Yes, I have of course heard of this. There are several reasons one might not agree to testing.
1) they don’t know what to do with a positive antibody test in someone who has had no symptoms
2) they don’t want to deal with the emotional fallout of telling someone they have a lifelong transmissible infection
3) they don’t want to “needlessly” upset someone
4) they believe that everyone who has herpes would know it because everyone with herpes has symptoms
5) they believe the tests are not type specific
6) they believe “everyone has herpes anyway”
7) they believe there are high rates of false positives (not so: about 2.7% of people who take test has a false positive and that can be sorted out with the western blot”
Those are the main reasons, all of which I disagree with.
