C-DAC's Toolkit for LOINC (CLNtk)

C-DAC's Toolkit for LOINC is a specially designed FOSS toolkit for easy access and integration of LOINC standards in healthcare applications. Logical Observation Identifiers Names and Codes (LOINC®) is an international standard for identifying health measurements, observations, and documents.
The toolkit provides simple-to-use APIs for LOINC integration. It enables clinicians and researchers to find relevant LOINC codes from its components including, long common name, short name, display names, and other related information.
The toolkit enables clinicians and researchers to find relevant LOINC codes from its components including, the long common name, short name, display name, and other related information.
LOINC has two main parts: laboratory LOINC and clinical LOINC.
LOINC is a database and universal standard for identifying clinical information in electronic reports. It provides a set of universal names and identifier codes for identifying laboratory and clinical test results.
Regenstrief LOINC Mapping Assistant (RELMA) is a Windows-based mapping utility for searching the LOINC database and mapping local codes to LOINC codes. It is available for free.
