| SPECIMEN REQUIREMENTS | ||||
|---|---|---|---|---|
| Specimen | Specimen Volume (min) | Specimen Type | Specimen Container | Transport Environment |
| Preferred | 5 mL (2.5 mL) | Urine, 24-hour | 24 Hour Urine Acid Washed Container | Room Temperature |
| Alternate 1 | 5 mL (2.5 mL) | Urine, Random | Acid Washed, Trace Element Free Contatiner | Room Temperature |
| Instructions | Notes: 2.5 mL (Note: This volume Does NOT allow for repeat testing.) Specimen Type: Plastic urine container, no preservative Specimen Storage: Maintain specimen at room temperature. Specimen Collection: Sampling time is not critical for industrial exposure monitoring. Metals with timing "not critical" have very long elimination half-lives and accumulate in the body over years, some for a lifetime. After a couple of weeks of exposure, specimens can be collected at any time. Optional protocol: If the specimen is a 24-hour collection, instruct the patient to void at 8 AM and discard the specimen. Then collect all urine including the final specimen voided at the end of the 24-hour collection period (ie, 8 AM the next morning). Screw the lid on securely. Collect without preservatives. Mix well. Sampling time is not critical for industrial monitoring. Special Instructions: Request form MUST state total volume collected in 24-hour, if applicable. No preservatives. Preservatives used for routine analysis may contain mercuric oxide (ie, Stabilur), which interferes with all metal testing. If both urinalysis and metal testing ar Specimen Stability: Ambient: 14 days, Refrigerated : 14 days, Frozen: 14 days |
