The Blood Center begins COVID-19 antibody testing on all blood donations

News

BATON ROUGE, La. (BRPROUD) – The Blood Center is now testing all blood donations for COVID-19 antibodies, informing donors if they have the antibody used in plasma transfusions that may help patients who are critically ill with the virus.

Donors who test positive for COVID-19 antibodies may be eligible to donate COVID Convalescent Plasma, according to The Blood Center spokesman Paul Adams.

“We’ve seen promising results from patients who’ve received CCP, but there’s only a few recovered patients who are eligible to give at this time” The Blood Center Medical Director Dr. Tim Peterson said. “The scarcity of donors with the COVID antibody make this test extremely beneficial to patient care.”

It’s not safe to assume that those who do have the antibody are immune to the virus, Adams wrote.

“The serology test has a specificity greater than 99.8% and sensitivity of 100%,” Adams wrote. “The high specificity of the test is crucial to determine reliably if a person has been exposed to the virus and if the patient has developed antibodies.”
