A uric acid test measures the amount of uric acid in your blood. Uric acid is a waste product made when the body breaks down chemicals called purines, which are found in many foods. Most uric acid is filtered by the kidneys and passed out in urine.
Why is it connected to gout?
When the uric acid level in the blood gets too high, crystals can form and collect in a joint. This can cause a sudden, very painful attack of swelling and redness, most often in the big toe. This is gout. A uric acid test is commonly ordered when a doctor suspects gout or wants to monitor someone who already has it.
How to prepare
The sample is a blood draw. Fasting is not usually needed for uric acid, though some laboratories ask for a short fast or a specific time of day, so confirm with the laboratory what applies to you. Some foods and medicines can affect the level, so tell the laboratory what your doctor has asked before you visit.
What a high result can mean
A high uric acid level does not always cause gout, and a normal level does not completely rule it out, so the result is interpreted along with your symptoms. When a result is high, it may be linked to gout, kidney problems, or medicines that raise uric acid. Your doctor will explain what the number means for you and what to do next.
When is it ordered?
Doctors order a uric acid test to help diagnose gout, to check the kidneys, or to monitor people on certain treatments. It is sometimes part of an arthritis or joint pain screen along with ESR and C-reactive protein.
