The 12 pages that link to Reference range, each with the reason it gives.

• BiomarkerRelated: Interpreting a biomarker often requires comparing its value with a suitable reference population.

• ThrombocytopeniaRelated: A platelet count is judged against a laboratory reference range, not an absolute universal boundary.

• HypokalemiaRelated: Clinical cutoffs for low potassium depend on the laboratory's reference interval.

• Thyroid function testsRelated: TSH and thyroid hormone results must be interpreted against assay-specific ranges and clinical context.

• Pulmonary function testingRelated: Test results are compared with predicted values that account for relevant characteristics.

• Gait analysisRelated: Normative gait values depend on population characteristics and testing protocols.

• Vital signsRelated: Vital-sign readings are interpreted against age- and context-appropriate ranges.

• Erythrocyte sedimentation rateRelated: ESR reference limits vary with age, sex, method, and laboratory, so one cutoff does not fit everyone.

• Medical testRelated: Many test results are judged against ranges rather than a simple positive-or-negative threshold.

• Blood testRelated: A result is interpreted against a reference range, not as a diagnosis by itself.

• Comprehensive metabolic panelRelated: A result outside the laboratory's range prompts context-specific interpretation rather than proving disease.

• Medical laboratoryRelated: A result is interpreted against an appropriate range, not as an isolated number.
