Functional Tests Explained

Functional Tests Explained

Through a series of functional lab tests we identify malfunctions in the body and uncover the root cause of health problems. We use this information to create a tailored plan to help rebuild your health over time.

Functional tests are designed to uncover malfunctions in these systems:

  • Hormone

  • Immune

  • Digestion

  • Detoxification

  • Intestinal Barrier System

Specific functional tests include: 

DUTCH (Dried Urine Test for Comprehensive Hormones)

Steroid Hormone Stress Profile

This test is the GOLD standard test for hormones now. It not only gives you the levels of sex hormones but the pathways they go down too. So you can see if they are going down the preferred pathway, cancerous or toxic pathway.

As well as testing the sex hormones; progesterone, estrogens, testosterone, DHEA it tests the stress hormone Cortisol, B vitamins, neurotransmitters and oxidative stress.

This test gives an insight into how your adrenals and sex hormones are functioning and a thorough view into the impacts of chronic stress on the body.  

  • Cortisol X 4

  • DHEA-S X 2 (averaged)

  • Estradiol

  • Estriol

  • Testosterone

  • Melatonin

  • Progesterone

Extensive Thyroid Profile


Thyroid abnormalities are one of the most common endocrine disorders affecting millions worldwide. Thyroid hormones are well known for their role in basal metabolic rate, development and growth. Hypothyroidism affects approximately 4-5% of the population whilst estimates for hyperthyroidism are 0.4-2%.

CDSA – Comprehensive Digestive Stool Analysis


This test will evaluate the function of your gastrointestinal tract providing a comprehensive picture of your gut health. The analysis investigates digestion + metabolism + pancreatic function + the balance of beneficial bacteria + presence of pathological bacteria, yeast and parasites. 

PCR – Multiplex Pathogen Test


This test offers a sensitive method for the detection of ten major enteric pathogens. Our faecal PCR test detects parasite and bacterial DNA, making it a more accurate technique than a standard Micro, Culture and Sensitivity (MC&S) that would normally be requested.

Intestinal Permeability - Leaky Gut

Changes in intestinal permeability are associated with many health conditions including autism, autoimmune disorders, food sensitivities and inflammatory bowel disease. This ‘leaky gut’ causes disease because the perturbed intestinal barrier allows toxic molecules to enter the bloodstream and poison the body. 

ALCAT® Intolerance Tests (Blood NaCit)

Intolerances/Sensitivities to foods + food additives + food chemicals + environmental chemicals + herbs/dietary supplements + molds can cause a wide range of symptoms and disorders. The ALCAT® diagnostic system detects changes in the size and number of leucocytes (i.e. immune cells) in response to exposure to the offending foods, chemicals, additives, herbs and molds.

IgG – Allergy panel

Food sensitivities can cause a wide range of symptoms and disorders. The foods that cause these delayed reactions are often hard to diagnose because of the time between consumption and the physical reaction. The IgG food allergy test offers a useful tool for detecting the foods causing this response. Your results provide a precise and effective starting point for dietary manipulation.

Available IgG Panels:

  • 96 General (Western) Foods

  • 96 Asian Foods

  • 16 Inhalants

  • 95 Vegetarian Foods

  • 48 Herbs & Spices

Helicobacter Pylori (Stool)

Helicobacter Pylori is a spiral-shaped bacterium that colonises the stomach and induces chronic gastritis, a long-lasting inflammation of the stomach.  It infects well over 30% of the world’s population making it one of the most common bacterial infections. The bacterium persists in the stomach for decades in most people and most individuals infected by Helicobacter pylori will never experience clinical symptoms despite having chronic gastritis (up to 85%). Approximately 10–20% of those colonised by Helicobacter pylori will ultimately develop gastric and duodenal ulcers. Helicobacter pylori infection is also associated with a 1–2% lifetime risk of stomach cancer and a less than 1% risk of gastric MALT lymphoma.


This test gives an insight into what is going on with digestion, toxicity and detoxification. It shows how much free radical damage has been done to cells from oxidative stress. It also shows liver health and if the liver is functioning efficiently.  

Candida Antibodies (Salivary)

A systemic candida infection may cause a diverse set of symptoms including poor concentration, premenstrual syndrome, fatigue, food sensitivities, irritable bowel, cystitis and, muscles and joint aches. Although yeast is found in everyone’s gastrointestinal tract, problems arise when the ratio of friendly bacteria to harmful microorganism is disturbed. This balance is upset by a modern lifestyle, including antibiotic and oral contraceptive use, stress and diets high in carbohydrates and sugar.

Extensive neurotransmitters Profile (Urine)   

The Extensive Neurotransmitter Profile is a urine test, assessing levels of 6 neurotransmitters: serotonin +GABA + dopamine + noradrenaline + adrenaline + glutamate. These neurotransmitters are the most researched in relation to their effects on mood disorders, hormones, sleep, glucose/insulin balance, pain perception, appetite and cognitive function.

Hair Mineral Analysis Test (HMAT)    

Hair metal and mineral analysis measures nutrient and toxic metal content of your hair. As the constituents of the hair are determined by the entry of substances from external sources and from substances that enter it from the blood stream, hair makes an ideal medium for analysis.

There are many more tests available, which we can discuss on a needs basis.
