Food Allergies

Most conventional testing for food allergies looks at an IgE, or immediate, response to foods. They, however, do not look at IgG food sensitivities that have a delayed onset. This means, that after you eat a certain food, it can take from days to weeks to develop symptoms. Food sensitivities can affect your long-term health and ultimately lead to chronic health issues if not discovered. Each person may exhibit symptoms far different from another individual with the same food sensitivity. A sample of symptoms associated with food sensitivities include:
  • Sinus congestion, postnasal drip, asthma
  • Chronic ear infections
  • Skin conditions such as eczema
  • GI issues such as gas, bloating, diarrhea

Comprehensive Stool Analysis

Over 80% of our immune system is located in our gut. Therefore, optimizing gut function plays a key role in supporting overall health. The intestinal tract contains significant amounts of bacteria which, when imbalanced, have been associated with IBS and IBD, immune disorders, diabetes, and cardiovascular disease. Balancing gut microflora is key for optimizing digestion and absorption of nutrients, as well as metabolic functions. Poor digestion and malabsorptin can lead to immune dysfunction, nutritional insufficiencies, mental/emotional disorders, and autoimmune diseases.

Nutritional Assessment

Identifying nutritional deficiencies can be essential for the prevention and management of chronic disease. This panel looks at nutrient status of vitamins, minerals, and antioxidants through lymphocytes, or white blood cells, setting it apart from standard serum testing.

Neurotransmitter Testing

The human nervous system contains very important chemical messengers called neurotransmitters. Neurotransmitters are key players in your thought processes, emotions (moods), and other essential body functions including sleep, energy, and fear. Our nervous system needs to function properly in order for you to remain healthy. Unfortunately, the nervous system can be easily disrupted through a number of factors:
  • Stress
  • Poor diet
  • Toxic chemicals
  • Infections
  • Genetics
These factors can cause the levels of neurotransmitters to become either too high or too low. Imbalanced neurotransmitters can lead to:
  • Depression
  • Anxiety
  • Insomnia
  • Fatigue
  • Behavioral problems (including ADD/ADHD)
The good news is that neurotransmitter levels can be measured and balanced naturally to improve your health and well-being.

Adrenal Testing

This test assesses the functioning of the body’s adrenal glands. The adrenals modulate our stress response and in doing so, produce a variety of hormones such as cortisol. Cortisol is released in varying amounts during a 24-hour time period, following a circadian rhythm. Four samples of saliva are collected from morning to night to determine if an abnormal adrenal rhythm is present. Ultimately, this helps determine the effects of stress on your adrenals and overall health. Symptoms of adrenal imbalance include:
  • Morning and/or evening fatigue
  • Increased susceptibility to infection
  • Insomnia
  • PMS and hormonal imbalance
  • Poor recovery from exercise
  • Chemical sensitivity
  • Depressed mood
  • Allergies
  • Unstable blood sugar
  • Low sex drive
  • Weight gain (especially belly fat)
  • “Burned out” feeling

Genetic Testing

DNA-based Weight Management Program

This weight management program takes your unique genetic makeup into account and provides you with diet and exercise strategies that are tailored to your genotype. This is not guesswork, one-size-fits-all or a fad diet of any kind – these are the only diet and exercise recommendations you will ever need again, because they are based on your DNA.

Genetics-Based Healthy Aging Program

An innovative healthy aging program that utilizes your genetic profile to provide nutrient, food, activity and lifestyle recommendations to keep you looking and feeling young longer.  Recently published research has linked numerous aging signs to genetic predisposition, and many of these indications may be addressed with DNA-based lifestyle changes.

Comprehensive Micronutrient Predisposition Analysis

Comprehensive analysis of your genetic predisposition to absorbing micronutrients in your diet. Even if you eat a perfectly balanced diet with plenty of naturally occurring vitamins and minerals, most of us have some difficulty in absorbing one or more micronutrients at the cellular level. Understanding your genetic profile for how your body likely processes key vitamins and minerals is an important step in developing a healthy nutrition program.

Genetics-Based Peak Athletic Performance Program

Health and activity performance improvement program based on your genetic profile. The best nutrition, workout and supplement regimens for you cannot be determined without understanding your genetic predisposition. Genetic links to sports injury risks, VO2Max, and other athletic traits are also now known and key to athletic performance. For average athletes wanting to be good and good athletes wanting to be great, GxPerform provides you with the food, nutrient and training recommendations to allow you to reach your potential.
