Test Identifier
Full test name plus unique code (LOINC or internal laboratory code) so systems and staff reference the same assay unambiguously.
Clear reference ranges reduce diagnostic ambiguity, support consistent clinical decisions, and simplify data exchange between labs and EHRs. A maintained document reduces repeat testing, supports accreditation audits, and helps meet privacy and recordkeeping obligations when patient data are included.
Key professionals use Reference Ranges Documents to interpret results, maintain quality, and manage clinical workflows.
Collaboration among these groups ensures ranges are clinically valid, method-specific, and integrated into patient records.
Full test name plus unique code (LOINC or internal laboratory code) so systems and staff reference the same assay unambiguously.
Lower and upper limits expressed numerically with units, including separate intervals for age, sex, pregnancy status, or other stratifications when relevant.
Specify measurement units explicitly (e.g., mg/dL, IU/L) and state conversion factors when multiple units are in use to prevent misinterpretation.
Describe the population used to derive the interval (sample size, demographics, inclusion/exclusion criteria, and clinical context).
Document the assay method, instrument model, reagents, and any calibration or traceability information that affects the interval.
Record version, effective date, authorizing signatory, and rationale for changes to support audits and clinical traceability.
