Preferred Specimen
8 mL whole blood collected in each of two EDTA (lavender-top) tubes, or
Pediatric 0-3 years: 2 mL whole blood


Minimum Volume
6 mL • 1 mL pediatric whole blood


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.


Transport Temperature
Room temperature

Room temperature: 10 days
Refrigerated: 10 days
Frozen: Unacceptable



Methodology
Next Generation Sequencing, CNV Analys using NGS, Targeted Microarray

Setup Schedule
Set up: As needed; Report available: 28-35 days


Reference Range
See Laboratory Report


Clinical Significance
This diagnostic panel detects DNA sequence variants and copy number variations (CNV) in genes associated with genetic forms of epilepsy including generalized, absence, partial (focal), febrile, and myoclonic seizures.
