| - | ==== Domains and Concept Classes ==== | + | |
| - | LOINC Concepts are located in such domains as “Observation”, | + | |
| - | + | ||
| - | Previously all concepts with a LOINC property of “**classtype**” with values “**1**” and “**2**” were considered to be Measurements. However, an initial analysis of such extended LOINC properties as “**property**”, | + | |

| - | ==== Relationships ==== | + | |
| - | Relationships are defined within LOINC and between LOINC and CPT, and LOINC and SNOMED: | + | |
| - | + | ||
| - | ===1. Internal LOINC relationships === | + | |
| - | A purpose of Internal LOINC relationships is to build a LOINC Hierarchy, which makes it easier to sort and browse the database. | + | |
