Quick Verdict
For HSV testing, lab-based blood IgG tests via STDCheck are more accurate than true home kits. Mail-in fingerprick kits are a reasonable option when lab visits are not possible. Home swab kits should be avoided — they only detect active outbreaks.
Quick Answers
- Home swab kits: only detect active outbreaks — useless for asymptomatic screening
- Blood IgG test: detects HSV regardless of symptoms — the correct screening test
- STDCheck blood IgG: $45, 4500+ Quest locations, results in 24-48hr
- True home kit: LetsGetChecked fingerprick mail-in at $99
- Window period: IgG detectable 12-16 weeks after infection — test at 12 weeks

The Critical Distinction Most People Miss
When people search for an at-home herpes test, they usually imagine a kit they collect at home and mail in. This exists. But the correct question is: which approach accurately detects HSV regardless of whether you are having an active outbreak? The answer is a blood IgG antibody test — and understanding this distinction will save you from acting on a meaningless result.
HSV Swab Tests: Limited Usefulness
A swab test collects cells from a visible sore and detects HSV DNA via PCR. This works well for diagnosing an active outbreak. It does not work for screening — if there is no active sore to swab, the test cannot detect HSV in your body. Since most HSV-positive people have no symptoms, a swab kit bought on Amazon will return negative for almost everyone using it without an active outbreak, regardless of their actual HSV status.
Blood IgG Testing: The Correct Approach
After HSV infection, your immune system produces IgG antibodies that remain in your bloodstream permanently. A blood IgG test detects these antibodies regardless of whether you have ever had a visible outbreak. For HSV-2, the HerpeSelect IgG test used by STDCheck has approximately 96% sensitivity and 97% specificity after the 12-16 week window period.
STDCheck: Lab-Accurate, Near-Home Convenience
STDCheck requires a brief visit to one of 4,500+ Quest Diagnostics locations — no appointment needed. The blood draw takes under 5 minutes. Results arrive in 24-48 hours with full privacy. At $45 for HSV-2 this is the most cost-effective route to genuinely accurate herpes screening.
True At-Home Option: LetsGetChecked
LetsGetChecked offers a mail-in fingerprick blood test for HSV IgG at $99. A kit arrives discreetly. You prick your finger, collect blood on a card, and mail it back pre-paid. Results in 2-5 days. Accuracy is slightly lower than a venous blood draw due to sample variability — positive results should be confirmed with a clinical test.
Frequently Asked Questions
How accurate is the LetsGetChecked herpes test?
LetsGetChecked uses IgG antibody testing on a fingerprick blood sample. Accuracy is slightly lower than a venous blood draw due to sample collection variability. Positive results from LetsGetChecked should be confirmed with a clinical venous blood test.
Can you test for herpes without a blood draw?
Not accurately for screening. Swab tests only detect active outbreaks. Blood testing — either fingerprick mail-in or venous lab draw — is the only accurate method for asymptomatic screening.
When should I test for HSV after a potential exposure?
Wait at least 12 weeks from the most recent potential exposure. IgG antibodies become detectable in most people within 12-16 weeks. Testing earlier may produce a false negative even if infection occurred.
