Q: Causes of false positive herpes test result?

Are there medical conditions/diseases that can cause a false positive test result?

I have an autoimmune condition and small fiber neuropathy.  I have never had a positive viral culture but have had a positive hsv-2 blood test.

usually once your postive your positive. I would retest again in a few months. If it turns up postive again then im sorry hun but your positive.

Sorry, but your wrong. If you get a blood's not accurate. 30% can have false negatives. 30% percent can also have false positives. To get a accurate result you have to get a swab test during an outbreak

Are you sure of that?  Can there really be false positive herpes test?  I have never had any outbreaks or signs, was tested for it (blood test) and they said it was positive.  So, I've been on acyclovir for 2 years and thinking maybe they were wrong. Could they have been?

I too have never had an outbreak or sore...ever...I came up positive also. But since I never had an outbreak or a sore my Dr. has never prescribed me any medicine. And two years later, still no outbreak. I had 8 blood transfusions years ago and this was my cause. Have been married for 11 years and my husband has always tested negative. I too have neuropathy and Trigeminal Neuropathy and my Dr. thinks it might stem from that. But no one truly knows the answer yet. But one day they will like always.

I also have various autoimmune disorders, and I reached this site looking for illnesses that could cause a false positive herpes blood result. I know I have never had a break out, sores I have had have been cultured and come back negative for herpes. I now know that I have discoid Lupus amongst other things, so could this be an early detection that no one knows about yet?

I've also had a couple of false positive lyme tests, and I have had at least 10 of them since all this started a couple of years ago.

I wish there were more answers out there for people like us.

What can cause a false positive herpes and a false positive lyme?

does any one have an idea?
