Test Code901335
CPT Codes
81406<br /> Restricted Client Code
Physician Attestation of Informed Consent
This germline genetic test requires physician attestation that patient consent has been received if ordering medical facility is located in AK, DE, FL, GA, IA, MA, MN, NV, NJ, NY, OR, SD or VT or test is performed in MA.
Includes
Related to all allelic disorders
Preferred Specimen
8 mL whole blood collected in 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
Instructions
Please label each specimen with two forms of patient identification. These forms of identification must also appear on the requisition form.
Avoid freezing.
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.
