Wow, I can see why you are confused.
First, the IgM is a poor test and the CDC says never to use to try to diagnose herpes.
Next, it looks like a combined HSV 1 and 2 test was ordered which also should never be used as there are false positives here as well and if you have HSV 1 already, it can make the HSV 2 part of the test look positive.
Next, you had the proper test done although this type of test does not give an index value, which is very useful in understanding what is going on. But that’s OK. It picked up your HSV 1 infection
And then next, for reasons that are completely unknown, a blood PCR test was done which is of course negative because herpes is not in your blood, it is in nerves and skin.
Whoever did all of this ordering is confused about how to detect herpes through blood testing.
