LOINC, or Logical Observation Identifiers Names and Codes, is a standardized coding system used to identify health measurements, observations, and documents. It was developed to facilitate the exchange and aggregation of clinical data across different health systems, ensuring consistency and accuracy in reporting. The LOINC system includes codes for laboratory tests, clinical observations, and other health-related data. By using these standardized codes, healthcare providers can improve communication, enhance data sharing, and support better patient care through more reliable health information management.
