A difference of ≥5 mm between the zone diameters of either of the cephalosporin disks and their respective cephalosporin/ clavulanate disks is taken to be phenotypic confirmation of ESBL production، is this true? A clear extension of the edge of the inhibition zone of cephalosporin towards augmentin disk is interpreted as positive for ESBL production. Is this regardless of how many extend this clear zone, I mean we saw a resistance for AMC and also for CAZ for example, but there is a synergy zone between them, then is it consider an ESBL positive? Please explain it to me more if i wrong, thanks a lot for your efforts.

Exactly

I was lost at the confirmatory test

1:22 shows two methods of ESBL, the screening and confirmatory. If screening is negative, stop here. If it is positive go to confirmatory test which includes two disks the cephalosporin and the cephalosporin+ clavulanic acid disk
