From: 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 function

Figure 1

Recorded internal package temperatures during shipment and cell yields of blood from off-site cancer centers. (A) High (+) and low (●) package temperatures recorded between August, 2005 through April, 2006. (B) Yield of PBMC (cell yield) obtained from specimens shipped during this time after Ficoll separation. The ratio cell yield is expressed as a ratio of total number of PBMC collected after Ficoll divided by the number of PBMC (lymphocytes and monocytes) estimated from the differential WBC recorded on the same specimens before shipment. The dashed line represents 100% recovery of PBMC after Ficoll as a ratio cell yield of one.
