PTEN DNA Sequencing Test
Test Code92865
CPT Codes
81321<br /> Limited Access Code
Preferred Specimen
8 mL whole blood collected in two EDTA (lavender-top) tubes
Pediatric (0-3 years): 2 mL
Pediatric (0-3 years): 2 mL
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.
Note: Higher blood volumes ensure adequate DNA quantity, which varies with WBC, specimen condition, and need for confirmatory testing. Patients, 0-3 years may have higher WBC, yielding more DNA per mL of blood.
