Valtrex and IGG test

[Sassy2543]

I have been on daily meds since I was visually diagnosed 2 years ago. How long should I be off of them before I test in order to not get a false negative?

You might want to ask a lab/doctor/pharmacist that question. Usually long term usage means it won't clear as fast as someone that just the only takes it occasionally. I would think it also depends on the patient and their creatinine clearance. (They should be able to get you an estimate though)
