Uric Acid, Serum
What is it?
Uric acid is a substance that is normally found in the body. Uric acid can be measured with a blood test. Blood tests are often done when you have a routine physical (fizz-ih-kull) examination (eks-ah-mih-na-shun).
Why do I need it?
If you have sudden symptoms of arthritis (arth-ri-tis), uric acid levels may be done to see if you have gout. Gout is caused by an accumulation of uric acid crystals in the tissues and cartilage (kar-tih-lij). If uric acid builds up in the kidneys, it can form kidney stones. Foods rich in uric acid include liver and kidney. Your caregiver may want you to avoid these foods if you have gout or uric acid kidney stones. Caregivers will explain the test and why you need it.
How do I get ready for the test?
Your caregiver will tell you when to have your blood test done. Do not eat or drink anything, except water, for at least 12 hours before the test. You may need to stop taking some medicines before the test. Ask your caregiver if you should not take your normal medicines until after your blood is taken.
How is the specimen collected?
A caregiver will put a wide rubber strap around your arm and tighten it. Your skin will be cleaned with alcohol. A small needle attached to a special test tube will be put into a vein in your arm or hand. The tube has suction to pull the blood into it. When the tube is full, the rubber strap, needle and tube are removed. The caregiver will press a piece of cotton where the needle was removed. You may be asked to hold the cotton on the site for a few minutes to help stop the bleeding. Tape may then be put over the cotton on your arm.
What do I do after the test?
You may remove the tape and cotton in about 20 to 30 minutes. Call your caregiver to get the results of your test. Your caregiver will explain what your test results mean for you. Follow the instructions of your caregiver.
You have the right to help plan your care. To help with this plan, you must learn about your lab tests. You can then discuss the results with your caregivers. Work with them to decide what care may be used to treat you. You always have the right to refuse treatment.
