LOINC system

To describe test results properly, it is important that ah necessary information be included in the test description. Systems developed for expressing the results produced by the clinical laboratory include the Logical Observation Identifier Names and Codes (LOINC) system and the International Federation of Clinical Chemistry/International Union of Pure and Applied Chemistry (IFCC)/IUPAC system.

The LOINC system is a universal coding system for reporting laboratory and other clinical observations to fachitate... [Pg.9]

The meaning of each code is specified using a six-part name. The six parts are component (what is measured), kind of property (e.g., concentration versus titer), time aspect (single point in time versus timed collection), system (specimen) type, type of scale (e.g., quantitative, ordinal, and nominal), and method. For example, the LOINC name for a... [Pg.480]

In addition, SNOMED and LOINC are linked through a SNOMED code for each of the LOINC name parts, as illustrated in Figure 18-4. The SNOMED hierarchies for these codes wiE enable software systems to automatically compute that a complement fixation test for Rickettsia is a subtype of... [Pg.480]
