Brief Summary:
The purpose of this study is to conduct a Verify now assay to detect platelet aggregation defects in patients with Myelodysplastic syndrome(MDS), immune thrombocytopenia purpura (ITP) and myeloproliferative disorders (MPD).

Condition or disease
Platelet Aggregation Defects

Detailed Description:
Verify Now is a rapid, simple, point-of service assay to measure platelet aggregation. The verify now assay is designed to assess platelet function based on the ability of activated platelets to bind fibrinogen. It is hoped that this study will detect the subtle platelet functional abnormalities in patients with hematological disorders.
