Concepts

This case-sensitive code system http://terminology.hl7.org/CodeSystem/v2-0257 defines the following codes in a Is-A hierarchy:

Code	Display	Definition	status
CFST	Fasting (no calorie intake) for the period specified in the time component of the term, e.g., 1H POST CFST	Fasting (no calorie intake) for the period specified in the time component of the term, e.g., 1H POST CFST	A
EXCZ	Exercise undertaken as challenge (can be quantified)	Exercise undertaken as challenge (can be quantified)	A
FFST	No fluid intake for the period specified in the time component of the term	No fluid intake for the period specified in the time component of the term	A
