Preferred Specimen
8 mL whole blood collected in each of two EDTA (lavender-top) tubes, or
Pediatric 0-3 years: 2 mL whole blood
Pediatric 0-3 years: 2 mL whole blood
Minimum Volume
6 mL • 1 mL pediatric whole blood
Instructions
Please label each specimen tube with two forms of patient identification. These forms of identification must also appear on the requisition form.
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.
