About Laboratory Data

The laboratory domain covers diagnostic testing data including test orders, specimens, results, and reference ranges. LOINC codes provide standardized identifiers for laboratory observations and are essential for normalizing lab results across different EHR and LIS systems.

Healthcare data teams build lab data pipelines for clinical decision support, population health screening, and quality measure reporting. Key integrations include HL7 FHIR Observation resources for interoperability, HL7 ORU messages for result delivery, and SNOMED CT for interpretation coding.

810 laboratory terms

Basic Metabolic PanelBMP

A standard laboratory panel measuring key blood chemistry values including glucose, calcium, sodium, potassium, bicarbonate, creatinine, and blood urea nitrogen. BMP results are documented in EHR laboratory systems using LOINC codes and used in inpatient monitoring, ED assessment, and chronic disease management.

Complete Blood CountCBC

A standard laboratory panel measuring the cellular components of blood including red blood cells, white blood cells, hemoglobin, hematocrit, and platelets. CBC results are documented in EHR laboratory systems using LOINC codes and used in routine health screening, anemia workup, and infection monitoring.

Comprehensive Metabolic PanelCMP

A standardized laboratory test panel captured in EHR and claims systems using LOINC codes, measuring 14 blood chemistry values including glucose, electrolytes, kidney, and liver function. CMP results inform chronic disease management workflows in clinical data warehouses.

HematologyHEM

A clinical specialty and laboratory discipline focused on disorders of the blood and blood-forming organs, including anemia, clotting disorders, and leukemia. In healthcare data systems, hematology encompasses lab result domains such as CBC panels, coagulation studies, and bone marrow reports, which are stored in EHR and LIS platforms and exchanged via HL7 interfaces.

PathologyPATH

A clinical discipline and data domain encompassing the examination of tissue, cell, and bodily fluid specimens to diagnose disease. In healthcare data systems including LIS, EHR, and claims platforms, pathology data includes surgical pathology, cytology, and autopsy records coded using CPT, SNOMED, and ICD systems, requiring specialized data engineering pipelines to manage unstructured report text alongside structured result fields.

Specimen Sourcespec_src_cd

Coded representation of the anatomical origin or material type of a biological specimen, such as blood, urine, or CSF, stored as a standardized code in LIS and EHR systems. Data engineers use this field for specimen classification, test panel validation, result routing logic, and cross-system laboratory data harmonization pipelines.

Speech Language PathologistSLP

A licensed clinician specializing in communication and swallowing disorders, identified by provider type codes in EHR, claims, and credentialing systems. Data engineers use SLP taxonomy codes (e.g., NUCC 235Z00000X) to filter therapy claims, validate provider credentials, and support care coordination analytics across rehabilitation datasets.

culture active indicatorcult_actv_ind

Binary flag indicating whether a microbiology culture test is currently active within the laboratory information system. Used to filter active versus inactive culture orders in clinical workflows, quality reporting, and lab result tracking across inpatient and outpatient settings.

culture active statuscult_actv_sts

Categorical status value representing the current activity state of a microbiology culture test, such as pending, in-progress, resulted, or cancelled. Supports laboratory workflow management and enables downstream clinical decision-making based on specimen processing stage.

culture addresscult_addr

Physical or facility location string associated with a microbiology culture test order or result record in EHR and laboratory information systems. Identifies where the specimen was collected, processed, or reported, supporting chain-of-custody tracking, public health reporting integrations, and downstream analytics on infection site distributions across clinical data warehouses.

culture adjustment amountcult_adj_amt

Monetary value representing a financial adjustment applied to a microbiology culture test charge, such as a contractual write-off, payer discount, or billing correction. Used in revenue cycle management to reconcile billed charges against actual reimbursement on lab claims.

culture agecult_age

The elapsed time, typically in hours or days, since a microbiology culture specimen was initiated or inoculated. Used in laboratory workflows to monitor incubation duration, flag overdue results, and ensure timely reporting of pathogen growth within clinical turnaround standards.

culture allowed amountcult_alwd_amt

The maximum dollar amount a payer will reimburse for a microbiology culture test based on the contracted fee schedule or benefit plan. Used in claims adjudication and revenue cycle reporting to determine payer liability and calculate patient cost-sharing obligations.

culture amountcult_amt

Monetary value field representing the charge, reimbursement, or cost associated with a microbiology culture test within laboratory billing, claims, and EHR systems. Used in revenue cycle management platforms to capture CPT-coded lab service fees, reconcile payer remittance amounts, and support downstream financial analytics for clinical laboratory operations.

culture approval statuscult_appr_sts

The authorization state of a microbiology culture test order, indicating whether the test has been approved, denied, or is pending review. Used in prior authorization workflows and utilization management to ensure payer or clinical approval before specimen processing begins.

culture approved bycult_appr_by

Identifier or name of the clinician, supervisor, or system user who authorized a microbiology culture test order or result. Used in laboratory audit trails to maintain chain-of-custody documentation and support regulatory compliance with result verification requirements.

culture arrival timecult_arrv_tm

The timestamp recording when a microbiology culture specimen physically arrived at the laboratory for processing. Used to calculate specimen turnaround time, monitor pre-analytical delays, and ensure compliance with lab accreditation standards for timely specimen handling.

culture arrived datecult_arrv_dt

The calendar date on which a microbiology culture specimen was received at the processing laboratory. Used in laboratory information systems to establish the start of the testing timeline, support quality metrics, and document chain-of-custody for specimen integrity verification.

culture assessmentcult_asmt

The clinician's or microbiologist's narrative or structured evaluation of a microbiology culture result, including interpretation of organism growth, sensitivity patterns, and clinical significance. Used to guide treatment decisions and communicate findings within the patient's clinical record.

culture balancecult_bal

Outstanding financial amount remaining on a microbiology culture test account after payments, adjustments, or insurance remittance have been applied within laboratory billing and revenue cycle systems. Tracked in EHR and claims platforms to manage patient receivables, trigger collections workflows, and support accounts receivable aging reports for clinical laboratory services.
