    THE INVESTIGATION FOR FIELD ACTION FA13SEP2010 DETERMINED THE ROOT CAUSE OF ARCHITECT IVANCOMYCIN (LIST NUMBER 01P30-25) FOR FALSELY ELEVATED RESULTS IS DUE TO THE TRACER DILUENT FORMULATION. THE FORMULATION DOES NOT ADEQUATELY PROTECT AGAINST SPECIMEN CONTAMINATION. THE INVESTIGATION DETERMINED, AND SUBSEQUENT VERIFICATION CONFIRMED, A CHANGE TO THE CONJUGATE DILUENT WILL CORRECT THE ISSUE RELATED TO FALSELY ELEVATED RESULTS DUE TO CONTAMINATION, AND WILL ELIMINATE THE NEED FOR CUSTOMERS TO PERFORM ADDITIONAL SAMPLE CENTRIFUGATION AS INSTRUCTED IN PRODUCT CORRECTION LETTER OF FA13SEP2010. A PRODUCT INFORMATION LETTER REGARDING THIS NEW REAGENT WAS ISSUED ON (B)(4), 2012 INFORMING EX-US CUSTOMERS THAT THE NEW REAGENT FORMULATION, LIST NUMBER 1P30-27 WILL BE AVAILABLE (B)(4), 2012. THE ADDITIONAL SAMPLE CENTRIFUGATION AS INSTRUCTED IN PRODUCT CORRECTION LETTER OF FA13SEP2010 WILL CONTINUE TO BE FOLLOWED BY US CUSTOMERS. SUBMISSION FOR THE US 510K CLEARANCE OF THE NEW PRODUCT WILL OCCUR THE (B)(4) OF 2012.
