Your doctor will likely order this specific test if: You Have Kidney Stones: It identifies if high uric acid in your urine (Hyperuricosuria) is causing stones to form. You Have Recurrent Gout: It helps classify you as an "over-producer" or "under-excretor" of uric acid, which helps doctors prescribe the correct medication (e.g., Allopurinol vs. Probenecid). Treatment Monitoring: To ensure your current medications are successfully lowering the amount of uric acid in your system.

Discard the very first urine sample. Empty your bladder completely at the chosen start time (e.g., $7 \text{ AM}$) and flush it. This urine marks the start time. Collect every single drop of urine passed for the next 24 hours and pour it into the large, special container provided by the lab. Empty your bladder exactly 24 hours after the start time, and add this final sample to the container. The collection period is now complete.The container must be kept refrigerated (or on ice) during the entire 24-hour collection period and until it is returned to the lab
