Component.code coding for all possible sample types

This section describes how each sub component type has to be handled in Modelling. The following coding section needs to be updated based on the sub component type.

For example:

"component": [ // sub category - type
			{
		"code": {
			"coding": [ 
				{
					"system": "http://snomed.info/sct",
					"code": "769560003",
					"display": "With lunch (qualifier value)"
				}
			]
		}
	}
 ]

Below are some of possible codes for BG subType (component),for exhaustive list of codes refer HERE
