Get tested for past infection

This is a serology test (also known as an antibody test), and therefore requires a blood draw. The test will determine if you had a past infection.

By Appointment Only

Serology testing is by appointment only. We cannot accept walk-ins.


Testing will be conducted at 3444 Valle Verde Dr, Napa, CA 94558.
