Donation of Convalescent Plasma

Convalescent Plasma for the Treatment of COVID-19 and Donation of Convalescent Plasma

April 13, 2020

Use of convalescent plasma to treat COVID-19 patients

  • People who've recovered from COVID-19 have antibodies to the disease in their blood. Doctors call this convalescent plasma. COVID-19 convalescent plasma has not yet been demonstrated to provide clinical benefit in patients affected by this disease. It is not known if this treatment will or will not help those with COVID-19 or if it will have any harmful effects. Based on preliminary data from small series of patients it appears safe and historical precedent with other respiratory infections the antibodies in convalescent plasma may provide therapeutic benefit.

The following pathways are available for the use of COVID-19 convalescent plasma:

  1. Clinical Trials: Information regarding clinical trials involving use of convalescent plasma is available at Not every clinical trial is registered on the website1; other clinical trial options may be available.
  2. Single Patient Emergency IND: The FDA is facilitating access to COVID-19 convalescent plasma for use in patients with COVID-19 infections through a single patient emergency IND (eIND) for the individual patient. For more information, see:
  3. Expanded Access Treatment Protocols: Currently, the Mayo Clinic is the lead institution for the only expanded access protocol approved by the FDA. This protocol targets adults admitted to the hospital with severe2 or life- threatening illness:

National Expanded Access Treatment Protocol (

Physicians must register their institution in Mayo Clinic's database in order to obtain access to convalescent plasma for their patients under this protocol. To participate, your hospital can rely on the Mayo Clinic IRB. A separate IRB reliance agreement is not required. Hospitals can designate one physician/PI for this Expanded Access Program OR multiple physicians/ PIs can
register for each site.

1 Note: Not all clinical trials are registered on the website.
2 Severe COVID-19 is defined by > 1 of the following: shortness of breath, respiratory rate ≥ 30/min, blood oxygen saturation ≤ 93%, partial pressure of arterial oxygen to fraction of inspired oxygen ratio < 300, lung infiltrates > 50% within 24 to 48 hours.

As of April 13, 2020, over 50 Illinois hospitals have registered to participate in this protocol.

Expanded Access Treatment Protocol links:

  • Site Registration Form (first step, also includes IRB information)
  • Physician/PI Registration Form (use only after registering your hospital)
  • Patient Enrollment Form(use only after the above steps have been completed and patient has consented)

For more information, go to the Expanded Access Program website, or contact the PI at

Donation of convalescent plasma by recovered COVID-19 patients

Convalescent COVID-19 Plasma will be widely available under the above programs only if there is robust participation of recovered patients in the plasma donation process. Hospitals may choose to support donation by contacting and referring recovered patients.

Donors may donate as 14-27 days after they have recovered to donate if they have a negative nasal, nasopharyngeal or blood molecular assay. If donors wait for ≥28 days after recovery repeat testing to document a negative specimen is not typically required, and higher antibody levels are usually present.

Alphabetic list of links to current information regarding donation of convalescent plasma through blood donation centers:

  1. Central Illinois Community Blood Center
  2. Red Cross:
  3. Versiti:
  4. Vitalant Patient Self-Referral:
  5. Rock River Valley Blood Center

Additional information regarding facilitation of donation by recovered patients will be provided in a forthcoming memo.
