DENVER (KDVR) – Vitalant and the Denver Sheriff Department held a blood and convalescent plasma drive Wednesday.

Convalescent plasma is plasma donated by people who have fully recovered from the COVID-19 infection, according to the Colorado Department of Public Health and Environment (CDPHE).

The plasma contains antibodies that might be useful in treating current coronavirus patients, CDPHE said.

More than two-dozen people donated convalescent plasma during the drive.

All blood donations are tested for COVID-19 antibodies, according to Vitalant.
