September 11, 2017 updated by: Shimaa Abdeleem
Platelet units are stored and complement factors are evaluated

Study Overview

Status

Unknown

Conditions

Detailed Description

Ten units of platelets will be selected from the regular inventory of the Central Blood Transfusion Services/Assiut University Hospitals . All units of platelets will be collected, processed, and tested following the standard procedures.

Thesis units will be stored on a platelet rotator with the temperature controlled between 22 and 24c. Samples will be obtained using a sterile technique .

The investigators will take basal sample and samples on day 2,3,4 and 5. Complement components will be assayed : C4 (classical pathway), C3 (common pathway) and C5 (terminal pathway).
