False positive PCR

[Anon2022OR]

Hi!
Thank you for having this forum. I was sexually assaulted by a trans male (he doesn’t have a penis and used a strap on) in September and the person who did it apparently has HSV1. A few days after it happened I went to URGENT CARE to get tested for everything because I was terrified. I had no symptoms. Pure precaution. I noticed in the office that I had a canker sore in my cheek. Something that I recognized and 100% know is a canker sore since I have been getting them all my life. I only get them in my mouth..never on my lip. I get them more frequent when my B12 is low. Anyway. He swabed the small canker sore because I made him out of pure anxiety and peace of mind. I later got the result of HSV2. He said that it was “positive” and did not have an index value. He also said that I shouldn’t kiss my dog because of spread (insight to this doctor)I started to think I had HSV2 all along however my IGG blood came back negative. I took ten days of Valtrex when I was diagnosed and then another 10 days a couple of weeks later due to anxiety and ptsd. I have never had an outbreak or other symptoms. At the three month mark I got another IGG and a western blot. Both were negative for HSV1 and 2.

Can taking Valtrex for 10 days (2 time periods during the 3 months) effect my blot or IGG? It was 500 mg 2 tablets 2x per day.

How do PCRs create a false negative? It was labquest

Hello?

So weird, I answered this and don’t know where the answer went.
False positive HSV PCR’s are rare but happen. Have you actually seen the result? If not, I would ask for a copy to be certain this is what you think it is.

If the western blot is negative for HSV 2, I think you should rely upon it as your situation did not present a risk for HSV 2.
I think the amount of Valtrex that you’ve taken should not interfere with the western blot
Do you mean what creates a false positive PCR?

1. Statistically speaking, how often do you see false negative western blot tests as A result of Valtrex use?

2. I asked for a copy of my results and it simply says “positive” and then “within normal range”

I never went near his genitals and the only contact we had was kissing and him using his strap on which was apparently brand new.

For context. I am a female and the last time I had sex was 2 years ago (only 3 partners) before this encounter. I would assume the IGG and western blot would have picked up on an old exposure.

The only contact I had with this person was kissing. He used a strap on to do what he did.
