The is no chemical in urine that will ignite it is not normally flammable unless something flammable is added to it. I saw on TV that a drunk guy killed himself by drinking gas and urinating on a camp fire that went up in a blaze. ChaCha on. Urine is not flammable. There is too much water in urine for it to catch fire.
After urinating a small amount into the toilet bowl to clear the urethra of contaminants, collect a sample of urine in a clean or sterile container. About 1 - 2 ounces of urine is needed for a test. Remove the container from the urine stream without stopping the flow. You may finish voiding into the toilet bowl.
