Your blood could save lives

The antibodies of COVID-19-recovered patients could help fight infection in those still suffering from it. The only source of these antibodies is the blood plasma of coronavirus survivors. 

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 California Department of Public Health has mailed letters, including translation in seven languages, to encourage Californians who have had a positive test to consider donating their plasma to help develop treatments for COVID-19.

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,
  • Has felt well for at least 28 days*,
  • 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 require 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. 

The California Department of Public Health (CDPH) is not a participant or sponsor of research for COVID-19, but is supporting the work of medical providers across the state by inviting you to donate your blood plasma.
