Uric acid is a body waste that results from the degradation of purines. Purines are the building blocks of DNA, which is found in the body's cells. Under normal circumstances, uric acid is eliminated by the kidneys, which are responsible for keeping levels within the normal range. High blood uric acid levels can be caused by several conditions. For example, the body can make too much of it or the kidneys may have trouble eliminating it as usual.
If the result is too high
Results will be higher in people with gout. Blood uric acid levels may be higher in people with leukemia or kidney disease, as well as in pregnant women suffering from eclampsia.
If the result is too low
Certain kidney anomalies or enzymatic dysfunctions can result in low blood uric acid levels.
Certain foods contain large amounts of purines (anchovies, brain, heart, liver, kidneys, shrimp, venison, herring, mackerel, scallop, veal sweetbread, sardine, gravies, soup base, etc.) The body transforms purines found in these foods into uric acid. As a result, uric acid levels are increased.
In addition, certain drugs, such as diuretics (drugs that increase urine production and output), can affect the result of this test. These drugs reduce uric acid elimination. The following are examples of diuretics:
What you need to know before the test
Before going for blood tests, a procedure or other exam, it is best to always bring a list of all the drugs you take (prescription, OTC and natural health products). Unless told otherwise, you should take your medication as usual on the day of the test. When in doubt, ask your pharmacist for more information.
