LOINC Code 82262-7: Estimated activity metabolic rate/Standard RMR [Relative energy/Time]

82262-7 is a LOINC code used to identify Estimated activity metabolic rate/Standard RMR [Relative energy/Time] in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Activity metabolic rate/Standard resting metabolic rate. It is commonly used with the system or sample type ^Patient.

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 metabolic rate/Standard resting metabolic rate. 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: Both
  • Method: Estimated

What it does not mean

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

Key facts

Estimated activity metabolic rate/Standard RMR [Relative energy/Time]
Activity metabolic rate/Standard resting metabolic rate
The measured metabolic equivalent of task (MET) calculated based on estimated exercise metabolic rate and the standard resting metabolic rate (RMR). The standard RMR is defined as 3.5 mL O2/kg/min. The exercise metabolic rate can be measured [LOINC82261-9], estimated (this term) or reported [LOINC: 82263-5]. The reference source used for the estimated exercise metabolic rate should also be provided [LOINC: 82280-9]. Additionally, METs can be further adjusted based on patient demographics, such as age, sex and BMI [LOINC: 82271-8].
