LOINC is a standardized code for lab tests, clinical measurements and observations. LOINC database includes: 1) observations reported by clinical laboratories; 2) results of therapeutic drug monitoring; 3) toxicology study of toxic compounds' built-in responses to the administration of therapeutic drugs; 4) serology – study of blood serum; 5) hematology – study of blood-related diseases affecting production and regulation of various components of blood such as blood cells, hemoglobin, blood proteins, bone marrow, platelets and mechanism of coagulations; 6) blood bank study; 7) microbiology, including lab results involving pathogens – disease causing bacteria; 8) cytology – study of cell structure and function including cell culture studies helpful for screening tests related to cancer cell detection using various body-fluids and brush tissues such as a pap-smear; 9) surgical pathology – study of the tissues removed using surgery and 10) fertility studies such as sperm count, ovulation tests, checking of hormone levels. The results include nontest level measurements such as menstrual cycles, drug doses and units of concentrations.

A retrospective cohort study was conducted among US Veterans with HK using ‘real-world’ data from the Veterans Affairs (VA) Corporate Data Warehouse (VA-CDW). This data source includes data from inpatient and outpatient encounters as well as pharmacy dispensing data, laboratory data (including test results), and other data available in the VA electronic health record. The medication data used in this study originated from outpatient pharmacy dispensings (identified using VA Drug Class Codes). The Logical Observation Identifiers Names and Codes (LOINC) universal standard for identifying medical laboratory observations was used. Extensive laboratory data quality and cleaning were conducted to ensure correct specimen classification and validate LOINC mapping. The following LOINCs were used to classify K+ tests and results: 2823–3, 77142–8, 75940–7, and 6298–4.

LOINC® is a terminology standard that supports the coding and capturing of laboratory test results, and other clinical observations. LOINC® uses universal identifiers enabling consistent interpretation across health care organizations. LOINC® is a set of unique identifiers that capture parameters that can be tested or quantified, such as represent laboratory tests, questions on a form, and clinical measurements. Clinical measurements are tests, observations, or measurement of a patient that do not involve taking a specimen. It was devised, is maintained, and is freely distributed by the Regenstrief Institute at the University of Indiana. The current version released in February 2017, has 83,377 codes with 46,621 users in 166 countries. It continues to expand internationally, as approximately 600 new users are added per month [7]. The purpose of this project was to determine the extent to which the 169 ACM elements are congruent with the globally recognized terminologies SNOMED CT® and LOINC®. We hypothesized that the proportion of elements with full or partial matches would be approximately 50%.
