What is this test?
This urine panel measures hypoxanthine, xanthine, and urate. These substances are related to purine metabolism, the process that produces uric acid, and can provide information about causes of uric acid buildup or kidney stones.
Why might I need this test?
Your clinician may order this test when there is concern about unusually high uric acid, recurrent kidney stones, or an inherited disorder of purine metabolism. It may also be used to follow the effects of medicines that alter uric acid production.
How is the test performed?
Urine is collected and sent to a laboratory, where the amounts of hypoxanthine, xanthine, and urate are measured. Your clinician may request a single urine sample or a timed collection, such as a 24-hour collection, depending on the purpose of the test.
How do I prepare for the test?
Follow your clinician or laboratory collection instructions exactly. For a timed collection, record the start and finish times and collect all urine during that period; the laboratory may also provide storage and delivery instructions.
Reference range
NCBI: Uric Acid Male 3.5-7.2 mg/dL; Female 2.5-6.8 mg/dLN/A
No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Elevated urinary urate can occur with increased uric acid production, reduced kidney excretion, dehydration, or certain medicines. Changes in hypoxanthine and xanthine may indicate an inherited problem in purine breakdown, such as reduced xanthine oxidase activity. Results should be interpreted with symptoms, medical history, medications, and other kidney or stone tests.
Short name
Urinary purine panel
