Specimen Collection Details
Collection: 24-hour urine in a clean, dry plastic container. Refrigerate during collection.
Handling: Adequate refrigeration is the most important aspect of preservation. Preservation can be enhanced by adjusting pH to 2.0-4.0 using 6 mol/L HCl. pH less than 2.0 will decrease stability.
Stability: Specimen stable 4 hours ambient, 14 days refrigerated, or 1 month frozen.
Standard Volume: 5 mL aliquot from a well mixed 24-hour urine collection.
Minimum Volume: 3 mL aliquot from a well mixed 24-hour urine collection.
Transport: Refrigerated; or if frozen, on dry ice.
