Convalescent plasma

As of July 16, CBC is conducting the coronavirus antibody test on blood, platelet and plasma donations to identify possible convalescent plasma donors. This testing will help us potentially identify more donors who can help patients suffering from the coronavirus. The coronavirus antibody test is one of the more than 12 tests performed on every unit as we prepare blood for clinical needs.

If you are recovered from COVID-19 and want to learn more, please complete the convalescent plasma interest form and a member of our team will be in touch soon.

Convalescent Plasma Form

Notification of test results:

  • If antibodies are detected in your blood sample, you’ll receive a letter in the mail 7-10 days after donating. This letter will contain information about the antibodies and next steps for becoming a convalescent plasma donor. Upon receipt of the letter, we encourage donors to call with questions or to schedule a convalescent plasma donation. Please note: due to the special nature of this donation type, appointments must be made over the phone and cannot be scheduled online. Please call (920) 560-6630 to schedule a convalescent plasma donation.
  • CBC only notifies blood donors of test results when they are positive. It is possible your unit may not be tested for the coronavirus antibodies. If you are not notified of a positive test result indicating the detection of coronavirus antibodies, you should not assume you had a negative test result.

Additional information related to the use of convalescent plasma:

  • COVID-19 convalescent plasma has not been approved or licensed by FDA;
  • COVID-19 convalescent plasma has been authorized by FDA under an EUA;
  • COVID-19 convalescent plasma is authorized only for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of drugs and biological products during the COVID-19 pandemic under section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the authorization is terminated or revoked sooner.

Blood donation is an essential service to the community

Cancer does not stop. Chemotherapy cannot get rescheduled. Emergency surgery still happens. Our community will continue to rely on volunteer blood donors in the coming weeks and months, because there is no substitute.

Blood centers and blood donors are recognized as essential critical infrastructure during the response to COVID-19.

Under the Department of Homeland Security, the Cybersecurity and Infrastructure Security Agency (CISA) has listed blood donors as essential. Their guidance document outlines the importance of blood donation, blood banks and blood donors to public health.

Safety is the Top Priority

Here’s what we’re doing to ensure the safest donation environment possible:
