Normal values may vary from one laboratory to another, reports MedlinePlus. An increase of uric acid in the blood may be attributed to a number of factors, including alcoholism, acidosis, chemotherapy-related side effects, gout and diabetes. Other causes include leukemia, renal failure, excessive exercise and a purine-rich diet. Additionally, high uric acid levels may occur as a result of decreased excretion through the kidney. Certain drugs, including theophylline, caffeine, phenothiazides and aspirin, may also cause an increase. When uric acid levels are higher than normal, solid crystals may form in body joints, resulting in gout.
Lower values of uric acid may be due to liver disease, Wilson’s disease and some kinds of cancer, according to WebMD. Low-protein diets and large amounts of aspirin (more than 1,500 milligram per day) may also lower uric acid levels.
Patients are advised to avoid eating or drinking anything for four hours prior to a uric acid blood level test, notes MedlinePlus. Additionally, patients may be asked to discontinue certain medications before having the test.Learn more about Medical Ranges & Levels
