The number of people receiving plasma as a treatment for COVID-19 has quadrupled in the last month.
Around 220 hospitalised patients were treated in September as part of clinical trials that began in May.
People who have had coronavirus produce antibodies that are present in their plasma – if transfused to a COVID-19 patient who is struggling to develop their own immune response, there is evidence that it could help them recover.
NHS Blood and Transplant currently holds enough units of donated plasma for the trials – but is building a stockpile that is ready to be used immediately if the trials succeed.
The NHS currently has enough units to treat about 4,000 people and is appealing for more donations.
Sheila MacLennan, clinical lead for the Convalescent Plasma Programme, believes the increase in treatments is due to more hospitals participating in the trials and an uptick in coronavirus cases.
Professor Jonathan Van-Tam, the deputy chief medical officer, urged people to donate plasma and volunteer for clinical trials.

"I like to think it helped, though the trial is still going on," he said. "My son is a doctor with some experience of it and he thinks it helped."
Mark Campanale, 56, runs a research NGO and has donated plasma six times since he got COVID-19 in March.
After initially dismissing his high fever as "summer flu", he became delirious and was taken to Kingston Hospital, where he received oxygen treatment for five days.
He started donating plasma a few weeks after he recovered and hopes his antibody levels will remain high enough for him to continue doing Read More – Source
