Hormonal imbalances
Follicle Stimulating Hormone (FSH): Plays a critical role in regulating the reproductive processes, such as ovulation and sperm production.
Luteinizing Hormone (LH): Works alongside FSH to control the menstrual cycle and ovulation in women, and sperm production in men.
Oestradiol: A form of estrogen, crucial for regulating the female reproductive system, menstrual cycle, and maintaining bone health.
Testosterone: The primary male sex hormone, important for muscle mass, energy levels, and libido, but also present in women at lower levels.
Thyroid Stimulating Hormone (TSH): Regulates thyroid function, influencing metabolism, energy levels, and overall hormonal balance.
Thyroxine (T4): The main hormone produced by the thyroid, essential for metabolism, growth, and development.
Triiodothyronine (T3): A more active form of thyroid hormone, playing a key role in regulating metabolism and energy use within the body.
These hormones work in tandem to maintain overall health, and imbalances can indicate underlying health conditions.
Non-food items tested
Plants and Trees: Alder, Apple Tree, Ash, Aspen, Birch, Buckwheat, Chamomile, Cherry Tree, Clover, Dandelion, Elder, Elm, European Beech, European Lime, False Acacia, Fireweed, Goldenrod, Hazel, Horse Chestnut, Jasmine, Juniper, Linden Tree, Oak, Poplar, Primrose, Ragweed, Rose, and more.
Animals and Insects: Bee, Canaries, Cats, Dogs, Deer, Ducks, Goose Feathers, Guinea Pigs, Hamsters, Horses, Mice, Mosquitoes, Pigeons, Rabbits, Rats, and Wasp.
Other Common Triggers: Dust, House Dust Mite, Wool, Leather, Rubber, and various forms of animal urine proteins, such as Mouse Urine Proteins.
Environmental Factors: Common grasses like Timothy Grass, Rye, and Bermuda Grass, as well as other natural elements like Mold, Tree Pollens, and Flea Dander.
This wide-ranging testing aims to uncover sensitivities to common allergens present in the environment, helping you identify and manage possible triggers for discomfort.
Metals tested for
Alkali and Alkaline Earth Metals: Lithium (Li), Sodium (Na), Potassium (K), Calcium (Ca), Magnesium (Mg), Strontium (Sr).
Transition Metals: Cobalt (Co), Copper (Cu), Nickel (Ni), Zinc (Zn), Manganese (Mn), Iron (Fe), Titanium (Ti), Chromium (Cr), Platinum (Pt), Palladium (Pd), Rhodium (Rh).
Precious Metals: Gold (Au), Silver, and Platinum (Pt).
Other Essential and Trace Elements: Boron (B), Molybdenum (Mo), Phosphorus (P), Iodine (I), Fluorine (F), Selenium (Se), Silicon (Si), Vanadium (V), and Zinc (Zn).
Toxic and Heavy Metals: Arsenic (As), Lead (Pb), Cadmium (Cd), Mercury (Hg), Antimony (Sb), and Bismuth (Bi).
Radioactive Elements: Uranium (U), Plutonium (Pu), Radium (Ra), and Radon (Rn).
Noble Gases and Other Elements: Helium (He), Hydrogen (H), Neon (Ne), Xenon (Xe), Krypton (Kr), Argon (Ar), Chlorine (Cl), Bromine (Br).
These metals are tested to monitor potential exposure and evaluate their presence in environments, food, or other sources, providing insights into their role in health and potential toxicity.
Gut biome tests
Probiotic Bacteria:
Lactobacillus acidophilus
Lactobacillus reuteri
Bifidobacterium bifidum
Bacillus coagulans
Streptococcus thermophilus
Streptococcus faecium
Other Bacteria:
Escherichia coli (E. coli)
Acidophilus bifidus
Streptomyces
These tests help evaluate the composition of gut bacteria, crucial for digestion, immunity, and overall health. Maintaining a balanced gut microbiome is vital for supporting various bodily functions and preventing diseases.
Digestive Health & Metabolism Analysis
Amylase: An enzyme responsible for breaking down carbohydrates into simpler sugars.
Pepsin: A digestive enzyme that helps break down proteins in the stomach.
Hydrochloric Acid: A strong acid that aids in protein digestion and the absorption of essential nutrients.
Bile Salts: Substances produced by the liver that assist in the digestion and absorption of fats.
Lipase: An enzyme that breaks down fats into fatty acids and glycerol.
Trypsin & Chymotrypsin: Enzymes that continue protein digestion in the small intestine.
Enterokinase: An enzyme that activates trypsinogen, leading to effective protein digestion.
Together, these components play a crucial role in breaking down food, absorbing nutrients, and maintaining efficient metabolic processes. This analysis helps identify potential issues with digestive efficiency and nutrient absorption.
Information
Have you been feeling any of these symptoms lately?
Itching in the mouth or throat

Additional Information
Home Food Intolerance Testing
There are several types of food intolerance tests, each with unique benefits and challenges. It’s important to choose the right one based on your needs:
Elimination Diet: This method involves removing all potential allergens from your diet for a period of time, then gradually reintroducing them one by one. While highly effective, it can be difficult to follow such a strict regimen.
Skin Prick Test: This test involves pricking your skin with a needle that’s dipped in a solution containing a potential allergen. If you react, the test can detect allergies and intolerances. It’s relatively easy to perform and provides quick results.
Blood Test: A blood test measures IgG antibodies, which are produced when your body reacts to certain foods. Elevated IgG levels may suggest an intolerance to specific foods.
Hydrogen Breath Test: This test measures hydrogen gas in your breath, which is produced when your body breaks down certain carbohydrates. High hydrogen levels may indicate an intolerance to those carbs.
Regardless of the method you choose, it’s important to consult with a healthcare professional to interpret the results. They can help you determine whether you have a food intolerance and suggest appropriate dietary changes. With the right guidance, you can minimize symptoms and improve your quality of life.
Understanding Food Intolerance
Food intolerance occurs when your body has difficulty digesting specific foods, leading to discomfort such as bloating, gas, and diarrhea. Although it’s not as severe as a food allergy, food intolerance can still make eating certain foods challenging.
Common types of food intolerance include:
Lactose Intolerance: Difficulty digesting lactose, a sugar in dairy products, is the most common food intolerance.
Gluten Sensitivity: A condition where gluten, a protein found in wheat, barley, and rye, causes digestive issues like bloating and gas.
Fructose Malabsorption: Difficulty digesting fructose, a sugar found in fruits and some vegetables, can lead to bloating and other digestive problems.
If you suspect you have a food intolerance, speak with your doctor. Several tests are available to pinpoint which foods trigger your symptoms. Once you know which foods to avoid, managing your symptoms becomes much easier. Dietary supplements are also available to help alleviate symptoms; consult your doctor or nutritionist to determine which supplements are most appropriate for you.
