Specimen:
Collect
- One Royal Blue (EDTA)
- Random Urine in Sterile Specimen Container
Submit
- One 6 mL (Min:0.5 mL) Whole blood in Royal Blue (EDTA). Submit Refrigerated.
- One 3 mL Random Urine in Sterile Specimen Container. Submit Frozen. Submit in a Standard Transport Tube.
- Two 7 mL (Min:0.5 mL) Random Urine in Trace Element Free Tube. Submit Refrigerated.
- One 2 mL (Min:0.5 mL) Random Urine in Sterile Specimen Container. Submit Refrigerated. Submit in a Standard Transport Tube.
Special Handling
- Patient Prep: To avoid contamination, please collect specimens at the beginning of work shift. Blood and urine should be collected the same day.
Submit 4 aliquots for urine, labeled with test:
B2 Micro: Transfer 3 mL aliquot from original urine collection to an ARUP Standard Transport Tube. Adjust the pH of this specimen immediately after pouring off collection, so the pH is between 6 and 8. Use 1M HCl or 5 percent NaOH to adjust the urine pH. Label tube as 2 Microglobulin. Freeze within one hour of collection.
Stability: Ambient: 8 hours. Refrigerated: 2 days. Frozen: 2 months.
Cadmium: Transfer a total of 7 mL aliquot from original urine collection to two Trace Element-Free Transport Tubes. Label tube as Cadmium.
Stability: Ambient: 1 week. Refrigerated: 2 weeks. Frozen: 1 year.
Creatinine: No adjustment.
Stability: Ambient: 2 days. Refrigerated: 1 month. Frozen: 6 months.
