Laboratory

The identifier or reference linking a derived or aliquot specimen to its originating parent specimen in LIS and EHR systems. Data engineers use this field to construct specimen lineage hierarchies, trace aliquot chains, and support parent-child relational models in lab data warehouse and analytics environments.

Represents a ratio or proportional value associated with a biological specimen in laboratory systems. Used in LIS and EHR platforms to express concentration, purity, or composition metrics such as percent saturation or cell differential percentages in diagnostic workflows.

Defines the time span associated with biological specimen collection or validity in LIS and EHR systems. Captures intervals such as 24-hour urine collection windows or timed blood draws, critical for accurate lab result interpretation and downstream claims adjudication in PBM and payer platforms.

Stores the telephone contact number associated with a biological specimen record, typically linked to the ordering provider, collecting facility, or patient in LIS and EHR systems. Used by data engineers to support result routing, specimen tracking inquiries, and audit trail compliance in laboratory workflows.

Indicates the urgency ranking assigned to a biological specimen in LIS and EHR systems, such as STAT, routine, or ASAP. Drives processing queues and turnaround time SLAs in laboratory workflows, and is critical for data engineers building real-time alerting pipelines and operational dashboards.

Records the measured volume, mass, or count of a biological specimen collected in LIS and EHR systems. Values may be expressed in mL, mg, or unit counts depending on specimen type. Critical for sufficiency validation logic, rejection workflows, and downstream lab result accuracy in clinical data pipelines.

Captures the minimum and maximum acceptable value limits for a biological specimen measurement in LIS and EHR systems. Used to define reference intervals for lab results, supporting data engineers in building result flagging logic, outlier detection, and clinical decision support alert pipelines.

Represents the unit price or reimbursement rate associated with processing a biological specimen in claims, LIS, and PBM systems. Used by data engineers in cost analysis, lab billing reconciliation, and fee schedule validation workflows across payer and provider data platforms.

Captures the clinical justification or explanation for specimen collection in LIS and EHR systems, often aligned with ICD diagnosis codes or provider-documented indications. Used by data engineers to support medical necessity validation, prior authorization workflows, and claims audit processes in payer platforms.

Stores an external identifier or pointer linking a biological specimen to related records across LIS, EHR, and claims systems, such as accession numbers, order IDs, or requisition references. Enables data engineers to perform cross-system joins, traceability mapping, and specimen lifecycle tracking in integration pipelines.

A code identifying the reason a specimen was rejected by the laboratory and not processed, such as hemolysis, lipemia, improper container, clotted sample, quantity not sufficient, mislabeled specimen, or temperature excursion during transport. Specimen rejection reason codes are tracked in laboratory quality metrics to identify pre-analytical error sources and calculate specimen rejection rates by collection unit, phlebotomist, and test type.

Contains the quantitative or qualitative outcome measurement produced from analyzing a biological specimen in LIS and EHR systems. Values may include numeric lab values, interpreted findings, or coded results mapped to LOINC or SNOMED. Central to clinical decision support, quality measure reporting, and claims adjudication pipelines.

Represents a calculated or derived rating assigned to a biological specimen or its result in LIS and EHR systems, such as a pathology grading score or risk stratification index. Used by data engineers in analytics pipelines supporting quality metrics, population health programs, and clinical outcome reporting.

Defines the ordinal position of a biological specimen within a series of collections or processing steps in LIS and EHR systems. Critical for timed specimen protocols such as glucose tolerance tests, enabling data engineers to correctly order records in result aggregation and longitudinal lab data pipelines.

Records the date on which a biological specimen was collected or processed as a laboratory service in LIS, EHR, and claims systems. Used by data engineers to align lab events with encounter timelines, validate claims date fields, and support episode-of-care grouping in payer and provider analytics platforms.

Indicates the clinical seriousness level associated with a biological specimen's findings or collection context in LIS and EHR systems, such as critical, abnormal, or normal severity designations. Used by data engineers to build result prioritization logic, critical value alerting workflows, and risk stratification models in clinical data platforms.

Identifies the anatomical origin or collection site of a biological sample (e.g., Blood, Urine, CSF, Wound, Throat) in LIS and EHR systems. Critical for lab result interpretation, data normalization, and linking orders to results in clinical data pipelines.

Captures the beginning date of a specimen collection period or protocol in LIS and EHR systems, particularly relevant for timed collections such as 24-hour urine or serial blood draws. Used by data engineers to calculate collection durations, validate temporal data integrity, and align lab records with encounter and claims timelines.

Represents the current processing or disposition state of a biological specimen in LIS and EHR systems, with values such as collected, received, in-process, resulted, or rejected. Critical for data engineers building specimen tracking pipelines, rejection rate analytics, and laboratory operational dashboards across provider and payer data environments.

Identifies the intended destination or reference endpoint for a biological specimen in LIS and EHR systems, such as a target laboratory, department, or result threshold. Used by data engineers to support specimen routing logic, result delivery workflows, and network lab integration pipelines across provider and health plan data systems.
