Reference Ranges


Reference or "normal' values are dependent on many factors, including patient age, gender, sample population and test method, and numeric test results can have different meanings in different laboratories.

For these reasons, you will not find reference ranges for all of the tests described on this web site. The laboratory report containing your test results should include the specific reference range for your test(s). Please consult your doctor or the laboratory that performed the test(s) to obtain the reference range if you do not have the laboratory report or cannot find it on our site.

For more information on reference ranges, please read Reference ranges and what they mean.
