Study to Assess Platelet Dysfunction With Verify Now Assay

"In-vitro Characterization of Platelet Dysfunction in Common Hematological Disorders Using the Verify Now Assay"

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).

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.

Inclusion Criteria

- Patients with common blood disorders such as immune thrombocytopenia purpura(ITP) myelodysplastic syndrome MDS)and myeloproliferative disorders (MPV)

Exclusion Criteria

- Patients with normal platelet counts
