Beyond Standard Pathology
Standard GP blood work tests for disease states — outside-range values indicating clear dysfunction. Functional testing looks at optimal ranges, not just abnormal ranges, and uses tests not routinely available through Medicare.
For example, a standard thyroid test measures TSH only. A functional thyroid panel adds T3, T4, reverse T3, and thyroid antibodies — a far more complete picture of thyroid health.
Common Functional Tests We Use
Frequently ordered tests include:
- DUTCH comprehensive hormone panel: Oestrogen metabolism pathways, progesterone, androgens, cortisol, and DHEA
- Comprehensive digestive stool analysis (CDSA): Microbiome diversity, pathogens, digestive enzymes, inflammatory markers
- SIBO breath test: Hydrogen and methane gas produced by small intestinal bacterial overgrowth
- Organic acids test: Mitochondrial function, B vitamin status, neurotransmitter metabolites
- Hair tissue mineral analysis: Mineral balance and heavy metal burden
Cost and Availability
Most functional tests are not Medicare-rebated and are paid for out-of-pocket. Costs vary from $150–$500 depending on the test. We only order tests whose results will meaningfully change the treatment plan — not as a blanket screening exercise.
