A majority of the blood donated will be given to cancer and blood disease patients who need treatment during the holiday season.

Cheryll Koop has made more than 22 donations of her rare AB- blood type to help others and was surprised to learn the Dubbo Blood Centre on Darling Street was open on Christmas Eve.

"You can use my donation with everyone," she said.

"You can give plasma to more people and you can give every two weeks."

Gabrielle Pearson gave blood after travelling 10 hours from Hidden Valley in Victoria to celebrate Christmas with her family

"I rang up to book in here for my community service I like to do," she said. "I usually come in before Christmas because it is advertised."

Dubbo Donor Centre spokesperson Helen Woods said platelets were vital to the treatment of cancer patients.

"We know the holiday period is an important time to spend with family and friends but spare a thought for the many Australians who have a loved one in hospital and in need of blood," she said.

"With two public holidays and a weekend, it is vital that Dubbo donors maker an appointment to give blood after Boxing Day to help replenish platelet stocks."

"Every donation helps to save as many as three lives, and this holiday period is the perfect time to give back to the community."

The Dubbo Donor Centre is open on December 27, 28, 29 and 31. In the new year it is open on January 2, 3, 4 and 5.
