§ Mr. PatersonTo ask the Secretary of State for Environment, Food and Rural Affairs (1) what assessment she has made of why the gamma interferon test achieves sensitivity of 60 to 65 per cent. in UK trials; [158363]
(2) what assessment she has made of the difference in gamma interferon test sensitivity in UK trials compared with test sensitivity in Australia. [159120]
§ Mr. BradshawThe gamma-interferon pilot currently running in Wales, Staffordshire, Cheshire, Derbyshire, Herefordshire, Worcestershire and Shropshire, and the work carried out in Northern Ireland, have not been designed to assess the sensitivity of the gamma-interferon test. No comparisons can therefore be drawn with test sensitivity in trials run in other countries.
