Tom Cibotti, a Managing Director at Covington Associates, was quoted as saying “We continue to enjoy our longstanding advisory relationship with Inverness Medical, as the Company continues its expansion in the cardiology rapid diagnostics field.  The recent pending acquisitions of Cholestech and Biosite, among others, are transforming Inverness into a leading player in the professional point of care rapid diagnostics arena.”
