Same-Day STD Testing: Walk-In and Rapid Testing Options

Updated 2026-11-04

Same-day STD testing usually means one of two things: a clinic that sees you without an appointment, or a rapid test that gives a result during the visit. Not every infection has a rapid test, so some results still take a few days.

Options for same-day testing

Clinics that don't require an appointment. Our directory has no separate "walk-in" field, but the CDC NPIN data marks whether an appointment is required. 2,242 locations say no appointment required. Hours and walk-in slots can be limited, so call first.
Rapid HIV tests. 5,537 locations list rapid HIV testing. HIV.gov explains that with a rapid finger-prick or oral-fluid test "you may be able to wait for the results."
At-home self-tests. CDC says FDA-approved self-tests exist for HIV and syphilis, and a self-test for gonorrhea, chlamydia and trichomoniasis using a vaginal swab. HIV.gov says an HIV self-test gives results within 20 minutes.
Online-ordered lab tests. Some companies let you order online and visit a partner lab without an appointment; results typically take a few days. See published prices.

Timing matters

A test taken too soon after exposure can miss an infection. HIV.gov notes that the HIV window period can be 10 to 90 days depending on the test, and you may need to retest after it. If you think you were exposed to HIV in the last 72 hours, HIV.gov advises talking to a health care provider as soon as possible about PEP.
