Informed Consent Required:This test requires physician attestation that patient consent has been received

Technical Information


Clinical Significance:This diagnostic panel detects DNA sequence variants and copy number variations (CNV) in genes that are associated with clinical disorders that can present with seizures.
Methodology: Next Generation Sequencing, Copy Number Variation Analyses using Next Generation Sequencing, Targeted Microarray
Reference Range:See Laboratory Report

CPT:81419

Specimen Requirements


Please label each specimen tube with two forms of patient identification. These forms of identification must also appear on the requisition form.

Specimen Type:Whole blood
Specimen Stability: Room temperature: 10 days, Refrigerated: 10 days, Frozen: Unacceptable,
Specimen Requirements: 8 mL (6 mL minimum) whole blood collected in two (lavender-top) EDTA tubes. Pediatric (0-3 years): 2 mL (1 mL minimum)
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.

Shipping Considerations


Transport Temperature:Room temperature
Set-up/Analytic Time:28-35 days
