HSV blood test results

Sexual health
1

Hi guys. I got STI screening done and took also HSV blood test with it. No symptoms of any kind and everything came back negative.

Results are
HSV1 IgG <0.09
HSV2 IgG <0.50
HSV IgM <0.500
Limit for positive result is >0.9

And statement from the lab: No sign of HSV antibodies.

I had a new sexual contact (protected sex and protected oral, not really risky fluid contacts or anything) two weeks prior to taking that test and was wondering that HSV2 and IgM results 0.5 vs HSV1 0.09 result. Is it just lab measurement accuracies when there is nothing or are those numbers actually on the rise? I am planning to take another screening in couple months anyway just to double check.

What do you think, any past experiences with blood tests?

Update on this HSV test at 6 week mark. New results:
HSV1 IgG 0.12
HSV2 IgG <0.5
HSV IgM <0.5

All under the limit 0.9 and HSV2 result is the same as before. I think I believe the results are truly negative.
