Harnsäure

Uric acid (UA) is a waste product formed from the breakdown of purines, which are found in certain foods and drinks. It is primarily excreted by the kidneys and measured in the blood to assess its concentration. The biological measurement of uric acid provides insight into renal function and purine metabolism. Clinically, uric acid levels are significant as they can indicate conditions such as gout, a form of inflammatory arthritis caused by uric acid crystal deposition in joints, and hyperuricemia, which is an elevated level of uric acid in the blood. Researchers have also found associations between high uric acid levels and hypertension, as well as potential links to subclinical hypothyroidism. In the context of longevity, lower uric acid levels have been observed in centenarians, suggesting a possible role in promoting a longer lifespan. For athletes and biohackers, maintaining optimal uric acid levels is important as it may influence inflammation and recovery. However, uric acid levels can be affected by various factors such as diet, medications, and renal function. Fasting is not typically required for testing, but certain drugs and conditions can interfere with accurate measurement.
