Specimen Requirements:

Peripheral Blood: Collected aseptically in sodium heparin tubes (usually green top tubes) and immediately rotated thoroughly to prevent clotting. For infants obtain approximately 2 cc and for children and adults obtain 5-7 cc.

Please note: A separate blood sample is required if a concurrent conventional blood chromosome and/or FISH studies are desired.

Do not freeze or “fix” samples in any manner contrary to the maintenance of cell viability. Maintain sample sterility, keep all specimens at room temperature, and deliver to the laboratory within 24-48 hours. Ship at room temperature for overnight delivery.
