REFERENCE RANGE Meaning and
Definition
-
Reference range is a term used in medical and diagnostic settings to define the range of values considered normal for a particular test or measurement. It refers to the numerical values or range of values that represent the healthy or typical physiological levels for a specific measure in a population. Reference ranges are established through the analysis of a large number of healthy individuals and serve as a standard against which results from patient samples can be compared.
The reference range can vary depending on various factors, including age, gender, and physiological conditions. In some cases, reference ranges may also be specific to certain populations or ethnic groups. These ranges are typically determined based on statistical analysis of the test results obtained from a representative sample of a healthy population.
When a medical test or diagnostic measurement is performed, the results are compared to the reference range to determine whether the values fall within the normal range or if they deviate significantly. Results falling outside the reference range may indicate the presence of an abnormality or potential health issue that requires further investigation or medical intervention.
The reference range is an important tool in medical diagnostics and allows healthcare professionals to interpret test results and identify potential abnormalities or deviations from normal physiological function. It provides crucial information for accurate diagnosis and effective treatment planning.
