Preferred Specimen
LABCORP LAB: URINE CUP (Room Temperature) Min Vol: 10


Instructions
7 mL collected in Lavender-top (EDTA) tube or green-top (heparin) tube; submit original full, unopened tube. (Minimum 0.6 mL) Sampling time is end of shift for industrial exposure monitoring. Analytes with timing “end of shift” (meaning the last two hours of exposure) are eliminated rapidly with a half-life less than five hours. Such compounds do not accumulate in the body and, therefore, their timing is critical only in relation to the exposure period.


Transport Temperature
Refrigerate immediately after collection. Do not remove cap.
