Reference 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 labs.
For these reasons, you will not find reference ranges for the majority of tests described on this web site. The lab report containing your test results should include the specific reference range for your test(s). To see a sample lab report, click
here. Please consult your doctor or the lab that performed the test(s) to obtain the reference range if you do not have the lab report.
If you have a question about the tests performed or your test results, you can submit a question using the
Ask Us form. It will be answered by a laboratory scientist.
