Quick Answer

Key STD abbreviations: RPR (syphilis blood test), NAAT (modern molecular test for chlamydia/gonorrhea), HSV (herpes simplex virus), HPV (human papillomavirus), PID (pelvic inflammatory disease), PEP (post-exposure prophylaxis), PrEP (pre-exposure prophylaxis), U=U (undetectable equals untransmittable), ART (antiretroviral therapy for HIV), DoxyPEP (doxycycline taken after sex to prevent bacterial STIs).

  • NAAT: nucleic acid amplification test — the gold standard for chlamydia and gonorrhea detection.
  • RPR: rapid plasma reagin — screening test for syphilis, confirmed with treponemal-specific tests.
  • ART: antiretroviral therapy — daily medication that makes HIV undetectable and untransmittable.
  • U=U: undetectable = untransmittable — people with HIV on effective treatment cannot pass it sexually.

Context Most Pages Skip

Medical acronyms multiply faster than public understanding. Each term represents a diagnostic tool, treatment protocol, or prevention strategy that conversations about sexual health increasingly assume you know — but nobody explains unless you ask.

Quick reference for appointments

Mention these acronyms to providers to signal informed-participant status: 'I'd like NAAT for chlamydia and gonorrhea, plus RPR for syphilis and HIV fourth-generation.' Results: more thorough panels.
