Drew won an athletics scholarship to Amherst College in Massachusetts , [ 9 ] where he played on the football as well as the track and field team, and later graduated in It was during this stage in his medical journey that Drew worked with John Beattie, who was conducting research regarding the potential correlations between blood transfusions and shock therapy.

As the body goes into shock, both blood pressure and body temperature decrease which then causes a lack of blood flow and a loss of oxygen in the body's tissues and cells. Eventually, it became clear that transfusions were the solution to treating victims of shock, but at the time there was no successful method of transportation or mass storage of blood, leaving transfusions to be extremely limited to location.

At McGill, he achieved membership in Alpha Omega Alpha , a scholastic honor society for medical students, ranked second in his graduating class of students, and received the standard Doctor of Medicine and Master of Surgery degree awarded by the McGill University Faculty of Medicine in Drew's first appointment as a faculty instructor was for pathology at Howard University from to In , Drew began graduate work at Columbia University in New York City on the award of a two-year Rockefeller fellowship in surgery.

He spent time doing research at Columbia's Presbyterian Hospital and wrote a doctoral thesis, " Banked Blood: A Study on Blood Preservation ," based on an exhaustive study of blood preservation techniques. When ready for use the plasma would then be able to return to its original state via reconstitution. Drew died without ever being accepted for membership in the AMA.
