A high uric acid level means a person's body is producing too much uric acid or the kidneys aren't excreting enough from the blood stream. The normal range is between 3.5 and 7.2 milligrams of uric acid per deciliter of blood, reports Healthline, and anything above 7.2 is high.
Too much uric acid in the blood can cause solid crystals to form in joints, reports WebMD. When a high reading is present, possible health conditions include gout, diabetes, chemotherapy, kidney stones, kidney disorders or hypoparathyroidism, reports Healthline. When tests show high levels of uric acid, a doctor may prescribe medications to reduce levels and then retest.
