An antimicrobial susceptibility assay, including the steps of: providing an assay dish; providing a growth medium in said dish; providing an antimicrobial agent sample; providing an interpretive indication located a predetermined distance from a sample location adjacent the growth medium in the assay dish; providing an interfitting element which interfits with said dish, said interfitting element configured to enable at least one the steps of: a) more accurately positioning the antimicrobial sample at the sample location in contact with the growth medium; b) providing the interpretive indication at a predetermined distance from said sample position to enable said interpretative indication to be compared with a margin of a zone of inhibition of a colony grown on said medium to determine an assay result, wherein said result can include determination of at least one of: a) "susceptible;" "intermediate;" and, "resistant;" placing a microorganism on the growth medium; placing the antimicrobial agent sample at said sample location with accuracy using said interfitting element; incubating said microorganism for a period sufficient to allow a margin of a zone of inhibition to be discernable; and, comparing the location of the margin of the zone of inhibition to the interpretive indication, to obtain a result including a determination of at least one of a) "susceptible;" b) "intermediate;" and, c) "resistant" for said microorganism with respect to the antimicrobial agent.
