At-home STI testing

At-home testing splits into two very different models: mail-in kits, where you post a sample to a laboratory, and instant tests, where the test runs where you are. Diagnik only sells instant tests.

At-home STI testing

What instant testing means in practice

  • You collect the sample — gum swab, fingerstick or vaginal swab.
  • The test runs in 15 to 40 minutes depending on the test.
  • You read your own result from the instruction card.
  • No sample leaves your home and no result is transmitted anywhere.

What it is genuinely good at

  • Answering a specific worry quickly, without an appointment.
  • Removing the conversation barrier for people testing for the first time.
  • Privacy — plain packaging, guest checkout, no stored results.

Its honest limits

  • Screening only. Reactive results need clinical confirmation.
  • Timing-sensitive: testing inside a window period can miss an infection.
  • Site- and anatomy-specific: no throat or rectal testing, and no instant chlamydia or gonorrhea option for people with a penis.

Are at-home STI tests accurate?
FDA-authorized over-the-counter tests are reliable screening tools when used exactly as instructed and outside the window period. Reactive results are confirmed clinically.
Do I have to post anything?
No. Every test Diagnik sells is read at home; nothing is mailed to a laboratory.
