§ Mr. Ian Lloydasked the Secretary of State for Social Services (1) whether he will describe the costing of immunodiagnostic testing in the National Health Service, public health and blood transfusion service laboratories, with particular reference to the recent criticism of current procedures;
(2) what information he has on the rate at which immunodiagnostic testing employing radioactive isotopes is being replaced by commercially available products which do not require such isotopes.
§ Mr. HayhoeI regret that this information is not available centrally, and I am not aware of the criticism to which my hon. Friend refers.
