Quickfix plus used fro drug screening

Hi everyone. I’m freaking out 🫠. I used quickfix for a drug screening. Temp was at 96 when I dumped it in the cup. I took 1 min in the toilet, they weren’t suspicious at all, also because the nurse had enough pee for a split but she just took a single specimen collection. The sample was sent to Labcorp. I’m freaking out seriously cause I need this job seriously. I don’t do drugs, but I used to smoke weed and my pee wasn’t clean for a drug test. I checked my batch and the expiration date was september 2027. I did everything correctly but I read about people not passing the test anyway. More than a question this post is because I’m so nervous idk what to do if I failed it. If they call me and tell me they found a different ph level or nitrite (like it happened for other people) can I just say I had a UTI? I saw that this can cause nitrite or different ph levels. I shaked really well the bottle 30 min before the test but I couldn’t shake well in the toilet cause she was attached to the door.
