| 84431:HEAVY METALS PANEL, URINE, WITH REFLEX TO ARSENIC FRACTIONATED | |||||||||
| Alias Names: | Metals / Urine / Quantitative | ||||||||
| Methodology: | Inductively Coupled Plasma/Mass Spectrometry (ICP/MS) | ||||||||
| Edit Date: | 6/11/2010 | ||||||||
| Components: | Arsenic (As) / Mercury (Hg) / Lead (Pb) / Creatinine | ||||||||
| Performed: | Monday-Saturday | ||||||||
| Released: | 1-4 days after setup at PeaceHealth Laboratories’ reference lab. | ||||||||
| CPT Code: | 82175-90 / 83655-90 / 83825-90 / 82175 if reflexed | ||||||||
| Specimen Collection Details | |||||||||
| Collection: | 24-hour or random urine in a clean dry plastic container. Refrigerate during collection, storage, and transport. | ||||||||
| Handling: | Mix well and aliquot. Record total volume and collection time interval on container and on requisition. Studies indicate that, if tested within 8 days of collection, refrigeration alone of urine during and after collection preserves the specimen as well as preservatives. |
||||||||
| Stability: | 7 days ambient, 14 days refrigerated. or 1 year frozen. | ||||||||
| Standard Volume: | 10 mL aliquot from well mixed collection. | ||||||||
| Minimum Volume: | 5 mL aliquot. | ||||||||
| Transport: | Refrigerated. | ||||||||
| Comments: | If the Arsenic, Urine is above 35.0 µg/L the test automatically reflexes to an Arsenic Fractionated, Urine. A speciation is performed to differentiate between organic, inorganic, and methylated arsenic. | ||||||||
| Rejection Criteria: | Urine collected within 48 hours after administration of a gadolinium (Gd) containing contrast media (may occur with MRI studies); acid-preserved urine. | ||||||||
