Herpes screening is discouraged in the US unless symptoms are present as the widely available IgG tests have terrible specificity. While the false negative rate is practically 0, they have a false positive rate of around 20%. The only high-accuracy confirmatory test (at least in the US) is the Western Blot but there's only a handful of labs in the country that offer it.

The current tests would result in a substantial fraction of the population running around thinking they have a highly stigmatized STI that they in fact do not have with little to zero ways of getting a more accurate test.
