Test Code
MPZ DNA(O)
CPT Codes
81405
Preferred Specimen
8 mL whole blood collected in EDTA (lavender-top) tubes
Pediatric (0-3 Years): 2 mL whole blood
Pediatric (0-3 Years): 2 mL whole blood
Minimum Volume
6 mL • Pediatric: 1 mL
Instructions
Please label each specimen tube with two forms of patient identification. These forms of identification must also appear on the requisition form.
Shipping conditions: Avoid freezing. Must arrive Monday through Friday.
Note: Higher blood volumes ensure adequate DNA quantity, which varies with WBC, specimen condition, and need for confirmatory testing. Patients, 0-3 years have higher WBC, yielding more DNA per mL of blood.
