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 Activity level. It is commonly used with the system or sample type ^Patient.

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

  • Activity level [Acceleration]
  • Activity level
  • Activity level is calculated as vector magnitude units (VMU) based on axial accelerations in all three dimensions and is reported in gravity (g) units. This term was created for, but is not limited in use to, the Zephyr BioHarness, a physiological monitoring belt device that captures and transmits multiple physiologic parameters.
