A genetic test is an analysis of your DNA which identifies changes in genes, chromosomes or proteins. They are used to identify increased risks of health problems, to choose treatments or to determine chances of developing a disease.
There are three types of tests which are commonly used:
Diagnostic testing is used to precisely identify the disease that is making a person ill. The results of a diagnostic test may help you make choices about how to treat or manage your health.
Predictive and pre-symptomatic genetic tests are used to find gene changes that increase a person's likelihood of developing diseases. The results of these tests provide you with information about your risk of developing a specific disease. Such information may be useful in decisions about your lifestyle and healthcare.
Carrier testing is used to find people who "carry" a change in a gene that is linked to disease. Carriers may show no signs of the disease; however, they have the ability to pass on the gene change to their children, who may develop the disease or become carriers themselves. Some diseases require a gene change to be inherited from both parents for the disease to occur. This type of testing usually is offered to people who have a family history of a specific inherited disease or who belong to certain ethnic groups that have a higher risk of specific inherited diseases.
Currently the most popular test is the MTHFR Gene Test. The MTHFR gene (Methylenetetrahydrofolate Reductase), is an enzyme that converts the folate you eat, via many steps, into the active form 5-MTHFR (5-Methyltetrahydrofolate). It is also required to metabolise or breakdown homocysteine. The MTHFR Gene mutation is associated with increased risk of hormonal conditions, anxiety and depression and cardiovascular disease. Our practitioners have completed training in this test.
