  • Using A Functional Model for Interpreting Standard Blood Tests

    The only thing certain about a blood test is that nothing is certain. With that said, there is a tremendous amount of data that can be extracted from a blood test, providing that one has an understanding of how to interpret it.

    Ultimately blood test results can help you identify the best nutritional course of action so that you can start feeling better immediately.

    One major problem with standard blood tests is that the conventional “healthy” reference ranges are often times not accurate. Laboratory “healthy and normal” reference-ranges are actually statistical averages that do not necessarily reflect ideal values. When using conventional reference-ranges, it is very easy to overlook critical data that could reveal information about your body’s health and the health challenges you may be experiencing.

    When correctly interpreted using a Functional Model blood tests can in fact reveal data that often times gets overlooked. For example, a typical, “normal”, “conventional” reference-range for BUN (Blood, Urea, Nitrogen) is anywhere between 7-25. This range is far from accurate. A person with a BUN level of 7 will have a variety of health issues. Someone with that low of a BUN level is extremely undernourished. A BUN level of 7 is also a strong indicator of several degenerative processes in action. Whereas a BUN level of 25 indicates kidney stress, dehydration, and possible electrolyte insufficiency. Neither 7 nor 25 are healthy values. And yet, neither may indicate a definitive diagnosis of pathology by conventional medical standards.

    One primary reason why certain lab values get overlooked is because most physicians are not trained to interpret laboratory tests from a Functional Model perspective. Doctors are trained instead to identify disease states, many of which have been in progress for a long period of time. This is the major difference between the pathological view of the body and a Functional Model view of the body.

    A Functional Model interpretation of the body is a holistic model, which involves taking into account that:

    1. A person is biochemically unique.
    2. The body functions through a highly complex network, involvingnumerous systems.
    3. A person is a holistic being, comprised of an integrated networkinvolving body, mind, and spirit.

    From this Functional perspective, individual blood chemistry factors are then taken into account along with other blood chemistry factors. Isolating ONLY glucose, without considering other, important glucose metabolism factors such as INSULIN and HEMOGLOBIN A1C for example, falls short of understanding what is really taking place for the individual.

    Using a Functional Model Perspective, a blood test can potentially yield a great amount of information, which ultimately may be used to identify a new and useful healthy nutritional and lifestyle course of action.
