| Special Handling |
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.
Measure and record volume on the requisition and container prior to aliquotting.
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 are ordered, please submit a separate urine specimen (containing no additive) for the metal testing. |
