FAQs

Frequently Asked Questions

Functional testing evaluates how your body is performing right now. Unlike genetic testing (which is fixed), functional tests measure real-time biomarkers like nutrient levels, hormone balance, gut health, and toxic load. They help identify root causes of symptoms and guide targeted, personalised interventions.

Our functional tests use clinically validated biomarkers and are run in certified laboratories with strict quality controls. Many tests use gold-standard methods like LC-MS/MS (liquid chromatography–mass spectrometry) or ELISA for hormone and nutrient testing, 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.

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

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 clearly provided.

It ranges from 3 days to 2 weeks, depending on complexity

You will receive your results securely through our patient portal, followed by a consultation to interpret the findings and guide your next steps.

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

  • Personalised fitness or nutrition goals

  • A desire to understand how their body functions at a deeper level

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.

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.

2. Diagnostic Tests: Prenatal diagnostic tests are more invasive and definitive. They are performed when a screening test indicates a higher risk of a genetic disorder or when there are other indications for a diagnostic assessment. Common diagnostic tests include chorionic villus sampling (CVS) and amniocentesis. These tests directly examine the genetic material of the fetus, providing a definitive diagnosis of genetic conditions, chromosomal abnormalities, or other genetic disorders.

No. These tests are meant to complement your regular healthcare — not replace it. Genetic and functional testing provides deeper, personalised insights, but ongoing check-ups with your GP or specialist remain essential for overall care.
