The dilution phenomena is only temporary - once youve urinated out the fluids that were consumed, the bladder is replenished with fresh THCA-laden urine and thus the donor would resume testing positive for THC.

Thats why it is stressed that anytime you test yourself, you always use the first urination of the day when THCA levels are at their highest. By using the first urination, you are testing yourself under the worst-case scenario. And if you are routinely testing negative under that "worst-case scenario", then its a safe bet that there will be no detectable amount of THCA left in the body to fluctuate.
Thanks for the reply. This is all true, and as such, I would assume my official test would be more diluted than anything since I had to drink a few glasses of water when I got there. If I cleared out my fluids with the urine at the test site, then wouldn't it make sense that the test I took a few hours later would have been dirtier, so to speak, since I had not pissed in two hours?

Thanks again for the clarification. Much appreciated
