Functional Medicine laboratory testing can be an extremely useful tool, especially when working with Digestive, Endocrine and Autoimmune conditions, it helps me to clarify, hone in and target the areas which are out of balance, in a precise and much more effective way. In addition testing provides an excellent way to monitor your progress, especially with Endocrine issues such as the Thyroid in particular.
Please Note:
I only recommend tests where I feel they are needed and work on a very individual basis.
I do not order tests without a Consultation as it is important to work with each person and apply the results of any tests together with an understanding of the individual including symptoms and past medical history as well as lifestyle and dietary habits.
The Laboratories I work with are professional, reliable and use the latest technology. They are utilised by Doctors as well as Nutritional Therapists, Medical Herbalists and Functional Medicine Practitioners.
Some of the more common tests I use in my practice
Discover the power of your gut with the Microbiome Explorer test from Microba. This advanced stool analysis provides a deep, comprehensive view of your gut microbiome – the trillions of microbes living in your intestines that play a vital role in your overall health. As we now understand, a healthy gut influences everything from digestion and immunity to mood and energy levels. Unlike many standard tests that focus on specific markers, this one reveals the true composition of your microbiome, giving you a clearer picture of what’s really going on inside.
How the Test Works
The Microbiome Explorer uses metagenomic next-generation sequencing (mNGS), a cutting-edge technique that examines the DNA (the genetic blueprint) from microbes in your stool sample. Bacteria, viruses, fungi, and other microbes leave traces of their own DNA behind, and this test reads and identifies them all. It’s like getting a full map of your gut’s microbial community, rather than just spotting a few suspects. This unbiased approach helps uncover imbalances or hidden issues that could be affecting your wellbeing.
The process is straightforward: you provide a simple stool sample at home, send it to the lab, and then after review you’ll receive a personalised treatment plan from Andrea.
What Does the Test Measure?
This test goes beyond the basics, analysing key aspects of your gut health.
Microbiome Composition
- A thorough DNA analysis of your gut’s microbial makeup, including bacteria, parasites, and even oral microbes that may have migrated.
- Identification of Candida species and other yeasts (mycology focus), helping spot potential overgrowths that can contribute to issues like bloating or fatigue.
Digestion Markers
- Pancreatic Elastase Enzyme: This measures how well your pancreas is supporting digestion. Low levels might indicate reduced enzyme production, leading to poor nutrient breakdown and symptoms like indigestion.
Immune System Markers
- SIgA (Secretory Immunoglobulin A): Your gut’s first line of defense against pathogens.
- If levels are very low, it could signal vulnerability to frequent infections or the development of food intolerances.
- If high, it might point to ongoing inflammation or infection, prompting further investigation.
Inflammation and Integrity Markers
- Calprotectin, Lactoferrin, and FIT Test (for occult blood): These detect signs of gut inflammation or hidden bleeding, which could stem from conditions like irritable bowel syndrome or more serious issues.
- Zonulin: A key protein that regulates the tight junctions in your intestinal lining. Elevated levels suggest increased intestinal permeability (often called “leaky gut”), which may allow unwanted particles to enter the bloodstream and trigger widespread effects.
Pathogen Detection
- A dedicated pathogen panel scans for harmful bacteria, viruses, parasites, and fungi that could be disrupting your gut balance and causing symptoms like diarrhoea, cramps, or unexplained weight changes.
Why I work with Microba
Over the last 20 years I have seen microbiome tests develop alongside the research. This test stands out for its depth and accuracy, helping us move from guesswork to targeted solutions. Whether you’re dealing with digestive symptoms, low energy, or immune challenges, understanding your microbiome can guide personalised steps with dietary enhancments, lifestyle changes, support with herbs and nutraceuticals. The results are clear, easy to interpret and can be a game-changer in your journey to better health.
SIBO Breath Test:
I have been trained in the art of interpreting the breath test for SIBO ( Small Intestine Bacterial Overgrowth) and find this a very useful test when looked at in conjunction with presenting symptoms.
The Organic Acid Test or OAT:
This is a very enlightened test which is incredibly useful for complex and chronic conditions.
I have undertaken advanced training in the interpretation and understanding of this test.
A Urine sample is sent to the lab where they check metabolites for many biochemical pathways including mitochondrial energy production, detoxification pathways, neurotransmitter turnover ( Dopamine and Serotonin) markers for oxidative stress and inflammation, mitochondrial B12 and folate levels, and markers for bacteria and yeast in the gut.
We can use this test also to give us an idea of where the bacteria is in the gut – large intestine or small intestine, helping me to decide on the best next step.
- DNA testing ( Nutri genomics):
This fascinating & extremely useful modality has really enhanced my practice.
I exclusively work with the UK company Lifecode GX and have undertaken the practitioner training for the following reports: ( click on the links for further information on each report) - Methylation
- Hormones
- Nervous System
- Detoxification
- Histamine
- Nutrient Core ( a comprehensive overview of nutrients and your genetic predisposition to utilising them)
Vitamin D:
By blood, in clinic or at home. A very important Vitamin with deficiency linked with many immune and autoimmune disorders as well as Hypertension.
Adrenal Stress Index:
Checks the levels of Cortisol and DHEA in the Saliva. Test performed at home, timed samples required. Kit provided by lab.
Complete Thyroid Screen:
This is a blood test which looks in depth at the thyroid function and checks Free T4, Free T3, TSH, Reverse T3 as well as the autoimmune antibodies present in Hashimotos and Graves Disease.
Female Hormone Panels:
A variety of tests available to check status of hormone levels in menstruating women as well as peri menopausal and menopausal women. Useful where there are fertility issues, PMS, Endometriosis, irregular or heavy/painful bleeding. The most common form of Female Hormone Test I use is the Dutch Test which is a urine spot, checking the metabolites of hormones found in the urine. This is a very sensitive and accurate test for the oestrogen pathways.
I also use blood tests to assess levels of oestrogen and other sex hormones.
Vitamins and Minerals:
I have access to many more Vitamin and Nutrient tests, see the blood test order page.
Stomach Acid (HCL):
Tests the level of ones stomach acid relating to digestion and impacting further systems. A simple test that is done at home at meal times, see the Stomach Acid (HCL) page..
Most kits are sent directly to you from the Laboratory once I have referred you, payment is made directly to the lab and the results are returned to me.
