Uric acid in the blood
Uric acid is a chemical that is created when the body breaks down substances called purines. Purines are normally produced in the body and are also found in some foods and beverages. Foods with a high purine content include liver, anchovies, mackerel, beans (beans) and dried peas and beer.
Most of the uric acid dissolves in the blood and travels to the kidneys. From there it comes out through the urine. If your body produces too much uric acid or does not eliminate it in sufficient quantities, you can get sick. High levels of uric acid in the blood are called hyperuricemia.
This test is done to see how much uric acid you have in your blood. Another test may be used to check the level of uric acid in the urine.
How the test is performed
A blood sample is needed. Most of the time, blood is drawn from a vein located on the inside of the elbow or the back of the hand.
Preparation for the exam
Preparation for the exam has been extended.
You should not eat or drink anything during the 4 hours before the test, unless you have been told something different.
Many medications can interfere with the results of the blood test.
Your health care provider will tell you if you need to stop taking any medication before the test is done.
DO NOT suspend or change your medications without first talking to your provider
Reasons why the test is performed
Reasons why the exam is performed has been extended.
This test is done to see if you have an elevated level of uric acid in your blood. High levels of uric acid can sometimes cause gout or kidney disease.
You may have this test if you have had or are about to have certain types of chemotherapy. Rapid weight loss, which can occur with such treatments, can increase the amount of uric acid in the blood.
Normal results
Normal results has been extended.
Normal values are between 3.5 and 7.2 milligrams per deciliter (mg / dL) ..
The ranges of normal values may vary slightly between different laboratories. Talk to your provider about the meaning of the specific results of your test.
The above examples show the range of common measurements for the results of these tests. Some laboratories use different measurements or can evaluate different samples.
Meaning of abnormal results
Meaning of the abnormal results has been extended.
Uric acid levels above normal (hyperuricemia) may be due to:
Side effects related to chemotherapy
Excessive exercise
Drop
Leukemia
Medullary cystic kidney disease
Purine rich diet
Uric acid levels below normal may be due to:
Fanconi syndrome
Low purine diet
Syndrome of inappropriate secretion of antidiuretic hormone (SIADH)

Chronic gouty arthritis
Chronic kidney disease
