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 standard deviation. 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 standard deviation Calculated
Glucose standard deviation
Standard deviation (SD) is a metric used to monitor glycemic variability (GV) and evaluate glycemic control. It represents the spread in glucose readings around the average and can be calculated different ways that vary by timescales. SD may be calculated for total variability for multiple days, within a single day, for a specific time of day over a period of time, and between days of the week.[PMID29916742] A recommendation is for the SD to be less than one third of the mean glucose. For instance, a patient has a mean glucose of 180 mg/dl, then the target SD is 60 mg/dl (3.3 mmol/L) or less.
