- Listings that name fewer than three tests are left outEven on GetTested, 527 listings name fewer than three tests. We don’t show them anywhere.
- Unverified pregnancy centers are never shownThe CDC lists some pregnancy centers whose STD testing we couldn’t verify. We don’t list them anywhere.
- Cost is stated the way the CDC lists itFree, sliding scale or insurance accepted, as each clinic reports it to the CDC. We don’t estimate prices, and if the listing says nothing, the card says “Fees not listed.”

There were 98 new HIV diagnoses in Montgomery 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.
Montgomery County reported 4,068 chlamydia cases in 2023, a rate of 384.3 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
A test result is the start, not the end. If you are negative and want to stay that way, PrEP and DoxyPEP cut the risk of a future infection. If you are positive, most STIs can be treated without setting foot in a clinic. Both are available to people in Gaithersburg by video visit, prescribed by clinicians licensed in Maryland.
