The MicroScan® Dried Gram-Positive MIC/Combo Panel is used to determine quantitative and/or qualitative
antimicrobial agent susceptibility of colonies grown on solid media of rapidly growing aerobic and facultative anaerobic
gram-positive bacteria. After inoculation, panels are incubated for 16 – 20 hours at 35°C +/- 1°C in a non-CO2 incubator,
and read either visually or with MicroScan instrumentation, according to the Package Insert.
This particular submission is for the addition of the reformulated antimicrobial Vancomycin at concentrations of 0.25 to
64 μg/ml to the test panel.
The gram-positive organisms which may be used for Vancomycin susceptibility testing in this panel are:
Enterococci (e.g., Enterococcus faecalis)
Staphylococci, including Staphylococcus aureus and Staphylococcus epidermidis (including heterogeneous methicillin-
resistant strains)
Indications for use as stated in the FDA summary.
