In England, which began roll-out of its screening programme in April 2006, a weakly positive FOBT is followed by a repeat FOBT. Colonoscopy then follows.
Wales plans to begin roll-out of a similar scheme in April. Northern Ireland is working towards introducing a screening programme in 2009.
Last year, researchers from the Scottish Bowel Cancer Screening Laboratory in Dundee showed that using FIT in this way could reduce the need for colonoscopy by 30 per cent (GP, 13 January 2006).
