Because most herpes outbreaks are short and mild, and because most people have few, mild or even NO outbreaks, we highly recommend taking a herpes blood test when no active sores or lesions are present, and in ADDITION to a Herpes Lab Culture when there is a sore present.
A PCR (Polymerase Chain Reaction) test can be done on cells or fluid from an active sore and is more sensitive than typical lab culture tests.
The best way to diagnose herpes when you are not having symptoms is to request a herpes blood test.
And sometimes your doctor will even push back and tell you that you don’t need a Herpes Blood Test or give you another reason why they don’t want to give you a Herpes Blood Test.
But medicine has made great strides, and since 1999, there are several NEW Ig G blood tests now available that DO very accurately distinguish between HSV-1 and HSV-2 and are 97-100% ACCURATE, if taken no earlier than 12-16 weeks after your possible exposure to the virus.
