Normal uric acid levels in the blood range between 3.5 and 7.2 mg/dL, according to MedlinePlus. Higher than normal levels of uric acid can cause gout or kidney disease.
Uric acid is a chemical created when the body breaks down purines, substances found in some foods and drinks including liver, anchovies, mackerel, dried peas and beans and beer, MedlinePlus explains. Most uric acid dissolves in the blood and is carried to the kidneys then passed in the urine. Certain types of chemotherapy and rapid weight loss can increase the amount of uric acid in the blood, as can other conditions including alcoholism, diabetes, leukemia and toxemia of pregnancy.
