What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

When is it used?

Used in lab systems, EHRs, and clinical data exchange.
May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
Status: ACTIVE
Order vs observation: Observation

What it does not mean

The code identifies the observation or test, not the actual result.

Key facts

Staphylococcus aureus glycopeptide resistant identified [Type] in Isolate

Staphylococcus aureus.glycopeptide resistant identified

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 [LOINC85045-3] 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.
