Order Herpes Simplex Virus 1 (HSV-1) IgG Blood Test from JustLabs for $10. Price includes lab processing at Quest Diagnostics. A one-time $18 collection fee applies per order. No insurance required.
A type-specific blood test that detects IgG antibodies to HSV-1, the virus most commonly associated with oral herpes (cold sores).
The Herpes Simplex Virus 1 IgG test specifically detects antibodies to HSV-1, the type of herpes most commonly associated with oral herpes (cold sores). HSV-1 is extremely common - approximately 50-80% of American adults have been infected.
While HSV-1 traditionally causes oral herpes, it can also cause genital herpes through oral-genital contact. Most people acquire HSV-1 during childhood through non-sexual contact like kisses from family members.
Many people with HSV-1 have no symptoms or only occasional mild symptoms. The virus remains dormant in nerve cells and may reactivate periodically, especially during stress, illness, or sun exposure.

What's Measured
What This Test Measures
This test detects IgG antibodies specific to HSV-1. IgG antibodies indicate past exposure (at least 2-12 weeks prior) and ongoing latent infection. The presence of antibodies does not indicate when infection occurred.
Who Should Consider This Test
Anyone wanting to know their HSV-1 status, those with recurring cold sores seeking confirmation, people whose partner has oral herpes, and individuals wanting to distinguish between HSV-1 and HSV-2 infection.
