§ Mr. Carter-Jonesasked the Secretary of State for Social Services what tests are carried out on blood that is used for transfusions.
§ Mr. Kenneth ClarkeBlood used in transfusions is grouped, screened for antibodies and tested for hepatitis B surface antigen and syphilis. Before a blood donation is taken the donor has a haemoglobin test and a medical history is taken both for the sake of the donor's health and to exclude, as far as possible, the collection of blood which might transmit infection or contain drugs such as antibiotics.
