You must use the range supplied by the laboratory that performed your test to evaluate whether your results are 'within normal limits'.
The information provided in this article will help you understand:
Why so few reference ranges are provided in the test information on this site: the accuracy of laboratory testing has significantly evolved over the past few decades, but some lab-to-lab variability can occur. This may be due to differences in lab testing equipment, chemical reagents, and analysis techniques. Most people can now access their lab test results directly via the Internet, but very few lab reports have been designed to convey the meaning of those results in a way people who are not health professionals can understand or put in context.
Want to know some of the optimal ranges for blood chemistry figures? It's more complicated than the following list since the numbers change based on your age and weight and sex, but here's a good reference range to keep handy. Medical Tests Analyzer is the best software tool.Knowing something is 'off' will tell you what to look up on the internet, and knowing this you may be able to spot something the doctors miss. Reference ranges for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. A reference range is usually defined as the set of values 95 percent of the normal population falls within (that is, 95% prediction interval). It is determined by collecting data from vast numbers of laboratory tests.
