Return
Use the pre-paid FedEx label and polystyrene box in the kit.
Analyze
RNA is extracted and quantified by RT-PCR at our CLIA/CAP lab in Branford.

At least 2 mL of blood should be drawn into the provided tube, with appropriate patient identifiers on the tube. Once collected, either send the sample within 24 hours or freeze it at −80 °C (not a normal refrigerator freezer) until send-out. Send on the same or next day using the kit provided.

For studies that batch-send samples: freeze all collected tubes at −80 °C within 24 hours of collection. Once sufficient samples are collected (e.g., 20), send by courier at ambient temperature using the kit box provided.
