Uric Acid
About Test
The Uric Acid assay measures the concentration of uric acid, a waste product formed from the breakdown of purines in the body, primarily in the blood. This test is essential for assessing kidney function and diagnosing conditions such as gout and kidney stones. Uric acid levels can be influenced by various factors, including diet, genetics, and certain medical conditions. Elevated uric acid levels, known as hyperuricemia, may indicate conditions such as gout, kidney disease, or excessive purine intake. Hyperuricemia can lead to the formation of urate crystals in joints, causing pain, swelling, and inflammation characteristic of gout attacks. Conversely, low uric acid levels are less common but could be associated with conditions such as Wilson's disease, chronic lead poisoning, or certain medications' side effects. Doctors often include uric acid testing as part of routine health check-ups, especially in individuals with a history of gout or kidney stones. This test helps diagnose and monitor various medical conditions and guides treatment decisions to maintain optimal uric acid levels in the body.
