The NHS needs people who have recovered from COVID-19 to donate blood plasma, as part of a clinical trial to help with the national effort against the virus. The trial will provide information regarding how effective convalescent plasma (that is, plasma from people who’ve had COVID-19) is for treating coronavirus patients.

How you can help

Please register your interest in donating plasma if you have:

  • tested positive for coronavirus
  • tested positive for antibodies
  • had symptoms of the virus
  • understood our eligibility criteria
  • You can register your interest here. (Please note that not everyone will be able to donate: furthermore, we may need to contact you with more questions.)

Plasma can be donated from 28 days after recovery.

What is convalescent plasma?

Blood plasma is a yellowish liquid that makes up about half your blood volume. After a virus, your plasma contains antibodies that are used to help fight infection. Convalescent plasma is the antibody-rich plasma of someone who has recovered from a virus, in this case COVID-19.

Who can donate convalescent plasma?

Convalescent plasma can only be donated by someone who has had the virus. The NHS needs donors who have had a positive virus, a positive antibody test or symptoms.

It is also important that donors have fully recovered from COVID-19, and that their body has had time to develop a good antibody response. Please read more information about who can donate convalescent plasma.

Donating plasma

Plasma donation is not the same as blood donation: some donors will be asked to give a blood sample for testing. Other donors will be invited to give a full plasma donation. This means that more people can be assessed and high antibody donors found more quickly.

The process takes around 45 minutes and will separate plasma from the blood as you donate, in a process called apheresis.NHS staff will discuss the details of your donation before you take part.

You can travel to donate if there is a coronavirus local lockdown in your area. Travelling to donate plasma is classed as essential travel under government guidelines. The nearest donor centre to Trowbridge is located in Bristol.
