  <description
               value="This ValueSet defines the Mandatory Interoperable Value (MIV) \&quot;Continuous Glucose Measurement\&quot;. The definition is made up from
- this description which provides the semantics and defining characteristics of the MIV
- a set of LOINC codes that define MIV-compliant measurement classifications along the LOINC axes _component_, _system_, _scale_ and _method_ 

The MIV _Continuous Glucose Measurement_ covers values from continuous monitoring of the glucose level, e.g. 
by rtCGM in interstitial fluid (ISF). Measurements are performed through sensors with a sample rate of up to 
one value per minute. By this _Continuous Glucose Measurement_ can e.g. be used to assess dependencies between a 
patient's individual habits and behavious and his glucose level. Due to the high density of values over a long period 
of time, many key metrics can be calculated from _Continuous Glucose Measurement_ which help the patient and 
his doctor to easily capture the status of the patient's health and therapy.

The ValueSet for the MIV _Continuous Glucose Measurement_ includes codes relevant to continuous glucose 
monitoring (CGM) in interstitial fluid (ISF), considering mass/volume and moles/volume as commonly used units. 
In the future codes defining non-invasive glucose measuring methods may be added to this value set."/>
