Urine uric acid may supplement serum uric acid testing when trying to identify conditions in which there is alteration of uric acid production or excretion e. g. , gout, leukemia, renal disease.
Uric acid is a normal waste product of protein breakdown in the body. Low levels within a health screening are generally of no concern, but high levels can lead to gout - an acutely painful inflammation of the joints. High uric acid can also be associated with some medication (especially diuretics), diet or possibly be of genetic origin
