is currently offered includes a vaginal swab that tests for vaginal chlamydia and gonorrhea infections. The program is currently available to young women, girls, transmen, and any person with a vagina between the age of 12-30 in San Francisco County who is sexually active or has had sex in the past. The kit is best for people who want to test at home instead of going to a clinic. If you are having symptoms of an STI or if you are pregnant DO NOT ORDER THE KIT, instead go to a doctor or clinic right away to get checked.

when to test icon

Per the Centers for Disease Control and Prevention (CDC) recommendations, sexually active women age 24 years or younger should be tested for chlamydia and gonorrhea every year.  CDC also recommends getting tested if:

  • you have symptoms
  • you change sex partners
  • you have more than one sex partner
  • your partner has more than one sex partner

You should also be re-tested 3 months after you finished treatment for either a chlamydia or gonorrhea infection.

why test icon

Anyone who has had unprotected sex or had a condom break during sex can get chlamydia or gonorrhea. Most people who have chlamydia or gonorrhea will not know it because they will not have any signs or symptoms. These STIs can be treated with the right medicine. However, it’s important to get regular testing and early treatment. If these STIs are not treated, they can cause permanent damage to your reproductive organs.  This can lead to lasting pain and may make it difficult to get pregnant.
