Please Note: 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.
Special Instructions: A separate EDTA whole blood tube is needed for molecular tests. Collect additional samples for other testing that requires EDTA whole blood. Multiple cardiovascular-related genetic tests can be performed on a single specimen. A second lavender-top (EDTA) tube is required if non-genetic tests are simultaneously ordered that require a lavender top (EDTA) tube. For whole blood samples, follow normal phlebotomy procedures.
Transport: Store EDTA whole blood at 2°C to 8°C after collection and ship the same day per packaging instructions provided with the Cleveland HeartLab, Inc. shipping box.
Ambient (15-25°C): 8 days
Refrigerated (2-8°C): 8 days
Frozen (-20°C): 30 days
Deep Frozen (-70°C): 30 days
Causes for Rejection: Specimens other than EDTA whole blood; improper labeling; samples not handled and stored properly; samples older than stability limits.
Methodology: Real-Time Polymerase Chain Reaction (RT-PCR)
Turn Around Time: 4 to 7 days
Reference Range: See Laboratory Report
Clinical Significance: This test determines the subtypes of ApoE which will aid in the risk assessment of coronary heart disease (CHD) and hyperlipoproteinemia.
