CPT® Code 84560

The CPT® Code 84560 refers to a laboratory test that measures uric acid levels in urine or synovial fluid. Uric acid is a byproduct of the natural breakdown of purines, which are substances found in many foods and are also produced by the body. Under normal circumstances, uric acid is filtered by the kidneys and eliminated from the body through urine. However, when the levels of uric acid become elevated, it can indicate various health issues. Conditions such as kidney disease, certain types of cancer and their treatments, hemolytic anemia, heart failure, cirrhosis, and a diet rich in purines can lead to increased uric acid levels. Conversely, decreased levels of uric acid may be associated with gout, folic acid deficiency, and the use of specific medications. The testing process involves obtaining a urine specimen, which can be collected over a 24-hour period or as a random sample. The uric acid concentration is then measured using a technique known as quantitative spectrophotometry. In cases where synovial fluid is tested, it is typically aspirated from affected joints, often those in the feet and legs, where monosodium urate crystals may be present. This fluid is also analyzed using quantitative spectrophotometry to determine uric acid levels. The results of this test can provide valuable insights into a patient's metabolic state and assist healthcare providers in diagnosing and managing various medical conditions related to uric acid metabolism.
