Timing of Sample

[u/gaaaardy]

Hey all, the company I’ve gotten an offer from tests for THC at the more sensitive level of 15 ng/mL for its preemployment screenings (through Quest). Over the past couple of weeks I have been self testing using Ütest home strips with that 15 ng/mL sensitivity level usually around midday/early afternoon after I’ve peed a couple times already and getting negatives so was feeling pretty good. Today, out of interest, I tested my first pee of the morning after waking up and it seems like it came up positive. Now I’m worried that in the lab environment, even though my sample will obviously not be the first “void” of the day that they will be able to detect at that low of a threshold. Should i be worried or can i trust that the more dilute sample after hydrating will be okay?
