Trading update

Immunodiagnostic Systems Holdings plc ("IDS" or "the Company"), a leading producer of diagnostic testing kits for the clinical and research markets, announces a trading update for the six month period to 30 September 2010, prior to the release of its half-yearly report on Tuesday, 30 November 2010.

Turnover from continuing operations for the period is 34% ahead of the comparative period for last year at £22.6 million (2009: £16.9 million) and 11% ahead of 2009 H2 on a like for like basis.

The Company has made continued progress in placing instruments into reagent rental accounts as well as outright unit sales. At the end of September we had sold or placed 140 iSYS machines since it was launched in February 2009, almost doubling the number of machines in the market at our previous financial year end (as at 31 March 2010: 74 iSYS machines sold or placed).

Overall trading remains in line with management expectations and the Board remains confident going forward that it can continue to execute its plans for the current year.
