Dr. Bill
I hurt my low back while shoveling snow on Friday.
I took 1200mg of regular Ibuprofein on Saturday, then, on Sunday, took 400mg at 8am,
And then I took another 400mg alcohol free ibuprofein at 2pm,
I need to to take ETG/Poly test at 7pm today (monday).
I just found an article that Ibuprofein may cause a false positive on ETG test.

Will it show a false positive?
Thank you very much always.
