§ Mr. Kirkwoodasked the Secretary of State for Social Services for each year since 1981–82 (a) how much factor VIII was used in England and Wales, (b) what proportion of this was supplied by Central Blood Laboratories Authority institutions and (c) what proportion was supplied by the Elstree blood products laboratory.
§ Mr. WhitneyThe estimated total consumption of factor VIII of all types in England and Wales has been as follows:
Millions of Units Calendar Year Total Used* BPL Proportion† Production‡ per cent. 1981 57.6 20.8 36.1 1982 65.3 22.0 33.6 1983 62.3 30.8 49.4 1984 69.6 27.9 40.0 Notes * Most of this factor VIII was in the form of factor VIII concentrate, but the total includes some units used in the form of cryoprecipitate and plasma produced by regional transfusion centres.
† The blood products laboratory (BPL) is a constituent part of the Central Blood Laboratories Authority (CBLA). It is the BPL which produces blood products at its Elstree and Oxford sites. The CBLA has a management function only. BPL supplies factor VIII concentrate only.
‡ Production and consumption figures are not strictly comparable since output in any one year may not be consumed that same year.
§ Mr. Kirkwoodasked the Secretary of State for Social Servies why, between 1983–84 and 1984–85, the output of factor VIII from central blood laboratories institutions fell by 2 million units.
§ Mr. WhitneyProduction of non heat-treated factor VIII stopped during the course of the first quarter of 1985 whilst rapid preparations were made to introduce a safer heat-treated product.
