Recovered from COVID-19? Help current patients fight by donating plasma.

The South Texas Blood & Tissue Center is participating in a U.S. Food and Drug Administration (FDA) investigational program for blood centers to begin collecting and distributing convalescent plasma from individuals who have recovered from COVID-19.

While COVID-19 currently has no proven treatment, it is possible that convalescent plasma, which contains antibodies to the virus that causes COVID-19, may provide passive immunity to certain patients with severe forms of the illness.

Potential donors must be completely free of symptoms for 14 days prior to donation.

Recovered patients who meet these criteria along with all FDA requirements for blood and plasma donation can contact us about participating by clicking below.

Convalescent Plasma FAQs

The South Texas Blood & Tissue Center is not a COVID-19 “testing center” and is not doing widespread antibody testing. We are a blood center and are specifically collecting plasma from recovered COVID-19 patients, per FDA requirements, to be used as a treatment for patients who are currently sick with the virus.

I had COVID-19 symptoms but did not have a COVID-19 test. Can I donate convalescent plasma?

Certain individuals may have experienced symptoms before COVID-19 testing was available. In this instance some people may be eligible to be tested for COVID-19 antibodies for the purpose of donating convalescent plasma. This is possible if:

  • Your symptoms started no more than 45 days ago AND
  • You have been without symptoms for at least 14 days

If I meet the criteria to be a donor, what can I expect?

  • If you have a documented prior COVID-19 diagnosis and have fully recovered, we will send you a form for your physician or designee to complete. Once we receive that form, someone will follow up with you to schedule a donation appointment.
  • If you meet the qualifications for someone who has had COVID-19 symptoms but did not get tested, we will schedule a screening appointment for you. During the screening appointment, we will collect a blood sample to see if you qualify to be a donor.

I have a scheduled convalescent plasma donation appointment, what should I expect?

  • Come to your appointment well hydrated. Eat a good meal, but please avoid fatty foods.
  • Increase your calcium and protein intake prior to your appointment.
  • Your total appointment will take about 90 minutes. This includes a 15-minute health screening and 60-75 minutes on the plasma collection machine.
  • After your initial donation, you will be eligible to donate every four (4) days if you are feeling well and if there is no decrease in your blood protein levels.

How many patients can my donation help?

A single dose of convalescent plasma is 200mL. On the average, one donor can provide 3 – 4 doses, which can help treat 3 – 4 people.
