Several thousand schools and medical centers in the United States are named after the iconic doctor. Drew paved the way for blood plasma to be widely used with his pioneering research and findings. The Columbia University grad student found that plasma from blood required both centrifugation and liquid extraction. The extraction had to be done under a controlled environment to avoid contamination. Drew used the techniques of air concealment, ultraviolet light and merthiolate to store plasma safely from contamination. He applied his findings and techniques to aid in mass blood preservation and transportation. This method made it possible for mass blood plasma and transfusions to be successful in Europe, the United States and globally.
