LOINC Code 85049-5: ESBL by cefotaxime to cefotaxime-clavulanate IC ratio ARD gradient strip Ql (Isol)

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Extended-spectrum beta lactamase by cefotaxime to cefotaxime+clavulanate inhibitory concentration ratio. It is commonly used with the system or sample type Isolate.

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: Both
• Method: Gradient strip ARD

What it does not mean

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

Key facts

• ESBL by cefotaxime to cefotaxime-clavulanate IC ratio [Presence] by ARD gradient strip
• Extended-spectrum beta lactamase by cefotaxime to cefotaxime+clavulanate inhibitory concentration ratio
• This term is used to report the presence or absence of extended spectrum beta-lactamase (ESBL) enzymes based on inhibitory concentrations of cefotaxime and cefotaxime+clavulanate. This term was created for, but is not limited in use to, bioMerieux's ETEST ESBL assay.
