LOINC display name : S. aureus glycopeptide resistant identified Nom (Isol);
LOINC long common name : Staphylococcus aureus glycopeptide resistant identified [Type] in Isolate;
LOINC short name : SA glyco resist Islt;
LOINC description : This term is used to report the presence of Staph aureus strains with intermediate
or heterogeneous glycopeptide resistance, called GISA and hGISA respectively. One
method for differentiating GISA from hGISA is based on comparison of inhibitory concentration
results for vancomycin plus teicoplanin [LOINC: 85045-3] with the result for vancomycin
alone [LOINC: 7059-9]. This term was created for, but is not limited in use to, bioMerieux's
ETEST GRD assay, which, when used together with a vancomycin susceptibility gradient
strip, can differentiate between GISA and hGISA.;
