Clinical

Version or iteration number indicating how many times a laboratory record, result, or report has been updated or corrected. Used to track amendments to lab results, maintain data lineage in clinical systems, and ensure downstream consumers reference the most current and accurate lab information.

Indicates the clinical risk level associated with a laboratory test or its anticipated results, such as patient safety concerns, infectious hazard classifications, or critical value thresholds. Used in lab information systems to trigger appropriate handling protocols and clinician notifications.

Specifies the specimen collection or sample administration pathway for a laboratory test, such as venipuncture, capillary draw, urine catch, or swab. Critical for lab processing workflows to ensure correct collection procedures and accurate result interpretation.

Records the calendar date on which a laboratory test or specimen collection is planned to occur. Used in lab scheduling systems and EHRs to coordinate patient appointments, staffing, and equipment availability while supporting pre-authorization and care coordination workflows.

Records the clock time at which a laboratory test or specimen collection is planned to occur. Used alongside scheduled date in lab scheduling systems to manage patient flow, timed specimen requirements such as fasting labs, and coordination with clinical staff.

Calculated numeric or categorical rating derived from one or more laboratory measurements in EHR and clinical analytics systems. Used in risk stratification models, disease management programs, and quality reporting pipelines to assess patient acuity based on lab data patterns.

Numeric ordering position assigned to a laboratory test within a panel, order set, or batch submission in LIS and EHR systems. Supports proper ETL load ordering, result display sequencing, and downstream data pipeline processing in clinical data warehouses.

Calendar date on which a laboratory service was rendered, specimen collected, or test performed. Captured in EHR, LIS, and claims systems as a critical dimension for episode-of-care analysis, claims adjudication timelines, and HEDIS quality measure attribution logic.

Coded or categorical indicator reflecting the clinical seriousness of a laboratory finding, such as critical, abnormal, or panic values, in EHR and clinical decision support systems. Used in alerting workflows and risk stratification models to prioritize patient interventions.

Captures the patient's biological sex as recorded for a laboratory service, which directly influences reference ranges and result interpretation for many diagnostic tests including hormone panels, hematology, and metabolic panels. Ensures accurate clinical evaluation of lab findings.

Identifier indicating the originating system, facility, or entity that generated or transmitted a laboratory record, such as a reference lab, hospital LIS, or point-of-care device. Critical for data provenance tracking and deduplication logic in healthcare data integration pipelines.

Date marking the initiation of a laboratory test, specimen collection period, or multi-day lab protocol in EHR and LIS systems. Used in longitudinal analytics and episode construction to define the beginning boundary of lab-related clinical activity within data warehouse models.

Records the clock time at which a laboratory procedure or specimen collection process began. Used in lab information systems to calculate processing durations, support timed diagnostic protocols such as glucose tolerance tests, and maintain chain-of-custody documentation.

Captures the US state or territory associated with the laboratory facility performing the test or the patient's location at time of service. Used in regulatory reporting, licensure compliance tracking, and geographic analysis of lab service utilization patterns.

Current workflow state of a laboratory order or result, such as ordered, collected, in-process, resulted, or cancelled, in EHR and LIS systems. Used by data engineers to filter incomplete records during ETL processing and to monitor lab turnaround time in operational dashboards.

Records the physical street address of the laboratory facility where testing is performed. Used for facility credentialing, specimen transport logistics, regulatory compliance, and directing patients or couriers to the correct collection or testing location.

Captures the concentration or potency of a reagent, contrast agent, or preparation substance associated with a laboratory procedure. Relevant in toxicology, pharmacokinetic testing, and culture media preparation where substance concentration directly affects result validity.

Represents a partial financial sum for laboratory services before application of adjustments, taxes, or additional charges. Used in billing and revenue cycle systems to itemize lab service costs within a larger claim or encounter, supporting accurate reimbursement calculations.

Records the date of a surgical procedure associated with laboratory specimen collection, such as intraoperative tissue samples or surgical pathology. Links lab results to the corresponding operative encounter for continuity of clinical documentation and post-surgical care planning.

A unique system-generated key assigned to a laboratory record within a health information system. Used to consistently identify and cross-reference lab orders, results, and specimens across EHR platforms, lab information systems, and data warehouses without ambiguity.
