URINE

Urine is a fluid produced by the kidneys. Urine contains the end products of nitrogen metabolism - urea, uric acid and creatinine as well as sodium chloride. Urine is extensively tested in medicine for the diagnosis of disease, and immunological analysis of urine is commonly used to test for pregnancy in humans.

In industry, a dilute solution of urine was long traditionally used as a degreaser for sheep's wool before it was combed, spun and woven.
