Food sensitivity testing
This test measures your body’s immune response to foods to help provide guidance on what types of food may be the best to choose for an elimination diet. It measures your immune system’s IgG reactivity to foods, which can help guide a temporary elimination diet. This test does not test for food allergies. Food allergies are mediated by a different antibody called IgE.
Gut permeability testing
Intestinal Permeability Assessment is a powerful noninvasive gastrointestinal test assessment of small intestinal absorption and barrier function in the bowel. The small intestine uniquely functions as a digestive/absorptive organ for nutrients as well as a powerful immune and mechanical barrier against excessive absorption of bacteria, food antigens, and other macromolecules. Both malabsorption and increased intestinal permeability (“leaky gut”) are associated with chronic gastrointestinal imbalances as well as many systemic disorders.
Increased intestinal permeability (leaky gut) of the small intestine can:
- Increase the number of foreign compounds entering the bloodstream
- Allow bacterial antigens capable of cross-reacting with host tissue to enter the bloodstream, leading to auto-immune processes
- Enhance the uptake of toxic compounds that can overwhelm the hepatic detoxification system and lead to an overly sensitized immune system
Leaky gut has been observed in a range of disorders such as:
- Inflammatory Bowel Disease (IBD)
- Food allergy
- Inflammatory joint disease
- Chronic dermatologic conditions
Intracellular micronutrient testing
“Micronutrients” collectively refer to essential vitamins and minerals necessary in trace amounts for health. Clinical deficiency states (states occurring after prolonged consumption of a diet lacking the nutrient that is treated by adding the nutrient to the diet) have been reported for vitamins A, B1, B12, C, and D, selenium, and other micronutrients. Classic nutritional deficiency diseases are uncommon in the United States; most people derive sufficient nutrition from their diets alone or in combination with over-the-counter multivitamins.
This medical policy addresses laboratory tests that measure the intracellular levels of micronutrients. This testing, also known as intracellular micronutrient analysis, micronutrient testing, or functional intracellular analysis, is sometimes claimed to be superior to serum testing because intracellular levels reflect more stable micronutrient levels over longer time periods than serum levels, because intracellular levels are not influenced by recent nutrition intake. However, the relation between serum and intracellular levels of micronutrients is complex. The balance of intra- and extracellular levels depend on a number of factors, including the physiology of cellular transport mechanisms and the individual cell type.
Telomere cellular age testing
Telomeres are sections of genetic material at the end of each chromosome whose primary function is to prevent chromosomal “fraying” when a cell replicates. As a cell ages, its telomeres become shorter. Eventually, the telomeres become too short to allow cell replication, the cell stops dividing and will ultimately die—a normal biological process. A telomere test can determine the length of a patient’s telomeres in relation to the patient’s age.
28-Day saliva hormone testing
This hormone test is a comprehensive assessment of estradiol, progesterone, and testosterone spanning a full 28 days. Hormone imbalances revealed in this hormone test profile can help illuminate root causes of disorders such as premenstrual syndrome (PMS), infertility, and menstrual irregularities. This hormonal test analyzes 11 saliva samples of a 28–day period.
Hormonal balance is the key. Research has long shown that fluctuating levels of estradiol, progesterone, and testosterone play a major role in a woman’s overall health affecting:
- Menstrual cycle
- Mood swings
- Sleep patterns
- Appetite level
- Sex drive
Chronic hormonal imbalances are implicated in disorders such as:
- Polycystic Ovary Disease
DUTCH hormone testing
The DUTCH test stands for Dried Urine Test for Comprehensive Hormones— it’s the most extensive profile of sex and adrenal hormones to assess hormone imbalances.
