Hospitals in Sweden are facing a shortage of blood due to increasingly advanced healthcare techniques, according to a top hospital doctor.
Operations at the Uppsala University Hospital were suspended due to the scarcity of blood, reports United Press International.
The hospital's chief physician Johan Ronnelid said that the shortage is most severe in O and B blood groups.
"There is a shortage of blood in the whole country," said Ronnelid.
He said the shortage is due to increasingly sophisticated medical techniques which require larger quantities of blood.
Hospitals are now increasing efforts to get supplies from remote locations.
