Functional Lab Testing

Lab Testing Options

These are the most common tests ordered. Other tests may be available on request.

GI-MAP

This test provides a comprehensive map of your microbiome (gut health). It measures your zonulin levels to determine whether you may have “leaky gut”, which is at the root cause of many chronic symptoms and conditions.

It provides information on the balance of bacteria, and the presence of pathogenic bacteria, fungi, viruses, and parasites.

This test is beneficial for anyone experiencing the following:

• IBS/IBD

• Digestive symptoms such as bloating, diarrhoea, constipation, abdominal cramps or pain

• SIBO

• Allergies

• Food sensitivities

• Fatigue

This is the best test to start with for most people.

This is a stool test that you complete at home.

SIBO BREATH TEST

The SIBO Lactulose Breath Test helps identify SIBO or Small Intestinal Bacterial Overgrowth, which is behind many common digestive symptoms.

This test is beneficial for anyone experiencing the following:

• Digestive symptoms like diarrhoea, constipation, abdominal cramping, bloating, burping and gas

• Reflux, GERD or GORD

• Food sensitivities

• Joint pain

• Skin rashes

• Iron and B12 deficiency

• Respiratory symptoms such as asthma

For most people, I’d recommend starting with the GI-MAP. If you have delayed bloating that starts 2+ hours after eating, this test may be right for you. If you’d like guidance on whether to take the GI-MAP or SIBO test, email us on hello@frandargaville.com.

This is a breath test that you complete at home.

FOOD SENSITIVITY TESTING

Are you experiencing symptoms but can’t put your finger on what’s causing them? Or maybe you’re having trouble identifying your “trigger foods”.

Food sensitivities can contribute to many symptoms - even seemingly unrelated symptoms such as fatigue and brain fog.

My preference is to start with an elimination diet as this is the gold standard for identifying food sensitivities, but if you’ve tried that and are still struggling, this can be a helpful tool.

You can even be sensitive to even the healthiest of foods, like fruit and veggies, which makes it difficult to identify problem foods. This is made even more challenging by the fact that the symptoms of IgG mediated food intolerances are delayed, and therefore can’t be easily linked to a particular food.

This test is beneficial for anyone experiencing the following:

• IBS/IBD

• Digestive symptoms such as bloating, diarrhoea, constipation, abdominal cramps or pain

• Fatigue

• Brain fog

• Allergies

• Skin conditions such as eczema or acne

This is a blood test. You are sent the kit to your home, and you will take it to a local pathology clinic to have the test done.

STRESS AND ADRENAL HORMONES

When your body is under stress, or you’re experiencing long-term impacts of stress such as fatigue, anxiety or brain fog, adrenal testing gives us an understanding of your body’s stress response and the state of your adrenals and HPA axis. 

This test is beneficial for anyone experiencing the following:

• Anxiety

• Headaches

• Brain Fog

• Fatigue

• Salt, sugar or caffeine cravings

• Low moods

• Lack of stamina

• Difficulty sleeping

• Thyroid dysfunction

• Impaired immune system

This is a saliva test that you complete at home.

HORMONE TESTING

If you have signs of hormonal imbalance, it’s important to get an understanding of what’s really going on.

Common signs of hormonal imbalance include:

• Weight gain or difficulty losing weight

• Fatigue

• PMS, painful periods and mood swings

• Acne and breakouts

• Difficulty sleeping

This is a dried urine and/or saliva test that you complete at home.
