Labcorp catalog pageMethod and collection
- Method
- Ion-exchange chromatography/spectrophotometry
- Collection
- Instruct the patient to void at 8 AM (or 8 PM) and discard the specimen. Then collect all the urine, including the final specimen voided at the end of the 24-hour collection period (ie, 8 AM [or 8 PM] the following day), in the 24-hour collection container (Labcorp No. 23301). Specimen must be kept refrigerated during collection. Measure and record on the test request form the 24-hour total volume. Mix well. Transfer the urine into a LabCorp amber plastic frozen transport tube with amber cap (Labcorp No. 78656). Label the container with the patient's name, date, and time collection started and finished. The specimen should be frozen immediately and maintained frozen until tested. (If amber tube and cap are not available, cover a clear plastic transport tube completely from top to bottom with aluminum foil. Identify the specimen with the patient's name directly on the transport tube and the outside of the aluminum foil. Secure with tape.) To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested .

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
