Plasma donors sought among recovered COVID-19 patients

UW Medicine, Bloodworks Northwest researchers to investigate potential new therapy: plasma-derived medicine.

UW Medicine and Bloodworks Northwest are seeking adult volunteers who have recovered from documented SARS-CoV-2 (COVID-19) infection to be considered for donation of plasma. 

Plasma is the liquid component of blood that contains various proteins. Antibodies are proteins in plasma that defend your body against infections. Donated plasma can be used to make medicine containing antibodies to treat people who are fighting a severe infection or who cannot make antibodies on their own. Plasma and medication made from it are used routinely to treat many different diseases. It is unknown whether the antibodies in plasma from people who have recovered from COVID-19 can help people who are ill with a COVID infection.

“We are excited about moving forward in this time of a serious pandemic to develop a potential new therapy for this infection,” said Dr. Terry Gernsheimer, a professor of medicine (hematology) at the University of Washington School of Medicine. She and Dr. Anna Wald, UW professor of medicine, epidemiology and laboratory medicine, are co-lead investigators, working with Dr. Rebecca Haley, medical director of Bloodworks Northwest’s apheresis center.

Plasma is collected by plasmapheresis, a process with a specialized medical instrument that separates plasma from the cells in the blood. This safe and sterile process collects the plasma, while remaining blood (including red blood cells and white blood cells) is returned to the plasma donor. The body rapidly replaces the plasma and the proteins that are removed, so people can donate once every two weeks.

The researchers will evaluate recovered patients’ antibody levels and general health to ensure that study prospects are good candidates to donate plasma.

“We also hope to gather demographics about COVID-19 survivors to see if there are meaningful associations, and discern as best we can how those antibodies contributed to their recovery. Eventually we want to tie the donors’ characteristics with outcomes in patients who receive infusions of plasma. This study protocol does not address that, but a longer-term project would,” Gernsheimer said.

If you are in general good health and have recovered from a COVID-19 infection, you might be able to help.  Your first visit would be at the University of Washington Virology Research Clinic to assess your health and confirm your COVID-19 infection.  At that visit, blood would be drawn to see whether you would qualify to be a plasma donor. Depending on the results, you may be invited to make an appointment at Bloodworks Northwest for further screening to become a plasma donor.

If you might be interested to participate, please email your name and contact information to or call 206.520.4212 to leave a message.
