Figure 2From: Shipping blood to a central laboratory in multicenter clinical trials: effect of ambient temperature on specimen temperature, and effects of temperature on mononuclear cell yield, viability and immunologic functionThe recovery of cells after Ficoll separation increased as shipping temperature increased. (A) Correlation of the ratio cell yield with minimum temperature during transport; p = 0.001. (B) Correlation of the ratio cell yield with maximum temperature during transport; p = 0.04. (C) Correlation of the ratio cell yield as a function of maximum temperature deviation from room temperature (22°C) during shipment; p < 0.001Back to article page
