Thanks for the prompt reply.

The reason I listed 25ng/ml in my post was based on the fact that the home test cut offs are 50ng/ml. And if the maximum possible half-life for thc metabolite elimination is 10 days, then in my mind it would follow that you would be at 25ng/ml or less 10days after the first home test you pass.

So while I may not have been clear in my original post I don't suspect that I would be taking a 20ng/ml test but that is why my other question in the original post was about the LabCorp CoC form that didn't have the test specified or a number of any sort other than just '5 panel'.
