The index value of the HSV1 was 2.42 as of 6/11 (the last test I did). The PCR in 2018 picked up HSV2, not HSV1. I did blood testing at that time and that said I was positive for HSV2 and negative for HSV1. Now I’m positive for HSV1 and not HSV2 per blood test results. I’m confused how now I’m “positive” for HSV1 but not HSV2.
Will being off of valtrex for 1-2 weeks make a difference? I’m waiting on the western blot test to arrive.
What are the chances of the HSV1 being a false positive?
In 2018 when I was assaulted, I was tested by a PCR swab and blood test about a week after the assault when the symptoms/outbreak was unbearable. Both of them came back positive for HSV2 and not HSV 1. I have taken the valtrex (500 mg) and l lysine everyday since the assault. I’ve never passed it on to anyone. How long should I be off of valtrex for when I do the western blot test? Do you think the conflicting results could be a cross reaction? I want to say the HSV1 is a false positive but am VERY confused why that came up positive when it was negative for years and HSV2 was positive with the blood test and swab which is 99.99% accurate.
Have you seen this happen in your experience?
Thank you for the reply! I have not had another outbreak since 2018. I have never had a cold sore either. I take 500 mg of valtrex daily along with L Lysine. Do I need to be off of that for when I do the western blot test? Do you think the HSV1 test was a false positive? Why would the most recent blood tests pick up HSV1 and not 2 when the PCR swab picked up HSV2? Could it be a cross reaction? The IGG was 2.42 both times and I know that’s within the false positive range. Any idea what happened?

Could the HSV1 be a false positive? Why did I test positive for HSV1 and not 2 recently when the swab test (4.5 years ago) was positive for HSV2 and not HSV1?
