HHV6 Test Results

My HHV6 Ab Igg came back 1:1280. This is really high, right?

IgG is long term antibodies, so it does mean you didn't acquire the infection very recently. And according to http://www.hhv-6foundation.org/research/hhv-6-testing:

Elevated IgG antibody levels can suggest, but not prove active, chronic infection. In a 1996 study of HHV-6 in CFS patients, 89% of the patients with IgG titers of 1:320 and above were found to have active infections by culture. (Wagner, Journal of Chronic Fatigue Syndrome)Stanford infectious disease specialist Jose Montoya believes that the best evidence of smoldering central nervous system (CNS) infection is the IgG antibody to the virus, and not the virus itself. In a pilot study, he found that when patients with high titers of HHV-6 IgG (1:320, 1:640 or higher) and EBV are treated with a potent antiviral; their titers fall substantially along with a significant improvement in symptoms. Elevated IgG Antibodies to HHV-6 cannot indicate with certainty that the infection is active, but high titers support a clinical diagnosis.

You're well above 1:320, so treating for chronic active viral infection might make you feel better
