About This Item

 

Full Description

ISO 17994:2004 defines an evaluation procedure for comparing two methods intended for the detection or quantification of the same target group or species of microorganisms.

ISO 17994:2004 provides the mathematical basis for the evaluation of the average relative performance of two methods against chosen criteria of equivalence.

Any two enumeration methods based on counts (of colonies or positive tubes) or any two detection methods (presence/absence methods) intended for the same purpose can be compared.

ISO 17994:2004 provides no solution to directly compare a quantitative method (colony count or MPN) with a detection method (P/A).
