False-Positive Serum DNA-PCR

Is it possible to get a false-positive for HSV2 on a serum (blood test, no active lesions ever so no swab) only DNA-PCR exam, specifically if an IgG test that followed 6 months later showed no sign (not even weak positive) for HSV2 and only positive results for HSV1?

That test is for a active lesion or spinal fluid. The test is no use for blood. this was an error to order it bottom line. If you concerned you have herpes then the igg type specific is the one or the Western blot.

Makes sense. It's so annoying. I've read how a negative DNA-PCR serum/blood test is a waste but nothing about a positive result. I will definitely be calling my insurance company to complain. Thanks so much!

Thanks so much! So even a positive result is of no use? It is just all very confusing as it differentiated and listed that HSV2 was "detected" (the DNA PCR serum/blood test results) but the IgG specific test I had done months after showed only the HSV1 that I know I have antibodies to. It is also confusing because I have not been active for years so there would have been no way to contract HSV2.

The pcr blood test for herpes is not of any use. the provider erred in ordering this. Sorry some times i dont get a chance to read in detail. I read the first test was igg specific.

Well the DNA-PCR exam did not come with values, just the "detected" response. The doctor's office called the lab and there were apparently no values. It was not the standard IgG antibody test but the PCR test with blood and not a swabbed sample.

Hi, yes it is if your positive was a low positive the first time around. Usually a second test is advised then it is. Do you know what your first number was?
