Study of Blood Platelets in Sickle Cell Disease

Status Withdrawn

Clinical Trial Summary

We are studying if sickle cell disease blood platelets are larger than normal and how they may cause obstruction of blood vessels. We are also trying to study the reasons why large platelets are found in patients with sickle cell disease.

Clinical Trial Description

Research volunteers are seen in the Outpatient Research Center by the Principal Investigator or another physician. A detailed history is obtained, a physical examination is performed, and blood (usually 4 tablespoons) is obtained for additional tests. The research volunteer's previous medical records will be requested. Upto 5 additional blood samples may be obtained in a subgroup of patients. ;
