OK, so if I passed a 50ng/mL home test, then I know I am below 50. So if my half-life is at worst 10 days, then that means after ten days I'd be below 25ng/mL, and after 20, below 12.5 ng/mL? The test I had to take only cost my employer $20 at the lab, any chance the test had an initial cut-off below 50ng/mL at that price?
