What is Functional Testing?
Functional testing evaluates how your body is performing right now by measuring real-time biomarkers, including nutrient levels, hormone balance, gut health, and toxic load.
Unlike genetic testing, which shows inherited traits, functional health testing reveals your current nutritional status, digestive function, immune system activity, and detoxification capacity.
Our online functional testing library makes advanced health screening accessible through convenient at-home sample collection.
Whether you're experiencing persistent symptoms or want to optimise your wellness, functional medicine testing provides personalised insights that guide targeted interventions.

Frequently Asked Questions
What is functional testing?
Functional testing evaluates how your body is performing right now. Unlike genetic testing (which is fixed), functional testing measures real-time biomarkers such as nutrient levels, hormone balance, gut health, and toxic load. They help identify root causes of symptoms and guide targeted, personalised interventions.
Who should consider functional testing?
Anyone interested in optimising their health, preventing disease, or understanding the root causes of chronic symptoms can benefit. These tests are particularly helpful for individuals with:
- Persistent fatigue, gut issues, or hormonal imbalances
- A family history of chronic diseases
- Personalised fitness or nutrition goals
- A desire to understand how their body functions at a deeper level
What functional tests do you have available?
JIVI offers a range of cutting-edge functional tests, including:
- Comprehensive hormone panels – for stress, thyroid, and sex hormones
- GI and microbiome testing – assess digestion, gut flora, inflammation
- Nutrient & micronutrient testing – detect deficiencies or imbalances
- Toxicity and heavy metal panels – evaluate environmental toxin exposure
- Inflammation and oxidative stress markers – track chronic disease risk
How accurate is functional testing?
Our functional tests use clinically validated biomarkers and are run in certified laboratories with strict quality controls, ensuring high sensitivity and specificity.
However, because functional tests reflect a dynamic state, timing, sample type, and preparation (e.g., fasting, menstrual cycle) can influence results. That’s why we provide clear preparation guidelines and offer follow-up interpretation with a clinician.
How are samples collected?
It depends on the type of test. Functional tests may require a blood draw, urine, stool, or saliva sample, depending on the markers being assessed.
We offer both in-clinic and at-home options for many tests, and all sample instructions are provided.
How long does it take to get my results?
It ranges from 3 days to 2 weeks, depending on the complexity of the test.
You will receive your results securely via email, and a follow-up consultation to interpret the findings and guide your next steps, if requested.
Are my results private and confidential?
Yes. All your results are handled with the highest standards of medical confidentiality and data protection. Only you and your assigned clinician will have access to your data. We comply with strict clinical privacy protocols and use secure, encrypted systems for storage and communication.
Can results vary overtime?
Functional test results can and often do vary based on diet, stress, sleep, medications, and environment. That’s why these tests are useful for tracking your body’s response and guiding ongoing lifestyle changes.
Do these tests replace regular health check-ups?
No. These tests are meant to complement your regular healthcare — not replace it. Functional testing provides deeper, personalised insights, but ongoing check-ups with your GP or specialist remain essential for overall care.
