What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

What it does not mean

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

Key facts

Measured RMR

Metabolic rate^resting

Resting metabolic rate (RMR), sometimes called resting energy expenditure (EE), is commonly measured by indirect calorimetry, which requires quantification of oxygen consumption and sometimes carbon dioxide production while a patient is resting. Indirect calorimetry techniques for measuring RMR are commonly used in research and clinical applications.[PMCIDPMC3928639] Results are used to determine minimal energy requirements for patients receiving nutritional therapy. RMR estimates are also used to counsel patients regarding caloric intake in weight loss programs.
