Getting this type of testing regularly is the low hanging fruit when it comes to understanding your health, and can be the first step in many other areas of wellness.Now that you know more about SMRTX, let's talk about the importance of getting blood test analysis done. In this day and age, with many different health issues and chronic diseases being diagnosed and managed based on blood test results, it is crucial to get annual blood tests.

In this way, ranges quoted by labs will represent the values found in 95% of individuals in the chosen 'reference' group. This is why the term 'reference range' is preferred over 'normal range'. 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. In other words, even in a 'normal' population, a test result will lie outside the reference range in 5% of cases (1 in 20). The first step in determining a reference range is to define the population to which the range will apply. 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. Whether or not your test result is within the laboratory reference range, the result must be considered within the context of your personal circumstances, and with the benefit of your doctor's knowledge of your past medical history, current medication and the results of any other investigations.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 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).
