Final answer:
The semantic tag is one of the parts of the LOINC fully specified name, along with the sample type, test location, and sample size.
Step-by-step explanation:
One of the parts of the LOINC fully specified name is the semantic tag. The semantic tag is a six-character code that provides information about the type of measurement being made.
For example, the semantic tag 'LP173421-1' indicates that the measurement is a quantitative result, while 'LP29684-5' indicates that the measurement is a qualitative result.
Other parts of the LOINC fully specified name include the sample type, test location, and sample size.
