The physical street address of the facility or laboratory where a LOINC-coded observation or diagnostic test is performed. Used in clinical data management to associate test results with performing locations for reporting, accreditation, and audit trail purposes.
The concentration or potency value associated with a LOINC-coded observation, particularly relevant in pharmacy or toxicology panels where drug strength is a measured or reported attribute. Supports accurate interpretation of laboratory results tied to medication-related analytes.
A partial aggregated count or sum of LOINC-coded observations within a defined subset or grouping, such as a panel or category. Used in clinical data warehouse reporting to summarize diagnostic activity before computing final totals across broader observation sets.
The date of a surgical procedure associated with a LOINC-coded clinical observation or perioperative diagnostic test. Used in clinical documentation to link pre- or post-operative laboratory and diagnostic results to the corresponding operative event in patient records.
A system-generated unique identifier assigned to a LOINC-coded observation record within a clinical or laboratory information system. Enables consistent tracking, deduplication, and cross-system referencing of observation codes in EHR, LIS, and health data exchange environments.
The intended anatomical site, specimen type, or clinical system that a LOINC-coded observation is designed to measure or assess. Used in laboratory and diagnostic systems to specify what the test or observation is evaluating, such as serum, urine, or a specific organ system.
A classification code used to categorize a LOINC-coded observation within a structured clinical taxonomy, such as by discipline, method, or system. Supports hierarchical organization of diagnostic and laboratory codes for interoperability, reporting, and clinical decision support systems.
The numeric body or environmental temperature value captured as a LOINC-coded vital sign observation. Expressed in Celsius or Fahrenheit and used in clinical documentation systems to record patient temperature readings associated with specific LOINC codes for vital sign reporting.
The date on which a LOINC-coded observation or test code is retired, deprecated, or removed from active use within a clinical system. Used to enforce code validity windows, prevent use of outdated codes in new orders, and maintain accurate historical records in clinical data systems.
The time of day recorded in association with a LOINC-coded clinical observation or laboratory result. Used in diagnostic and clinical data systems to timestamp when a specimen was collected, a test was ordered, or a result was recorded, supporting accurate chronological event tracking.
The combined date and time value marking when a LOINC-coded observation was created, collected, resulted, or transmitted within a clinical information system. Provides a precise temporal reference for laboratory results, vital signs, and diagnostic findings in EHR audit and reporting workflows.
The formal long name or display title assigned to a LOINC code as defined by the Regenstrief Institute. Describes the full clinical meaning of the observation in standardized terminology, used for display in clinical interfaces, laboratory reports, and health information exchange documents.
The aggregate sum of LOINC-coded observations, results, or occurrences within a defined reporting period or data set. Used in clinical data warehouse and population health reporting to quantify the volume of diagnostic activity associated with specific LOINC codes or observation categories.
The complete count of distinct or cumulative LOINC-coded observation instances recorded within a dataset, facility, or reporting period. Used in quality measurement, laboratory utilization analytics, and clinical reporting to assess the frequency of specific diagnostic tests or observations.
The classification category of a LOINC-coded observation, such as laboratory, clinical, survey, or attachment. Distinguishes the nature of the observation within the LOINC hierarchy, enabling appropriate routing, display, and processing of results across clinical and administrative health data systems.
The standard unit of measure associated with a LOINC-coded observation result, such as mg/dL, mmHg, or beats per minute. Defined by the UCUM standard and used in laboratory and clinical systems to ensure consistent interpretation and comparison of quantitative diagnostic result values.
The date a LOINC observation code record was last modified in the clinical data system. Tracks when the standardized laboratory or clinical observation identifier was revised, ensuring downstream systems reference current LOINC terminology for accurate test result mapping and interoperability.
Indicates the clinical priority level assigned to a LOINC-coded observation or test order, such as routine, urgent, or STAT. Used in laboratory and clinical workflow systems to determine processing priority and turnaround time expectations for diagnostic results reporting.
The actual measured or observed result associated with a specific LOINC-coded clinical observation, such as a numeric lab result, a coded finding, or a text response. Paired with the LOINC code to provide a complete, standardized clinical data point for patient records and interoperability exchanges.
Identifies the specific release version of the LOINC standard under which a clinical observation code was assigned or validated. Ensures accurate interpretation of observation codes across systems, as LOINC terminology evolves with each release published by the Regenstrief Institute.
