I now have 78 people with positive supplemental tests from LabCorp and negative western blots. I don’t trust this test in their hands at this point. EverlyWell also has many false positives, so I’m glad your result was negative.
If you can’t feel comfortable with those results, your Quest test is also positive, and you are worried, do the western blot.
You are correct that there can be some cross-reactivity with HSV 1 on the IgG tests.
