Specimen Collection Requirements
Urine, in a 24 hour collection container. Specimen should be refrigerated during collection.
Aliquot from a well-mixed 24-hour urine collection and refrigerate. Adequate refrigeration is the most important aspect of specimen preservation. Preservation can be enhanced by adjusting the pH to 2-4 with 6M hydrochloric acid. Record total volume and collection time interval on the aliquot and test request form.
