For a limited time, the American Red Cross has resumed testing all blood, platelet and plasma donations for COVID-19 antibodies.

Plasma from routine donations that have high levels of COVID-19 antibodies may be used as convalescent plasma to help meet the needs of COVID-19 patients with weakened immune systems.

At the same time, the Red Cross blood supply remains vulnerable, and individuals are urged to schedule a blood or platelet donation. To make an appointment, use the Red Cross Blood Donor App, visit RedCrossBlood.org or call 1-800-RED CROSS (1-800-733-2767).

The Red Cross is not testing donors to diagnose illness, referred to as a diagnostic test.

Those who come to give blood or platelets in March will receive a $10 e-gift card, sponsored by Fanatics. Plus, donors will also automatically be entered for a chance to win a trip for two to the 2022 Major League Baseball All-Star Game in Los Angeles.
