Laboratory

The standardized classification code that categorizes a laboratory or diagnostic panel by clinical specialty or discipline, such as hematology or microbiology. Used in lab information systems and claims processing to route, bill, and report panel results accurately.

Records the required storage or processing temperature for a laboratory test panel, such as refrigerated or room temperature. Critical for specimen integrity, this value guides lab staff on handling conditions to ensure accurate diagnostic results and regulatory compliance.

The date on which a laboratory or diagnostic test panel is officially retired, deactivated, or removed from the active test catalog. Used in lab information systems to manage panel lifecycle, prevent ordering of discontinued tests, and maintain historical records.

Records the specific time of day associated with a diagnostic test panel event, such as collection or resulted time, in LIS and EHR systems. Used by data engineers to calculate turnaround time metrics, enforce time-sensitive panel ordering rules, and support chronological result sequencing.

Captures the full date and time value marking a key event in a diagnostic test panel's lifecycle, such as order creation, specimen collection, or result verification, in LIS and EHR systems. Data engineers use this field for audit trails, SLA reporting, and temporal joins across lab data pipelines.

The official descriptive name assigned to a group of related laboratory or diagnostic tests ordered together, such as Basic Metabolic Panel or Lipid Panel. Used in clinical ordering systems, lab reports, and patient-facing documentation to identify the test grouping.

Represents the aggregate sum of individual test components or associated charges within a diagnostic test panel in LIS, EHR, and claims systems. Data engineers use this field for billing reconciliation, utilization reporting, and validating that all expected panel components have been received and processed.

The total number of individual tests or components included within a specific laboratory or diagnostic panel. Used in lab information systems and billing workflows to verify panel completeness, calculate processing workload, and validate claims submissions.

Classifies a diagnostic test panel into a defined category such as metabolic, hematology, lipid, or prenatal in LIS and EHR systems. Data engineers use this field to partition lab data, apply type-specific validation rules, and map panels to CPT or LOINC code groupings in analytics pipelines.

The most recent date on which a laboratory or diagnostic panel definition, composition, or associated metadata was modified in the system. Used for audit tracking, version control, and ensuring clinical staff reference current panel configurations during test ordering.

Indicates the clinical priority level assigned to a laboratory or diagnostic panel order, such as routine, urgent, or STAT. Drives specimen processing prioritization and turnaround time expectations within the lab, directly impacting patient care decisions and clinical workflows.

Stores the discrete measured or calculated data point for a specific component within a diagnostic test panel in LIS and EHR systems. Data engineers rely on this field for result normalization, reference range comparisons, and populating structured clinical analytics datasets from HL7 OBX segments.

A numeric or alphanumeric identifier tracking the iteration of a laboratory or diagnostic panel definition, capturing changes to included tests, reference ranges, or clinical protocols over time. Ensures historical results are interpreted against the correct panel specification.

The postal zip code associated with the laboratory facility or collection site where a diagnostic panel is performed or processed. Used in lab management systems to support geographic reporting, network analysis, and routing of specimens to appropriate testing locations.

A measurement of the partial pressure of dissolved carbon dioxide in arterial blood, expressed in mmHg, used to assess ventilatory adequacy and the respiratory component of acid-base balance. PaCO2 above 45 mmHg indicates hypercapnia and respiratory acidosis from hypoventilation, while below 35 mmHg indicates respiratory alkalosis from hyperventilation. PaCO2 is the primary target for mechanical ventilator adjustments in respiratory failure management.

A measurement of the partial pressure of dissolved oxygen in arterial blood, expressed in mmHg, used to assess oxygenation status in critically ill patients. PaO2 below 80 mmHg indicates hypoxemia with values below 60 mmHg meeting criteria for supplemental oxygen therapy. The PaO2/FiO2 ratio is the primary oxygenation metric in ARDS severity classification with values below 300, 200, and 100 mmHg defining mild, moderate, and severe ARDS.

A laboratory measurement of the time in seconds for blood plasma to clot via the intrinsic coagulation pathway, used to monitor unfractionated heparin anticoagulation therapy and screen for coagulation factor deficiencies including hemophilia A and hemophilia B. PTT monitoring is required during intravenous heparin infusion therapy, with therapeutic targets typically 60-100 seconds depending on institutional protocol and indication.

A binary flag indicating whether a pathologist is currently active and eligible to sign laboratory reports, interpret specimens, or be assigned cases within the health system. Used in credentialing and lab information systems to control result authorization and workflow routing.

Describes the current operational status of a pathologist within the health system, such as active, inactive, or on leave. Used in laboratory management and credentialing systems to determine eligibility for case assignment, result sign-out, and participation in diagnostic workflows.

The physical or mailing address of a pathologist, including street, city, state, and zip code. Used in laboratory credentialing systems, provider directories, and correspondence workflows to support communication, licensing verification, and network participation documentation.
