This page is for general educational purposes only. It is not medical advice, and it is not a substitute for consultation with a qualified healthcare professional. Laboratory results should always be interpreted by a licensed clinician who knows your health history. Laboratory tests of this kind are used for screening and monitoring, not for diagnosis on their own — a diagnosis can only be made by a licensed clinician who evaluates results in the context of your health history and examination. If you have questions about your health or your results, talk with your doctor. If you think you may be experiencing a medical emergency, call 911.
