Uric acid that comes in blood from the metabolic breakdown of cells and food is filtered by the kidneys and gets excreted. A little amount of uric acid passes out in the stool as well. Uric acid levels in blood increase if an excess amount of it is produced or when the kidneys do not function normally. If the uric acid levels elevate, solid crystals are formed in the joints and kidney stones are also formed. The formation of solid uric acid crystals in the joint may lead to Gout.
The uric Acid test is used to measure the uric acid levels in a blood sample.
