| Methodology: | Inductively Coupled Plasma/Mass Spectrometry (ICP/MS) | ||||||||
| Edit Date: | 3/17/2008 | ||||||||
| Performed: | Tuesday, Thursday, Saturday | ||||||||
| Released: | 1-4 days after setup at PeaceHealth Laboratories’ reference lab. | ||||||||
| CPT Code: | 82495-90 | ||||||||
| Specimen Collection Details | |||||||||
| Collection: | One 6 mL royal blue top trace element serum (no additives) tube. | ||||||||
| Handling: | Allow to clot, centrifuge and separate serum from cells and immediately pour into either an ARUP Trace Element-Free transport tube, available from Client Services, or a royal blue trace element-no additive tube. Do not allow serum to remain on cells. Refrigerate. | ||||||||
| Stability: | If the specimen is collected and stored in the appropriate container, the trace element values do not change with time. | ||||||||
| Standard Volume: | 2 mL serum. | ||||||||
| Minimum Volume: | 0.5 mL serum. | ||||||||
| Transport: | Refrigerated. | ||||||||
| Rejection Criteria: | Use of any tube other than specified; specimen not clotted or separated from cells; hemolysis. | ||||||||
| Reference Range: | |||||||||||||||||||
| ≤ 5.0 µg/L
Elevated results from noncertified trace element-free tubes may be due to contamination. Elevated concentrations of trace elements in serum should be confirmed with a second specimen collected in a trace element-free tube, such as royal blue sterile tube (no additive). |
