Terminology: Reference Range vs. Normal Range
The term "reference range" is preferred over "normal range" because:
* Population Variations: Test results can vary significantly across different groups of people. What is considered "normal" for one population may not be for another.
* Advancements in Medicine: For tests like cholesterol, the concept of a "normal range" has largely been replaced by "target values" that can be achieved through lifestyle changes or treatment.
Interpretation of Test Results
The reference range for a test is determined by:
* Selecting a representative "reference" population.
* Calculating the average value for the population.
* Allowing for natural variability around the average (plus or minus 2 standard deviations).
This range represents the values found in 95% of individuals in the reference group. However, even in healthy populations, 5% of test results fall outside this range.
Individualized Interpretation
It's essential to interpret test results within your unique circumstances. Your doctor will consider your:
* Medical history
* Current medications
* Other relevant investigations
