National Blood Transfusion Center deputy director Hok Kim Cheng says
that the center considers blood to be safe after testing it for
HIV/Aids, hepatitis, and transmitted social diseases such as syphilis.
About ten percent of the blood was found tainted in some way, he said,
and was destroyed.
Safe blood was then classified by type (A, B, O, and A&B) and could
then be refrigerated and stored for up to 35 days, he said.
Blood donated by high school and university students or by Buddhist
monks was considered the lowest-risk compared to blood from
professional donors or military personnel.
There was some small danger, he said, because the test for HIV/Aids
would sometimes not reveal HIV in the blood of patients exposed to it
within the past three months. The risk, however, has so far been small,
with no cases of HIV infection attributed to this cause.
“Usually the demand for blood is about 3,000 units per month, so we
encourage people to donate blood in case their relatives or family
members need it. We encourage people to understand that donating blood
won’t harm their health in any way,” said Hok Kim Cheng.
The current blood supply was nearly enough to meet demand, and there was no serious shortage, he added.
