Reference values are dependent on many factors, including patient age, sex, 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 health care provider or the laboratory 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.
