You must use the range supplied by the laboratory that performed your test to evaluate whether your results are 'within normal limits'.
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. This may be due to differences in lab testing equipment, chemical reagents, and analysis techniques. 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.
In this same way, labs may choose to use different units of measurement for your test results. In Medical Tests Analyzer interface you can adjust measurement units naming and reference interval (range) as well. On the right hand of the parameter you can find a small button. Open your test by clicking 'Edit Test' button. He can decide to note your weight in pounds or in kilograms. Also reference intervals may vary from area to area. Test's reference ranges may differ from lab to lab due to equipment and methodology differences. Frequently, what is considered a normal result range in your area is not totally the same somewhere else. The units of measurement that labs use to report your results can vary from lab to lab. Regardless of the units that the lab uses, your results will be interpreted in relation to the reference ranges supplied by the laboratory. Select a parameter on your test you want to update, for example 'Rheumatoid factor'. Click on the button and 'Reference Ranges' interface will popup. It is similar to the way, for instance, your physician chooses to record your weight during an examination. By using the interface you will be able to update name of measurement units and the parameter's reference range.
