In some ways it seems surprising that there are not many functional medicine lab values charts online, but this may be due to the way that functional medicine is practiced. We are going to give you a functional medicine lab values chart further on in this article, so please keep reading.
As guiding principles, most functional medicine clinicians and teachers really value the uniqueness of the individual. Therefore, while it is useful to have a list of reference ranges that functional medicine doctors use, it is also important to understand that while these numbers are important and provide a guide, that we must treat the actual person, which is much, much more than numbers.
For example, some of the research we review in the hormone section of our functional medicine course at our functional medicine school shows that reference ranges for sex hormones vary to a much larger degree than normal functional medicine reference ranges indicate. Therefore, in utilizing the information in this functional medicine lab value chart, please remember that even these reference ranges, while more tuned into optimal levels than standard reference ranges, they are still just a guide.
