A uric acid blood test, also known as a serum uric acid measurement, determines how much uric acid is present in your blood. The test can help determine how well your body produces and removes uric acid.
Uric acid is a chemical produced when your body breaks down foods that contain organic compounds called purines. These foods include liver, anchovies, mackerel, dried beans, beer, and wine. Purines are also created through the natural process of cell breakdown in the body.
Most uric acid is dissolved in the blood, filtered through the kidneys, and expelled in the urine. Sometimes, the body produces too much uric acid or does not filter out enough of it. Hyperuricemiais the disorder that occurs when you have too much uric acid in your body. One cause of hyperuricemia is increased cell death, due to cancer or cancer treatments, can lead to an accumulation of uric acid in the body.
It is also possible to have too little uric acid in your blood, which is a symptom of liver or kidney disease, or Fanconi syndrome, a disorder of the kidney tubules that prevents the absorption of substances such as glucose and uric acid, which are then passed in the urine.
High levels of uric acid in your blood may suggest:
• Diabetes
• Gout (recurring attacks of acute arthritis)
• Chemotherapy
• Bone marrow disorders (such as leukemia)
• A diet high in purines
• Hypoparathyroidism (decreased parathyroid gland function)
• Kidney disorders (such as acute kidney failure)
• Kidney stones
• Multiple myeloma (cancer of the plasma cells in your bone marrow)
• Metastasized cancer (cancer that has spread from its original site)
Low levels of uric acid in the blood may suggest:
• Wilson’s disease (an inherited disorder in which your tissues contain too much copper)
• Fanconi syndrome (a kidney tube disorder)
• Alcoholism
• Liver or kidney disease
• A diet low in purines
