What medications could cause false negative test

[Lkc1970]

I have read previous posts, but am wondering what medications would cause a false negative 4th gen test.  Medication that I am concerned about is lidocaine viscous.  My Doctor has told me several times that it would not and that I am conclusive non-reactive.  But just checking.

Thanks

Also, the lidocaine was with nystatin as a swish and swallow to treat oral thrush after several courses of antibiotics.  Not sure if that matters or not.

Thank you very much...so my test would be definitely conclusive then?

Hi there,

Medications, including viscous lidocaine, won't affect the outcome of your tests.
