Substituted today, but may have contaminated my urine

[hybrisate]

I had a UA today for pre-employment. I used someone else's clean urine. I was most worried about temperature, but it ended up being fine. However, every time I used the thermometer before I left for the test I wiped it dry on a paper towel. Just before I put the bottle in my underwear I noticed it had a bunch of tiny fragments of paper towel in it. I decided to strain it during my test. I put some toilet paper over the container and poured the urine in it, but the toilet paper got soggy immediately. Most of the sample went through it though, however I was so nervous I poured the rest of it in without straining it. So I believe there are tiny fragments of paper towel and possibly toilet paper in my sample. Is this going to be a problem? Can it cause me to fail if there is? Thanks for any help, I'm stressed.

This thought just came to me earlier, could those paper towel and/or toilet paper fragments raise the specific gravity above the acceptable level? I don't know anything about specific gravity, but for some reason I'm really worried this is a possibility. Anyone??
