DREW’S METHOD OF SEPARATION

How plasma was taken from blood

1 Separation Drew and his team used centrifugation and sedimentation to separate plasma from the blood.

2 Extraction Plasma was then removed and pooled together under ultraviolet light to prevent contamination.

3 Bacteria To prevent bacteria infiltrating the batches of blood, an anti-bacterial called Merthiolate was added.

4 Storage Plasma was then diluted with saline solution and sealed for shipping.
