Testing privacy

Anonymous vs. confidential testing

Most clinics test confidentially. Some also offer anonymous testing, usually for HIV. Availability varies by testing site, so ask when you call.

Confidential

  • You give your name, and the result goes in your medical record.
  • Results are not available to the public.
  • Chlamydia, gonorrhea, syphilis and HIV are reportable in every state, so a positive result is reported to the health department. Those reports are kept confidential.

Anonymous

  • You don’t give your name.
  • You receive a number and use it, not your name, to get your result.
  • Not every site offers it. Ask before your visit.

There were 11 new HIV diagnoses in Douglas County in 2023. HIV is the one infection where how soon you test changes which test you need — an RNA test detects it far earlier than a standard antibody test.

Douglas County reported 717 chlamydia cases in 2023, a rate of 186.8 per 100,000 residents. Most people who have chlamydia or gonorrhea have no symptoms at all, so waiting for something to feel wrong is not a strategy.

HIV prevention & treatment

PrEP, DoxyPEP & Online Treatment
