We want you to be informed, but we can not pretend to take the place of communication with your doctor or healthcare professional. The doctor should therefore apply the reference range supplied by the laboratory which performed the test rather than that used by another laboratory or one given in a book.Ģ. That means they have to establish their own ranges, and will provide your test result with an accompanying reference range appropriate to the laboratory.

Indeed for tests such as cholesterol the idea of a normal range has been replaced to a large extent by use of target values, achieved either by lifestyle changes or active treatment. When you examine test results from different populations, you quickly discover that what is "normal" for one group is not necessarily normal for another group. This is why the term "reference range" is preferred over "normal range". In other words, even in a "normal" population, a test result will lie outside the reference range in 5% of cases (1 in 20). In this way, ranges quoted by labs will represent the values found in 95% of individuals in the chosen ‘reference’ group. The reference range is then derived mathematically by taking the average value for the group and allowing for natural variation around that value (plus or minus 2 standard deviations from the average). A large number of individuals from a group who are thought to represent a "normal" population, will be tested for a particular laboratory test. The first step in determining a reference range is to define the population to which the range will apply. The interpretation of any clinical laboratory test involves comparing the patient's results with the test's "reference range".
