I went in to get my test done today. It went a lot better than I expected. They made no fuss whatsoever about there being no urine in the toilet, and that there was no odor, and not a lot of foam. I am pleased with the experience.

I was a little worried that I wouldn't have enough of the fake urine to fill it up to the line since the required amount is 2oz, and all I had was 2 oz...The bottle leaked a little bit, which worried me even more. But I had plenty of fake urine to get above the line

I passed the temperature check. They sealed it and said the results will be in within 24-72 hours, and my employer would let me know the results.

The result I get all depends on the ultra pure synthetic urine. So hopefully the batch I had is good, and will pass all the tests they do on it.

At Concentra they prevent you from flushing, and they have a blue liquid in the toilet bowl. I feel like it is dangerous to use my dirty (real) urine to fill the Rating: 5
