Describes how the lab report is used for a standard Lipid Profile - Cholesterol, Triglyceride and Cholesterol fractions. Uses LOINC codes

This profile was published on Sat, Feb 21, 2015 00:00+0000 as a draft by Health Level Seven, Inc. - FHIR WG.

Description of Profiles, Differentials, Snapshots, and how the XML and JSON presentations work.

This structure is derived from Observation.
