METAF | Test | METAF | Metanephrines, Fractionated, 24 Hour, [NAME] | Metanephrines, Fractionated, 24h, U | Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) Stable Isotope Dilution Analysis | [NAME], 24-hour graduated: 24Urine |  |  | 10 | mL | Container/Tube: Plastic, 10-mL urine tube (Supply T068) [NAME]: 10 mL Collection Instructions: 1. Collect urine for 24 hours. 2. Add 10 g (pediatric: 3 g) of boric acid or 25 mL (pediatric: 15 mL) of 50% acetic acid as preservative at start of collection. Additional Information: 1. 24-Hour volume is required. 2. See [NAME] in Special Instructions for multiple collections. 3. Tricyclic antidepressants, labetalol, and sotalol medications may elevate levels of metanephrines producing results which cannot be interpreted. If clinically feasible, it is optimal to discontinue these medications at least 1 week before collection. For advice on assessing the risk of removing patients from these medications and alternatives, you may consider consultation with a specialist in endocrinology or hypertension.
