Measures androgens and their metabolites in urine. Useful for evaluating adrenal and gonadal function and diagnosing hormone-secreting tumors or adrenal hyperplasia.
24 hour urine
8 mL
Transport tube
No special preparation is required for this test. You may eat, drink, and take your medications as normal, unless instructed otherwise by your healthcare provider.
Transfer two 4 mL Aliquots from a well-mixed 24-hour urine collection. Record total volume and collection time interval on transport tube and test request form. Adequate refrigeration is the most important aspect of specimen preservation. Preservation can be enhanced by adjusting the pH to 2-4. Adjust the pH by adding an acid, such as 6 mol/L HCI. A pH of less than two will decrease analyte stability.
