Hyperuricemia (C0740394)

Definition (NCI) Elevated blood concentrations of uric acid.
Definition (NCI_NCI-GLOSS) A buildup of uric acid (a byproduct of metabolism) in the blood. Hyperuricemia is a side effect of some anticancer drugs.
Definition (NCI_CTCAE) A disorder characterized by laboratory test results that indicate an elevation in the concentration of uric acid.
Definition (MSH) Excessive URIC ACID or urate in blood as defined by its solubility in plasma at 37 degrees C; greater than 0.42mmol per liter (7.0mg/dL) in men or 0.36mmol per liter (6.0mg/dL) in women. This condition is caused by overproduction of uric acid or impaired renal clearance. Hyperuricemia can be acquired, drug-induced or genetically determined (LESCH-NYHAN SYNDROME). It is associated with HYPERTENSION and GOUT.
Definition (CSP) excessive uric acid or urate in blood as defined by its solubility in plasma at 37 degrees Celsius; greater than 0.42mmol per liter (7.0mg/dl) in men or 0.36mmol per liter (6.0mg/dl) in women; this condition is caused by overproduction of uric acid or impaired renal clearance; hyperuricemia can be acquired, drug-induced or genetically determined; it is associated with hypertension and gout.
