Meperidine and Metabolite Quantitative, Urine
Also known as: MEPERI U
Use
This test is used for the quantitative detection of meperidine and its metabolite, normeperidine, in urine. Meperidine is a synthetic narcotic analgesic, often found in drug testing for overdose and potential abuse situations. Normeperidine, the primary metabolite, is noted for being potentially toxic, particularly with chronic use, and can cause convulsions and other severe effects if it accumulates.
Special Instructions
Preferred test for following up on presumptive screening results. Transport 2 mL urine in an ARUP standard transport tube. Separate specimens are necessary when multiple tests are ordered as this test is not performed at ARUP.
Limitations
Test developed by NMS Labs and not FDA approved. Normeperidine may accumulate during chronic therapy, causing more pronounced toxic effects than meperidine itself, including the risk of convulsions and prolonged half-life.
