TSC2 DNA Deletion Test
Test Code92319
CPT Codes
81406<br /> Limited Access 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.
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. 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.
Specimen Note: 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.
