I really don't like when they combine the hsv tests. The results are confusing and some what useless. Yes you had a very low positive test result which can mean anything or absolutely nothing. I bet you don't have either hsv strain.
The best advice I can give you is have another blood test done. No igm testing. Just get a type specific igg test for hsv1 and hsv2. Meaning they test each one separately, so you will have a result value for each
