what does uric acid do

Most of the uric acid is filtered out by the kidneys and passes out of the body in urine.A small amount passes out of the body in stool.But if too much uric acid is being produced or if the kidneys are not able to remove it from the blood normally, the level of uric acid in the blood increases.hy It Is Done.
