Scope

The Standard Lab Titer Observation profile is intended to be used for labratory tests who’s values could be reported using a numerator and denominator, or in otherwords a ratio of a constituent to a whole volume. These results are numeric but do not typically have units of measure however, LOINC provides example units of measure of “{titer}”.

Observation.code

This element is constrained to LOINC codes that have example units of measure of “{titer}”.

Observaiton.value

This element is constrained to the Ratio data type.

Example

The following example is provided to illustrate conformant resource content to this profile
