Diagnostic Testing

Diagnostic testing is critical for getting an accurate picture of the underlying pathology for each individual.

In functional and complementary medicine both general pathology and functional pathology are used. Functional pathology testing is useful in assessing the state of organ functioning, biochemical functioning and assessment, nutritional deficiencies or imbalances.

Macquarie Natural Health use the following pathology laboratories and specific testing:

Standard Pathology

Organic Acid Profile

The Great Plains Laboratory Inc

The Organic Acids Test (OAT) offers a comprehensive metabolic snapshot of a patient’s overall health with over 70 markers. Many people with chronic illnesses, fatigue and neurological disorders often excrete several abnormal organic acids in their urine. The cause of these high levels could include oral antibiotic use, high sugar diets, immune deficiencies, acquired infections, as well as genetic factors. It is the gold standard assessment of metabolic, toxicant, and nutritional status.



The Great Plains Laboratory Inc.

Because exposure to environmental pollutants has been linked to many chronic diseases, The Great Plains Laboratory has created GPL-TOX, a toxic non-metal chemical profile that screens for the presence of 172 different toxic chemicals including organophosphate pesticides, phthalates, benzene, xylene, vinyl chloride, pyrethroid insecticides, acrylamide, perchlorate, diphenyl phosphate, ethylene oxide, acrylonitrile, and more.


Food Sensitivities


Symptoms of IgG mediated food intolerance (Type 3 allergy) can be general or specific, and may show up many hours or up to 3 days after consumption of a trigger food, making the culprits extremely difficult to identify without testing.


Faecal Microbial Analysis (FMA)


FMA can help identify an imbalance in gut flora that causes health problems. Due to the diversity of faecal microbiota, a number of selected key micoorganisms are measured. The tests are accredited with Australia’s National Association of Testing Authorities and the Royal Australasian College of Pathologists.

DUTCH Hormone

Precision Analytical.

This is a game changer in the world of hormone testing. It provides the most comprehensive look at adrenal and sex hormones in one test. It measures the metabolites that excreted from hormones to a better understanding of what is actually getting into cells.


Pyrrole Screening

Applied Analytical Laboratories

Areas of expertise include specialist biochemical tests (including urinary pyrrole analysis), water and wastewater analysis, and chemical assessments. We use Applied Analytical Laboratories to assess possible biochemical imbalances that influence mood disorders, anxiety, learning problems, depression and other mental or behaviour disorders.


Pfieffer Screening

Evaluation and management of biochemical imbalances, such as zinc, copper, methylation marker are associated with the symptoms of developmental, learning and behaviour disorders or anxiety, depression or mental illness

Advanced Cholesterol
