Clinical Significance
Elevations of uric acid occur in renal failure, prerenal azotemia, gout, lead poisoning, excessive cell destruction (e.g., following chemotherapy), hemolytic anemia, and congestive heart failure and after myocardial infarction. Uric acid is also increased in some endocrine disorders, acidosis, toxemia of pregnancy, hereditary gout, and glycogen storage disease type I. A low uric acid concentration may be found following treatment by some drugs (e.g., low-dose aspirin), with low dietary intake of purines, in the presence of renal tubular defects, and in xanthinuria.
