This ValueSet is part of the Health Device Data Transfer specification (HDDT) which defines profiles, operations, and value sets for sharing data between medical aids and digital health applications (DiGA). Core of the HDDT specification are Mandatory Interoperable Values (MIVs). MIVs are classes of measurements that contribute to defined use cases and purposes of DiGA.

The ValueSet HddtMivBloodGlucoseMeasurement defines the Mandatory Interoperable Value (MIV) "Blood Glucose Measurement". 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 Blood Glucose Measurement covers values from "bloody measurements" e.g. using capillary blood from the finger tip. Measurements are performed based on a care plan (e.g. measuring blood sugar before each meal) or ad hoc (e.g. a patient feeling dim what may be an indicator for a hypoglycamia). DiGA use cases served by this MIV require glucose values that are very acurate and therefore suited for therapeutical decision making.

The ValueSet for the MIV Blood Glucose Measurement contains LOINC codes for blood glucose measurements using blood or plasma as reference methods with the values provided as mass/volume and moles/volume. In addition more granular LOINC codes for "Glucose in Capillary blood by Glucometer" provided as mass/volume and moles/volume are included with the value set because these codes are already in use by several manufacturers of glucometers.
