Do you support receipt of fresh whole blood directly from clinical sites?

Yes, if samples arrive at our facility within 48 hours of collection. Blood stored at room temperature for 24 to 48 hours shows modest changes in marker expression, but dramatic changes by 72 hours. Temperature fluctuations during shipping and delivery delays are other factors that can impact fresh blood samples. For this reason, we highly recommend fixing blood on-site using our TokuKit and shipping samples on dry ice to preserve marker expression and sample quality during shipping.
