Your blood could save lives

The antibodies of fully recovered COVID-19 patients could help fight infection in those still suffering from it. The only source of these antibodies is the blood plasma of coronavirus survivors. See this FDA video for a quick introduction.

Giving blood plasma to a COVID-19 patient from a person who has healed from it might help the sick person get better faster. But we need more of this plasma to find out. 

 The CDPH sent letters to Californians who tested positive for coronavirus to encourage them to donate blood plasma.

Your blood plasma donation could help up to 4 people suffering from COVID-19.

Who can donate COVID-19 plasma?

  • A person who had a test that showed coronavirus infection,
    AND
  • Has felt well for at least 28 days*,
    AND
  • Passes the usual rules for blood donation. 

*If you want to donate before one month has passed since you recovered, please check with your blood center. Some centers will need a negative swab test, and may have other rules.

What are the risks?

It is generally very safe for people to donate blood plasma. Your local blood donation center can tell you more about the risks and benefits of donation.

Donating is voluntary. Your decision to donate or not will not change your eligibility for medical or public health services. 

CDPH is not a participant or sponsor of research for COVID-19. It is supporting the work of medical providers across the state by inviting you to donate your blood plasma.
