The plasma donation center in Kalamazoo saw a six-month high in January with 3,500 donors. The Quality Supervisor, Paulette Brooks, attributes the increase to the center's new location closer to downtown, which has a more positive perception than the previous location. Brooks' job is to ensure every donated plasma sample meets quality standards through rigorous testing and record keeping. Her days involve multi-tasking between tasks like reviewing samples, training employees, and communicating with other facilities to maintain the high quality of plasma products.
