MUSCAT, Aug 29 – Are you ‘O’ positive? Do you meet all the blood donation requirements? Then, head to the Central Blood Bank (CBB) in Bausher, which needs blood for a liver transplant surgery scheduled to take place at Royal Hospital next week. “We need more blood as the demand is growing these days. We need O+ blood for a major liver transplant happening next week,” said a CBB source. Any citizen who has not visited the yellow fever affected countries or expatriates (who have not travelled home in the last one year) can donate. The CBB, under the Ministry of Health, has urged ‘O+’ donors to visit the blood bank on any day, except weekends, between 8 am and 8 pm, to donate blood. “We get five to six units of blood every day from Qurayat, thanks to some good Samaritans there,” said the source.
