Functional Blood Chemistry Analysis

Functional Blood Chemistry Analysis, or FBCA, is a powerful tool for Naturopathic Doctors to assess clients, identify imbalances and balance the body early.

The prevailing myth about blood chemistry analysis is that it’s a diagnostic tool only used for determining the presence or absence of disease. This, however, isn’t true.

What Is Functional Blood Chemistry Analysis?

“Normal” Isn’t Optimal


Under allopathic approaches, a practitioner might take one blood test, note that a given biomarker isn’t low or high enough to indicate the presence of disease, and reassure the patient that everything looks normal — even if that patient is still experiencing dysfunction like fatigue, pain or inflammation.  However, this kind of black-and-white thinking — where the client is either healthy or sick with a clinical condition — leaves many dysfunctional, unhealthy clients to suffer.

That’s because the broad reference ranges used by the laboratories that analyze blood samples are based on averages, not on actual health. These ranges are calculated based on the average values found within roughly 95% of a sample population. When faced with these broad ranges, an allopathic practitioner might conclude that a biomarker falls within normal limits.

Functional Blood Chemistry: Optimal Ranges for Optimal Health


Functional health practitioners use blood chemistry analysis by looking at much tighter, optimal ranges that represent the ideal level for a given biomarker. These ranges are empirically correlated with real health outcomes, and by tracking their clients’ progress toward or away from those ranges, practitioners help guide their patients toward optimal health — not merely “normal” health

To make even greater use of functional blood chemistry’s optimal ranges, practitioners can track their client's blood test results over time and observe as biomarkers shift towards or away from the optimal range.  When a biomarker strays above or below that range, practitioners can use this as a sign that an intervention is needed, whether that’s the recommendation of supplements, food and lifestyle changes, or any other type of intervention.

Functional Health Reports Personalized for Each Client

Based on your test results a personalized report will be professionally generated just for you which will include:

  • Blood Test Results -  This report lists the results of your tests and whether or not a given biomarker is outside of the optimal range or standard lab range. You will also receive a brief description of why each biomarker might be elevated or decreased.

  • Functional Body Systems Assessment - an algorithmically derived assessment of dysfunction risk for each major functional body system such as the immune, cardiovascular and others.

Report Designs Mockups-01.webp
  • Macronutrient & Individual Nutrient Status - Using the results of your blood test, see the likelihood of dysfunction based on your overall macronutrient status like vitamin, mineral and protein intake, digestion, absorption, assimilation and cellular uptake.

  • Health Improvement Plan - The Health Improvement Plan report summarizes the top areas covered by the Functional Health Report that require attention. Each major area links to a detailed description and individual explanation of why it's an area of concern and what might be behind the results.
