Herpes 1 Hsv-1 Test
This HerpeSelect® test looks for the specific antibodies that fight the herpes simplex 1 virus (HSV-1) in your blood. HSV-1 typically causes oral herpes, but.

What is the Herpes 1 Hsv-1 Test?
The Herpes 1 Hsv-1 Test screens for a sexually transmitted infection using modern laboratory methods.
How the Herpes 1 Hsv-1 Test works
Depending on the infection, testing uses either a small blood sample (for HIV, syphilis, hepatitis, herpes antibodies) or a urine sample/swab amplified with NAAT (nucleic acid amplification), the most sensitive method for chlamydia and gonorrhea.

Why healthcare providers order it
STI testing is recommended for anyone sexually active with new or multiple partners, during pregnancy, before starting PrEP, when a partner is diagnosed, or whenever symptoms appear. Many infections are silent — routine screening catches them before complications and onward transmission.
Interpreting your results
Understanding STI test results
- Negative / non-reactive: no evidence of infection — but respect window periods: each infection has a span after exposure during which tests may not yet detect it. Retesting after the appropriate interval is standard practice after a known exposure.
- Reactive / positive: requires professional follow-up. Confirmatory testing applies to HIV and syphilis screens. Treatment exists for every bacterial STI here, and partner notification/treatment prevents reinfection.
- Equivocal: repeat per protocol.
CDC-recommended screening intervals apply regardless of symptoms for sexually active people under 25 and others at increased risk.
Reference intervals vary by laboratory, instrument, age, sex, and — for hormones — collection time. Always compare your value against the range printed on your own report, and review results with a qualified healthcare professional who knows your history. This guide is educational and does not diagnose.
Understanding your lab report
- Find the reference interval printed beside your value on the report — that pairing defines 'normal' for this lab run.
- Note the units. mmol/L vs mg/dL, ng/mL vs µg/L — numbers mean nothing across unit systems.
- Look at flags (H/L) but read the degree: barely-outside values behave differently than multiples of the limit.
- Trends outrank snapshots. A series of results tells your provider far more than any single draw.
Frequently asked questions
What does the Herpes 1 Hsv-1 Test measure?
It looks for direct molecular evidence of the infection or the antibodies your body produces against it.
Do I need to fast before the Herpes 1 Hsv-1 Test?
Fasting is not routinely required for this test; follow any instructions from your provider or laboratory.
How soon do Herpes 1 Hsv-1 Test results come back?
Most routine assays return within 1–3 business days; specialty methods can extend that to a week or more.
Can an abnormal Herpes 1 Hsv-1 Test result mean something serious?
Most infections covered here are curable or manageable, and a reactive result warrants prompt professional follow-up plus partner notification.
How soon after exposure will the Herpes 1 Hsv-1 Test detect infection?
Every infection carries a 'window period' before tests turn reliably positive — days for gonorrhea/chlamydia NAAT, roughly 2–6 weeks for syphilis and combination HIV assays. Testing immediately after a known exposure misses early cases, so scheduled repeat testing is the standard advice.
