What is DNA?

DNA folds into paired packages called chromosomes. Chromosomes contain many genes. A gene is a section of DNA that holds the instructions to build a protein. People can have different versions of the same gene. Our bodies are made of around 24,000 genes, using around 3% of our DNA.

Proteins are essential for life and perform a huge variety of jobs, from controlling the function of a single cell, to determining the shape of our bodies.

DNA is the blueprint for life. Think of DNA as an assembly manual that is used to build each and every one of us.

We share very similar DNA with one another, 99% in fact. But it’s the 1% that makes us individuals, giving us different e.g. facial features, hair colour, height, etc…


A myDNA medication test is a PGx test that helps identify which medications are likely to be most suited to an individual. The test results are presented in a report for the healthcare professional to consider when deciding on the choice of medication for their patient.


PGx is the study of how genetic factors influence the way a person responds to medications. PGx combines the study of pharmacology (study of how drugs work in the body) and genomics (study of genes and their functions). PGx is now being used to help doctors select safe and effective medications for their patients based on their unique genetic makeup.

There are certain genes which contain instructions to build proteins called enzymes. These enzymes are involved in breaking down many medications in the body, primarily in the liver. People have different versions of these genes which produce enzymes with varying levels of activity (e.g. slow, normal or fast). As a result, people can vary in how slow or fast they break down and clear medications from their body, and this can influence how well a medicine works or the risk of side effects for that individual.

Although not all medications are processed by these enzymes, a myDNA Pgx test can provide information on a range of commonly prescribed medications, and indicate to your doctor whether there is anything additional they should be aware of if prescribing them. If you wish to clarify which medications are covered by each test, or have any other enquiries please call us on 1300 436 373.
