I wonder if I should also drink alot of water and take another test to see how that turns up?
Drinking alot of water would dilute the THCA concentration that is present in your bladder to where the urine sample would register a negative on the home test (or even the assays used at the labs, and providing that the THCA concentration is not too high). This dilution phenomena, however, is only temporary - once the fluids youve ingested had all been urinated out, the bladder is replenished with fresh THCA-laden urine by the kidneys....back to square one.
