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

Sometimes, healthy people get results outside the reference range, while people with health problems can have results in the normal range. Reference ranges are based on the normal test results of a large group of healthy people. A reference range may also be called 'normal values.' You may see something like this on your results: 'normal: 77-99mg/dL' (milligrams per deciliter). If your results fall outside the reference range, or if you have symptoms despite a normal result, you will likely need more testing.
Your lab results may also include one of these terms:
Negative or normal, which means the disease or substance being tested was not found
Positive or abnormal, which means the disease or substance was found
Inconclusive or uncertain, which means there wasn't enough information in the results to diagnose or rule out a disease. Lab results are often shown as a set of numbers known as a reference range. If you get an inconclusive result, you will probably get more tests.
Tests that measure various organs and systems often give results as reference ranges, while tests that diagnose or rule out diseases often use the terms listed above.The range helps show what a typical normal result looks like.
But not everyone is typical.
