Terminology - Classify Observation
POST /terminology/v1/classify/observation
Classifies an observation, including lab observations and panels, radiology or other reports. The input must be from one of the following code systems:
- LOINC
- SNOMED
Observations are classified using LOINC. For best results, provide the most specific LOINC coding for the observation. Rosetta classify operations may not return values for data using other code systems.
See the Classify API Overview for general principles that apply to all Classify API operations.

Display string.
Response Fields
The analyte or attribute being measured or observed (e.g., Sodium, Body weight, Discharge summary note) from LOINC Component.
From LOINC Class (e.g., CARD-US for cardiac ultrasound, RAD for radiology, HEM/BC for hematology/blood chemistry).
From LOINC System (e.g., Bld for blood, Liver).
From LOINC MethodType (e.g., IA for immunoassay, Visual for visual count).
From LOINC TimeAspect (e.g., Pt for point in time, 24H for 24 hours).
One of: antigen, antibody, immunoglobulin. Based on proprietary value sets developed from WHO, CDC, SNOMED, LOINC, and AMA coding advisories.
One of: activity, exam, imaging, laboratory, procedure, social-history, survey, therapy, vital-signs (Based on FHIR Observation Category)
