Abstract
A whole blood control sample and a method of preparing the sample are disclosed. The method comprises collecting a whole blood sample from one or more donor, separating each sample into red blood cells and plasma, fixing the red blood cells, mixing the fixed red blood cells with plasma from the same or a different donor to produce a suspension, quick-freezing the suspension before the red blood cells can settle, and lyophilizing the frozen suspension. The control sample therefore comprises a lyophilized mixture of fixed red blood cells and plasma solids.
