SAN ANTONIO – Despite the U.S. Food and Drug Administration’s recent update on the use of COVID-19 convalescent plasma, the South Texas Blood and Tissue Center is still encouraging people who are eligible to donate.

In February, the FDA narrowed its requirements for donors and recipients after reviewing findings from clinical trials. Some found patients did not benefit from receiving convalescent plasma. Others showed they only benefitted during specific circumstances.

“Initially, it was a larger group of patients that could get convalescent plasma. Now, with the recent revision, it’s limited to hospitalized patients early in the course of the disease,” said Dr. Samantha Gomez Ngamsuntikul, associate medical director at STBC.
