PQNU | Test | PQNU | Porphyrins, Quantitative, [NAME] | Porphyrins, QN, U | High-Performance Liquid Chromatography (HPLC) with Fluorometric Detection Includes quantitation of coproporphyrins, uroporphyrins, and intermediate porphyrins (heptacarboxyl, [NAME], and pentacarboxyl). Includes liquid chromatography-tandem mass spectrometry (LC-MS/MS) determination of porphobilinogen. | Plastic, urine bottle: [NAME] |  |  | 50 | mL | Container/Tube: Amber, 60-mL urine bottle (Supply T596) [NAME]: 20-50 mL Collection Instructions:  1. Patient should abstain from alcohol for 24 hours prior to, as well as during, collection. 2. Collect a 24-hour urine specimen. 3. Add 5 g of sodium carbonate (Supply T272) as preservative at start of collection. This preservative is intended to achieve a pH of >7. Do not substitute sodium bicarbonate for sodium carbonate. 4. The container should be refrigerated and protected from light as much as possible during collection. 5. Protect specimen from light. Additional Information: 1. 24-Hour volume is required. 2. Collection date and time should be documented upon completion of the 24-hour collection. 3. Include a list of medications the patient is currently taking. 4. The pH will generally fall between 7 and 10 if the proper preservative (5 g sodium carbonate) was added to the container before the collection was started. 5. See [NAME] in Special Instructions for multiple collections. Forms: If not ordering electronically, submit a Biochemical Genetics Request Form (Supply T439) with the specimen.
