BLOOD BANK (Blood contamination and causes)

Dr Ho Tat Kin asked the Acting Minister for Health what percentage of blood collected by the Blood Bank in 1986 and 1987 could not be used because of contamination; what were the main causes of the contamination; whether the percentage has been on the increase; and what does his Ministry do with the contaminated blood.

Mr Yeo Cheow Tong: Sir, the percentage of blood collected by the Blood Bank in 1986 and 1987 that was contaminated and could not be used, was 2.3% and 2% respectively.

The main causes of the contamination were Hepatitis B virus and syphilis.

The level of contamination has been fairly stable, fluctuating around the 2% mark.

The contaminated blood is sterilized in an autoclave to destroy all bacteria and viruses and then disposed through the sewer.

Dr Ho Tat Kin (Boon Teck): Sir, are those who donate contaminated blood notified by the Ministry for follow-up treatment?

Mr Yeo Cheow Tong: Yes. Those with either Hepatitis B or syphilis are informed that their blood is contaminated and they are advised to either go to their family doctor or seek treatment at our Middle Road Clinic.

Mr Chiam See Tong: Mr Deputy Speaker, Sir, is there a possibility of receivers getting contaminated blood?

Mr Yeo Cheow Tong: Mr Deputy Speaker, Sir, our blood supply is one of the safest in the world, if not, the safest. We take great care to analyse all blood donations to ensure that the blood that is being transfused is free from contaminants.
