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.
Preferred Specimen
8 mL whole blood collected in two EDTA (lavender-top) tubes
Minimum Volume
6 mL
Instructions
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.
