What Is a Herpes Blood Test?
Herpes blood tests detect antibodies — not the virus itself.
Types
- Type-specific IgG — preferred
- Non-type-specific — not recommended
- Viral culture — swab of active sore
- PCR — viral DNA from swab
When Accurate
- 4–6 weeks after exposure
- May not detect recent infection
Limitations
- Cannot tell location (oral vs genital)
- Cannot tell when infected
- Low-positive may need confirmation
