Normal ranges for lab blood works tool
Published: 7 Apr 2024
Definition of Reference Range
The typical definition of a reference range (often implicitly assumed) derives from the most frequently observed values within a representative population sample.
Optimal Levels
For many substances, optimal levels typically align with the values most commonly found in the population. These levels closely correspond to the central tendencies (e.g., mean) of those observed in the population. Physicians and healthcare professionals use these reference ranges as a basis for interpreting patient test results.
Reference Ranges vs. Optimal Ranges
Reference ranges generally represent the usual (or normal) values found in approximately 95% of the population. In contrast, optimal (health) ranges or therapeutic targets are based on concentrations or levels associated with optimal health or minimal risk of complications and diseases. These may also be referred to as standard ranges.
Optimal Health Ranges
Optimal health ranges describe the values associated with the most beneficial health outcomes.
Medical Tests Analyzer
Medical Tests Analyzer provides default reference ranges and measurement units for each laboratory test procedure with quantitative results. Users can customize these intervals for different ages and genders. Laboratories may also use varying measurement units. The tool allows users to adjust reference ranges and units and store them for future use.
Measurement Units and Reference Ranges
Certain lab test parameters (e.g., Calcium, Sodium, Potassium) can be measured in mmol/L (or mEq/L) or mg/dl. Laboratories may choose to weight measurements in pounds or kilograms. Regardless of the units used, results are interpreted relative to the reference ranges provided by the laboratory. Medical Tests Analyzer allows users to modify measurement units and reference ranges.
Variability in Units and Ranges
The units of measurement and reference ranges used by laboratories can vary. Therefore, users may encounter differing values from those recorded by Medical Tests Analyzer. The tool allows users to update the naming and reference ranges of measurement units.
