Immune Thrombocytopenia (ITP)

The McMaster Platelet Immunology Laboratory provides investigation for autoantibodies in patients with ITP using assays that measure antibodies to specific platelet glycoproteins, as opposed to measurement of platelet‐associated antibody which has a poor specificity and is generally uninformative1.  Platelets from patients with suspected ITP and tested directly for glycoprotein-specific antibodies, including antibodies directed to platelet GPIIbIIIa and GPIbIX.

Test Methods:

Glycoprotein‐specific Monoclonal antibody‐based EIA
