This is a serious question, please dont ignore this thinking it s a joke or anything please. I ve peed in a number of bottle in order to analyze my urine , and ive noticed that there is always particulate matter floating around. Nothing too big, but lots of chunks none the less. I also notice that a thick white sediment appears at the bottom when it s left to sit for a short time. My urine is normally not very clear, although it can be when I drink a lot of fluids. Thanks for your time, I hope to hear a response.
