unfortunately you had all the wrong teting done for herpes. you have to repeat it all with the proper testing which would be type specific herpes igg blood testing.
your 22,7 igg was a combined igg which was totally useless and in fact inappropriate for someone in their 40's. 60% of adults that age have hsv1 so it automatically comes back + and tells you nothing. the type specific testing will break it down into hsv1 igg and hsv2 igg and give you separate results for each which is useful information.
the igm herpes test is not appropriate either. it is a greatly flawed test that should never be ordered on adults.
I can not comment on your hepatitis C testing. that is not my area.
