Calibration Observation

Calibration BG value observation profile is used to record the BG data related to the CGM sensor, to verify the device is working as expected with the BG value calculated. The goal of calibration is to minimise any measurement uncertainty by ensuring the accuracy of test equipment.

Example

NOTE to developer: This is only a sample resource. For the resource structure and valusets always refer the section "Overview" under each profile definition in the Implementation guide. If an element is defined as an array (0..*) in the standard and in RDC profile as an object (0..1), please note that it should still carry the structure of an array with one occurance. The structure for all resources as per the FHIR standard can be found at https://www.hl7.org/fhir/STU3/resourcelist.html
