Cheapest same-day STD test
For most people in a US metro, the lowest-cost same-day option is a cash-pay order at a national reference lab (Labcorp or Quest), or a free walk-in at a public health STI clinic. “Same-day” usually means the sample is collected today; results typically arrive in 1–3 days.
Short answer
- Cheapest paid: Labcorp OnDemand chlamydia + gonorrhea panel from ~$39. Order online, walk in to a Labcorp draw site today.
- Cheapest free: public health STI clinic (e.g., SF City Clinic, NYC Sexual Health Clinics, LA County DPH). Walk-in availability and what’s offered varies — verify with the clinic.
- Same-day result options are limited: rapid HIV antibody testing is widely available (~20-min results) at many city clinics. Most other STI tests use lab analytics with 1–3 day turnaround.
- If you have symptoms or a recent high-risk exposure, see a clinician same-day — routine cash-pay screening isn’t the right path for an active issue.

What “same-day” actually means
- Sample collection: usually same-day if you walk into a Labcorp/Quest patient service center or a public clinic.
- Results: rapid HIV antibody testing can return ~20-minute results at many clinics. Most other STI testing uses NAAT or serology with 1–3 day turnaround.
- If you need treatment: a positive result usually requires a clinician follow-up. Plan for that step before testing.
When cheap isn’t the right metric
If you have active symptoms (discharge, sores, painful urination, pelvic pain) or a recent high-risk exposure, going to a clinician same-day matters more than getting the cheapest test. Symptoms can mean an active infection that needs treatment now, and an emergency room or urgent care — even at higher cost — will both diagnose and treat in one visit. Cash-pay routine screening is a fit for asymptomatic, lower-urgency situations.
