More members of the West Midlands' ethnic communities are being urged to give blood.
Asian, African and Afro-Caribbean people are six times less likely to know what their blood group is compared to the national average.
Last year 1.6 million Britons gave blood, representing just five per cent of the eligible population, of which only three per cent were from the country's ethnic communities.
Despite Birmingham having nearly one million ethnic residents, less than one per cent are registered donors. Last year, across the West Midlands more than 1,000 new Asian, African or Afro- Caribbean donors signed up, but many more are needed.
Two donor sessions are being held on September 7 at the UCKG Help Centre, in Lozells Road, Birmingham, between 12.30pm and
2.45pm and 4pm and 6.15pm.
Lyndsay Stewart, of the National Blood Service said: "This issue is pertinent because a number of blood types are more common and specific to people from certain ethnic backgrounds.
"For example, 25 per cent of Asians are blood group B compared to eight per cent of western Europeans.
"In the West Midlands we are trying to make it easier for people to donate by holding sessions in temples, mosques and community centres, in addition to our regular venues, so that people can donate somewhere convenient for them.
"It's vital that we get our message across to everyone within ethnic communities that donating blood is quick, safe, easy and could save a life."
