PKD2 Deletion Test
Test Code93763
CPT Codes
81479<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.
DNA yields and quality are better in fresh specimens. However, when necessary, most genetic tests are successful from DNA purified from whole blood that is several days old.
Specimen 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.
