DNA testing usually starts with a straightforward process: collecting a biological sample. Most consumer and clinical tests use a cheek swab or saliva sample, both of which are rich sources of cells from the inner lining of your mouth. These cells contain your complete set of DNA—the unique genetic code that acts as your body's instruction manual.

Our test is a genetic test and looks at DNA. Our reports highlight if you have any common genetic variations (SNPs) that occur in at least 1% of the population and result in differences in biological function, like nervous system function, hormone balance or detoxification, that can affect health. It doesn’t measure the products of those functions such as blood levels of hormones for example. Sometimes it can be useful to look at results of other types of test alongside nutrigenomic testing.

Sometimes you will find a 'No result' against a SNP. The missing results occur if the lab cannot successfully read the genetic code at that particular location. The lab will attempt multiple times to achieve a high level of statistical confidence for a specific result, but if that cannot be met, it is reported as 'No result'. It is not unusual to have a few SNPs missing across the whole profile.

The DNA test is a simple, non-invasive mouth swab that is easy to do at home.

This article explains the symbols and colour coding used on our reports. Most reports include a page titled 'How to Read the Report', which includes this same information.
