Plasma from convalescent COVID-19 patients has been all over the news as a proposed treatment for coronavirus, with the hope that antibodies in the plasma can neutralize the virus and prevent entry into cells.

While studies into the safety and effectiveness of this treatment approach are ongoing, convalescent plasma is also needed to drive research into the pathology and potential vaccines for COVID-19.


How Convalescent Plasma Can Help

Mononuclear cells and plasma collected from convalescent donors may provide an opportunity for researchers to more completely evaluate the range of immune response to SARS-CoV-2 infection, ultimately leading to important advancements in the development of therapies and vaccines to combat this virus.

Plasma samples from convalescent COVID-19 patients can be used in research and development to test the accuracy and reproducibility of antibody assays and to further understand the range of antibodies against the virus in different individuals.


About COVID-19 Plasma Donors

We are actively collecting plasma and PBMC from subjects who have recovered from SARS-CoV-2 infection. All collections are carried out safely according to IRB-approved protocols in our collection facilities. See a list of frequently asked questions about our COVID donors below.

How do you confirm a patient’s positive COVID-19 test?
All convalescent donors must provide proof of a positive laboratory diagnostic test for COVID-19.

How do you report on donor infection and recovery status?
The “time since infection” and “time since negative results” are recorded for each product as well as the neutralization titer information.

Are your COVID donors screened for other pathogens?
Yes. All donors undergo standard blood tests required for any blood donation. Additionally, convalescent COVID-19 donors must have an acceptable health history, pass a physical assessment, and undergo a COVID-19 antibody blood test to confirm status.

What collection protocol do you use?
We follow an IRB-approved protocol to support the research, therapeutic, and vaccine communities with much needed access to blood products collected from COVID-19 convalescent donors.

Where are convalescent COVID-19 collections performed?
In our Lowell, MA and Memphis, TN locations.

How do you ensure safety during collection?
All in-person activities include CDC recommended screening and social distancing measures for donor protection. All donors must be recovered, may not be taking any medications for COVID-19, and must be officially out of quarantine.

“Individuals who have recovered from COVID-19 can provide a small amount of their blood to support critical research that may help others who acquire the infection have a greater chance of recovery or lead to development of effective vaccines to prevent it.”
-Dr. Edward Scott, Chief Medical Officer, Cellero
