While the IGG test looks for a single antibody protein that is different between HSV 1 and hSV 2, the western blot looks for all 16 antibody proteins and four must be present to be called positive.
An inconclusive inhibition assay is likely negative.
I’m sorry that your provider is so uninformed about herpes antibody testing, including advising in favor of IgM test which is not recommend by the CDC and saying the blot is like other antibody tests when it is very different.
