A natural approach to functioning optimally
Functional Diagnostic Nutrition® (FDN) 

Reed Davis is the founder of Functional Diagnostic Nutrition® (FDN) which is a process that utilizes a series of lab tests to identify malfunctions at the subclinical level within the hormone, immune, digestion, detoxification systems.

It is a type of investigative strategy that allows us to discover hidden stressors and healing opportunities so that we can return these systems to their normal functions. This is important since we can not reach optimal health otherwise. 

 Most clients have no idea what is causing their health complaints and neither do their doctors. They deal with symptoms for years because other providers don’t bother to look for the underlying cause.

FDN health detectives use functional diagnostic lab work to identify the dysfunctions at the causal level that are often either directly or indirectly related these symptoms. Examples of possible underlying issues that are uncovered in laboratory tests include adrenal fatigue, poor nutrient breakdown and absorption, hormone imbalance, oxidative stress, circadian rhythm problems, poor liver function, food sensitivities, and pathogens such as parasites, bacteria or yeast.

FDN practitioners do not diagnose conditions. Rather their purpose is to discover imbalances and recommend lab-guided all-natural strategies to rebuild health. They have helped thousands of people reach their best level of health in many years. Many clients have completely resolved their problems even if they were previously diagnosed with serious medical conditions.

BH #205 Functional Adrenal Stress Profile, Plus V 

The Functional Adrenal Stress Profile is a saliva test used to evaluate the adrenal glands and hormone balance.

It measures seven different hormones, including cortisol and DHEA, which complement each other. The total cortisol/DHEA ratio, as well as four different individual cortisol levels and their pattern throughout the day give us clues as to how well the body is coping with internal and external stressors.

When the body is under chronic stress, pregnenolone (the precursor to DHEA and its metabolites, including progesterone, testosterone, and the estrogens) is used to produce cortisol at the expense of these other steroidal hormones. This steroidal hormone imbalance in turn effects other main bodily functions, such as fat and protein metabolism, musculoskeletal health, and detox capability, so it is an important indicator of a person's overall health.

Hormones tested: Cortisol x 4, averaged DHEA-S (sulfated form of DHEA), Estradiol, Estriol, Testosterone (AM), Melatonin (bedtime), and Progesterone (bedtime)

BH #401H GI Pathogen Screen with H.Pylori Antigen 

The GI Pathogen Screen is a four-day stool test that checks for ova and parasites such as protozoa, flatworms, and roundworms; Cryptosporidium parvum, Entamoeba histolytica, and Giardia lamblia, and Helicobacter pylori antigens; bacteria, fungi, yeasts, occult blood; and Clostridium difficile colitis toxins A and B. The test is very thorough and accurate with no false positives.

An overgrowth of microorganisms that are normally present and the presence of those that are not normally present in the intestines are causes for concern. Parasite infections in particular can be destructive, resulting in chronic stress, raised cortisol levels, and inflammation.

Gastrointestinal (GI) tract infections are common and can be either symptomatic or without symptoms.

According to BioHealth, eight out of ten patients who seek care have one or more GI infections. Currently the two most prevalent infections are Helicobacter pylori, a bacterium that primarily lives in the stomach, esophagus and upper duodenum, and Cryptosporidium parvum, a parasite that primarily lives in the small intestine.

Mediator Release Test (MRT)  

The Mediator Release Test is a blood test that checks how well your immune system responds to 150 foods and chemicals. It is a functional live cell analysis that identifies the foods and chemicals that cause cells to react and release mediators, such as histamine and prostaglandins.. It measures the endpoint, the mediator release, by looking at the volumetric change in cells after they are exposed to a substance.

The test is performed by Oxford Biomedical Technologies, which has over 50 years experience in food sensitivity technologies.The test has excellent reliability and uses state of art technology.

Food sensitivities are different from allergies in that they are much more common and involve a large range of foods. They are an important source of inflammation and symptoms but are often undetected or misdiagnosed for years. It is a factor in most chronic illnesses so managing diet-induced inflammation is a foundational component of optimal health. Food sensitivities are challenging for several reasons. First of all, the reactive foods could include healthy ones such as chicken, salmon, blueberries, and spinach. It just depends on the person. Also, it is hard to identify the foods that are triggering the reaction because they are usually dose-dependent (small amounts may not trigger a reaction) and they may have a delayed-symptom onset.

Common symptoms of food sensitivities include migraines, mental fog, mood swings, depression, fatigue, sleepiness during the day and insomnia at night, headaches, joint and muscle pain, water-retention, congestion, stuffy nose, constipation, bloating, gas, acid reflux, mouth sores, acne, and irritability.
