The home tests are just as accurate as the assays the labs use for the initial screen.

Since your U/A is on the 22nd, take one more home test on the 19th, but this time use the first urination of the day (when THCA concentrations would be at its highest and not affected by any fluids consumed prior, as it would be with afternoon/evening urinations). If you test negative with the first urination of the day (regardless of line intensity), youre good to go. :thumbsup:
