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 Mycobacterium tuberculosis gyrA gene fluoroquinolone resistance mutation. It is commonly used with the system or sample type Isolate/Specimen.

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: Molgen

What it does not mean

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

Key facts

Mycobacterium tuberculosis gyrA gene fluoroquinolone resistance mutation [Presence] by Molecular method
Mycobacterium tuberculosis gyrA gene fluoroquinolone resistance mutation
Test is to detect resistance of Mycobacterium tuberculosis strains to fluoroquinolones (FLQs) due to mutations present in the gyrA gene (coding for DNA gyrase). The types of mutations present or absent indicate if the isolate is susceptible or resistant to fluoroquinolones. This code is based on, but not limited in use to, the submitter's test kitHAIN Lifescience's GenoType MTBDRsl.
