Numerical values are expressed in µg/ml.

§ Equivalent standard method concentration by efficacy.

**CSAGNB = Clinically significant aerobic gram negative bacilli

= Category agreement was established at the time of FDA clearance. Essential agreement was not established since

test contains less than five discrete dilutions.

**Kox(-ESBL) = K. oxytoca (excluding ESBL producing strains)

Note: For ESBL, FEP is Cefepime, CTX is Cefotaxime, CAZ is Ceftazidime and CA is Clavulanic Acid. For ESBL positive

strains, the test interpretation should be reported as resistant for all penicillins, cephalosporins, and aztreonam.

NEG = Negative

POS = Positive

A negative ESBL test result does not rule out the presence of an ESBL masked by an AmpC beta-lactamase.

",! etc. = See performance characteristics identified by the drug code with this symbol in the Comment column in

Systems Product Information.

**Eco(+ETEC) = E. coli (including susceptible enterotoxigenic strains implicated in traveler's diarrhea)
