Shingles and Hsv 2 test

I may have had minor case shingles about 20 years ago.
If I did, could this result in a herpes test to be positive ?  Even if no herpes? Or do the tests
Distinguish clearly between the two viruses?
I have not been tested yet but may at 12 weeks for some peace if mind
Thank you

Dear 48m,

If you had herpes infection in past, then Herpes simplex virus (HSV) 1 or 2 antibody (IgG) test can come positive. This test is indicative of a past infection. It does not however mean that you have any recent infection.

HSV IgM test is indicative of active or a recent infection.

HSV 1 & 2 infection can over lap or cross-over at times. It is also common to have false positive result in cases the value is just over 1. Anything over 2 is frank positive and indicates infection.

This is where your history of infection becomes important.

So to answer your query, "if you had shingles in the past you may get a positive antibody (IgG). IgM antibodies which suggests recent infection would be negative. We could distinguish amongst HSV 1 and 2 if the values are above 2".

I hope this answers your query. Should you have any additional concerns regarding this issue, I would be happy to address them within the next two days.
