Abstract: Objective To observe the influence of pneumatic tube system（PTS） on the partial functional parameters of red blood cells and platelets in blood. Method Thirty bags of whole blood in storage for 5 days was used, 450ml each. The blood was randomly divided into damping group and non-damping group, with 15 bags in each. Parameters of the blood cells before and after PTS transportation were measured by ELISA. Result The markers of 2,3-DPG, G6PD, sodium-potassium ATPase, CD55, CD59, GP-Ibβ, β-TG, PF4, and P-selectin were examined in damping group before and after transportation and compared with those in non-damping group. As a result, no significant difference was seen between the two groups (P>0.05). Conclusion PTS transportation for whole blood have not distinct and instant damage to red blood cells and platelets in stored whole blood.
