Common STI Tests: A Field Guide
Common STIs and the tests used to screen for them, in plain language. Each row covers what the infection is, relevant timing or specimen notes, and a link to order. Trichomoniasis is another infection people may ask their clinician about; it is not listed here because no order page is currently available for it.
Chlamydia
Chlamydia can be asymptomatic, meaning it may be present without noticeable symptoms. Testing options and specimen type can vary.
Gonorrhea
Gonorrhea can be asymptomatic. This test is often ordered alongside chlamydia because the two infections share similar risk factors. Testing options and specimen type can vary.
HIV
Testing timing matters. A negative result soon after a potential exposure may not rule out a recent infection. If you have questions about timing, consult a clinician.
Syphilis
Early syphilis may not cause obvious symptoms. Testing timing can affect results. Testing options can vary.
Herpes (HSV-1 and HSV-2)
Important note: Blood antibody testing for HSV is not recommended for everyone and should be discussed with a clinician, especially if symptoms or recent exposure are involved. Whether to seek HSV testing and which type is a decision that benefits from clinical context.
HPV
HPV testing context varies by sex, age, screening history, and collection method. This is an area where talking to a clinician first is especially useful.
Mycoplasma Genitalium
Mycoplasma genitalium is not included in standard STI panels and may not be on the radar of every clinician. If relevant, it can be ordered as a standalone test.
STD Panels
STD panels group multiple tests into a single order. The Expanded STD Panel covers more infections; the Basic STD Panel focuses on the most commonly tested. Panels may be more convenient or economical depending on what someone is considering, though specific coverage and pricing can vary.
Considering a panel?
Panels group multiple tests into a single order, which can be more convenient or economical depending on what someone is considering. Specific coverage and pricing can vary, so it is worth reviewing what each panel includes before ordering. The Expanded STD Panel covers a broader set of infections. The Basic STD Panel focuses on the most commonly tested.
Testing options, availability, specimen type, and timing can vary. If you have symptoms, a known exposure, a positive result, or are pregnant, contact a licensed healthcare professional rather than relying on a consumer lab order alone.
