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 is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Glucose measurements in range/Total glucose measurements. It is commonly used with the system or sample type Interstitial fluid.

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
Method: Calculated

What it does not mean

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

Key facts

Glucose measurements in range out of Total glucose measurements during reporting period

Glucose measurements in range/Total glucose measurements

The percentage of blood glucose levels that are in a target range for patients using continuous glucose monitoring (CGM) devices. The International Consensus in Time in Range (IC-TIR) defines the target range between 70 and 180 mg/dL (3.9-10.0 mmol/L).[PMID31177185] The goal is to reduce the time spent in hypoglycemia (glucose levels < 70 mg/dL).
