Our test

You are unique

Your DNA is the instruction manual for every cell in your body. It influences how you look and how your body behaves.

The myDNA test finds the genes that determine how your body processes certain medications.

The results can reveal the right medication and the right dose for you.

This allows you and your healthcare professional to tailor the best treatment for you.


The myDNA test can help your healthcare professional choose the best medication and dose based on your unique DNA. This may help in:

  • Better treatment outcomes
  • Fewer harmful side-effects
  • Less trial and error in drug selection
  • Reduced spend on medications

How it works

The test is quick and painless.

A DNA sample is collected using a cheek swab and sent to a laboratory for analysis by an expert team of doctors, pharmacists and scientists.

Our report provides you with a comprehensive genetic profile that explains how your body responds to specific medications.


The test covers certain medications in the following classes:

  • Antidepressants
  • Antipsychotics
  • Pain medications
  • Anti-inflammatories
  • Reflux or stomach medications
  • Blood thinners

Our story

Your genetics partner for life

Associate Professor Les Sheffield founded My DNA Life because he recognised how advances in DNA testing could help patients receive a more targeted personalised medication treatment.

In 2007 he established the myDNA multi-gene test (previously DNAdose).

To date 10,000 tests have been conducted nationwide.

Bringing new discoveries to you

The area of genetic profiling is rapidly evolving with a huge amount of research being conducted around the world.

Our team is dedicated to providing you with the most up to date knowledge in the field.

This can help you to make more informed health and lifestyle decisions.

myDNA for You

Your DNA results have lifelong relevance and can help guide your future health and lifestyle choices.

Once you have received your results from your healthcare professional, you can securely access your results and other information tailored to your DNA via our secure online portal. This will include new information as it becomes available.

She has developed a particular interest in the areas of pharmacogenomics and mental health. She advises pharmacists and other health professionals how to incorporate pharmacogenomic testing into their practice.

Research indicates that up to one third of people may process certain types of medications too quickly, which can increase the risk of treatment failure or reduced efficacy

Statistics for CYP2D6 and CYP2C19 genotypes are quoted in the CPIC Guidelines Selective Serotonin Reuptake Inhibitors (August 2015) and are confirmed by the analysis of the results of approximately 4750 myDNA tests -
