LOINC Code 76346-6: Microorganism identified MS.MALDI-TOF Nom (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 Microorganism. 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: MS.MALDI-TOF

What it does not mean

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

Key facts

• Microorganism identified in Isolate by MS.MALDI-TOF
• Microorganism
• Microorganism identification by MALDI-TOF (matrix-assisted laser desorption ionization time of flight) is a diagnostic test for identifying the specific microorganism(s), i.e., bacteria and/or fungi, responsible for an infection. MALDI-TOF is a form of mass spectrometry that analyzes the proteins contained in an isolated colony. The resulting mass spectrum is compared to a reference database of bacterial and fungal protein mass spectra in order to identify the organism(s) present in the test sample. This term was created for, but is not limited in use to, bioMerieux's VITEK MS system, which is indicated for use to aid in the diagnosis of bacterial and fungal infections.
