STIs: Testing, Treatment, and What Actually Needs Follow-Up
The CDC estimates roughly 1 in 5 people in the US has an STI at any given time — this is common, not rare, and most are either curable outright or manageable with treatment. The bigger practical issue is that "I got tested" often means something narrower than people assume, and knowing what a panel actually covers changes what you should ask for.

What a standard STI panel actually tests for
"Get tested for everything" isn't automatic. A standard panel typically covers chlamydia, gonorrhea, syphilis, and HIV. Herpes and HPV usually aren't included unless you have symptoms or specifically ask — herpes because blood antibody testing has a meaningful false-positive rate and isn't recommended for routine screening without symptoms, and HPV because it's tested differently (as part of cervical screening, not a blood or swab STI panel). If you want a specific infection checked, say so directly rather than assuming a general request covers it.
Curable vs. manageable — a real distinction
Chlamydia, gonorrhea, syphilis, and trichomoniasis are bacterial or parasitic and curable with antibiotics. Herpes, HIV, and HPV are viral — herpes and HIV are managed long-term rather than cured, and HPV, notably, is cleared by the immune system within about two years in the large majority of cases without any treatment at all. Knowing which category applies to your specific result matters for how you think about it going forward.
Why "no symptoms" doesn't mean "no infection"
Chlamydia and gonorrhea are frequently asymptomatic, especially in women — which is exactly why routine screening (testing on a schedule, not just when something feels wrong) is recommended for sexually active people under 25 and anyone with new or multiple partners, rather than waiting for symptoms to prompt testing.
Window periods — timing matters
Tests can't detect an infection immediately after exposure — there's a window period before it becomes detectable, which varies by infection and test type (HIV testing, for example, has different window periods depending on whether it's an antibody, antigen/antibody, or RNA test). If you're testing right after a specific exposure, ask your provider what the appropriate window is and whether a repeat test later is needed.
Partner treatment matters as much as your own
If you test positive for a curable infection, your partner(s) need treatment too, or reinfection is likely. Expedited partner therapy — where you're given a prescription or medication to deliver to a partner without them needing their own appointment first — is a legal, standard option in most states specifically to reduce this barrier.
When to seek care urgently
Untreated chlamydia or gonorrhea can progress to pelvic inflammatory disease (PID) — fever, worsening pelvic pain, and pain with intercourse are signs worth same-day evaluation, since PID can affect future fertility if it goes untreated further.
