In addition to aggregometer, low than normal levels of glycoprotein (GP) IIb-IIIa can be determined with flow cytometer using CD41 and CD61 monoclonal antibodies (Figure 1).
Platelet function testing by light transmission aggregometry: This was performed similarly to that previously reported, (16) using a Chronolog platelet aggregometer (Model 560-VS, Chronolog Corpora-tion, Havertown, PA, USA), with the stirrer speed set to 1000rpm.
