In the study, platelet count and volume, granulocyte number, binding o
f monoclonal antibodies to platelet glycoproteins Ibb and IIb/IIIa wer
e evaluated in hemodialyzed patients. Exclusively, the granulocyte cou
nt dropped significantly at 15 minutes after the initiation of dialysi
s as compared to predialysis samples. It seems that contemporary used
cuprophane dialyzer membrane is more biocompatibile and does not have
major impact on platelets.
