WellNest offers genetic testing including DNA Core, DNA and Epigenetic testing, and Medcheck pharmacogenomics. DNA Core reports on gene-environment interactions and offers summarised guidance across core wellness areas, while Medcheck reports on how your body may metabolise over 100 medications.

These tests report predispositions and tendencies, not certainties. A genetic predisposition is not a diagnosis and does not mean a condition will develop. Results are designed to help inform preventive and prescribing decisions made with your clinician, considered alongside your full health picture.

Genetic results can be nuanced, so we review them with you in a consultation rather than leaving you to interpret a report on your own.

Our longevity-focused tests include TruAge, a methylation-based test that estimates your biological age relative to your chronological age, and the NAD Profile, a dried blood spot test measuring NAD+ and related metabolites involved in cellular energy and DNA repair signalling.

These tests are used for benchmarking and tracking over time. They estimate patterns linked to ageing and may show how lifestyle factors such as sleep, stress, diet and exercise can influence those markers. They are not a diagnosis of any disease and do not predict lifespan.

Many people find biological age testing most useful when repeated periodically so trends can be tracked alongside changes in sleep, stress, diet, exercise, body composition and recovery.

A WellNest clinician can advise whether this type of testing suits your goals and how often retesting may make sense.

Yes. For gut health we offer the GI-MAP stool assay, which screens for microbes that may disturb normal microbial balance, and the Organic Acids Test, which gives a metabolic snapshot across more than 70 markers, including indicators that may point to yeast or bacterial overgrowth.

For hormones, the DUTCH Adrenal and DUTCH Complete panels map daily cortisol patterns and, in the case of DUTCH Complete, sex hormones such as oestrogen, progesterone and testosterone with their metabolites. DUTCH Complete is available from ages 12 and up.

• GI-MAP and the Organic Acids Test focus on gut and metabolic markers.
• DUTCH panels focus on adrenal and sex hormone patterns.

Results from these tests are interpreted by your clinician in context. They are designed to help inform a tailored plan, not to diagnose a condition on their own.

Preparation depends on the test. Standard Bloodwork, for example, may require a 12 hour fast where glucose or lipids are included, avoiding alcohol for 24 hours, and staying well hydrated. Other tests, such as the Mitochondrial test or the Physiological Readiness Scan, have their own guidance around exercise, caffeine and timing. We share the exact instructions for your test before your appointment.

Some samples are collected at our Bree Street clinic, while certain specialist panels are processed through our partner laboratories. Turnaround varies by test, and we book time to walk you through your results once they are ready.

To get started, book a consult with a WellNest clinician through our booking portal or contact the clinic. They can confirm which tests suit you, how to prepare, and what to expect from your results.
