A reference range is a set of values that includes upper and lower limits of a lab test based on a group of otherwise healthy people. By comparing your test results with reference values, you and your health care provider can see if any of your test results fall outside the range of expected values and gain clues to help identify possible conditions or diseases.
Laboratory testing is performed in many different settings, from the large reference lab to your own home. As we learn to take a more active role in our medical care, a clear understanding of what happens when our blood or urine or other body fluid specimen is sent "off to the lab" will help us to become more knowledgeable participants in our own healthcare.
This form enables patients to ask specific questions about lab tests. Your questions will be answered by a laboratory scientist as part of a voluntary service provided by one of our partners, American Society for Clinical Laboratory Science. Please allow 2-3 business days for an email response from one of the volunteers on the Consumer Information Response Team.Send Us Your Question
