Molecular (genetic) testing is everywhere in medicine today, and the blood bank is no exception! Dr. Meghan Delaney is here to present 7 practical uses for molecular testing in Transfusion Medicine.You can hardly turn around in health care today without hearing someone talking about genetic testing (just to confuse people, such testing is more formally known as “molecular diagnostics” or “molecular testing”). In the blood bank, molecular testing is available right now, and it can really impact our day-to-day practice.
Meghan Delaney works right on the cutting edge of molecular testing. At the time of this interview, she was overseeing both a hospital transfusion service and an AABB-accredited immunohematology reference laboratory. Her unique experience allows her a great perspective on who should be using this testing and how it all fits together. This is a really enlightening discussion that may just open your eyes to some new possibilities!
