Gene testing is making the rounds, whether it is on Facebook, the Longevity magazine or your friend who heard about it in yoga last week. Many of our clients are also becoming curious and there seems to be some confusion around the new concept of gene testing. There are four different DNA tests: DNA Health, DNA diet, DNA oestrogen and DNA Sport.
The DNA Health tests for variations in your genes that have a significant effect on chronic diseases such as osteoporosis, diabetes, cardiovascular disease and cancer. DNA Diet tests genes that have an association to weight loss and body mass index (BMI). The DNA Oestrogen test determines how well your body detoxes oestrogen; this test can also give an indication of your risk for developing Breast Cancer. DNA Sport is a popular test among avid sportsmen or sportswomen, but this test is also invaluable in determining your susceptibility to injury. Each test provides tremendous insight on an individualized level.
Gene Testing FAQ:
1. Do I have to go for a blood test?
To do the gene test, all we require is a cheek swab. A simple, painless procedure that will take two minutes.
2. What is the best time of day to do the cheek swab?
There is no ‘ideal time’. The most important thing is that you avoid eating and drinking for 2 hours before your swab is done. If you have an appointment in the early morning, it is best to not brush your teeth until after the swab is taken.
3. How long do I have to wait for my results?
Once payment is made for the DNA test, it is sent to the DNAlysis labs in Johannesburg. It takes anywhere between 2-4 weeks to get the report.
4. Will medical aid cover the DNA testing?
Medical aid will not reimburse you for the DNA tests, however, depending on your medical aid plan, the expense of your referring practitioner will be covered.
5. Do I need genetic counselling before doing the tests?
All the genes tested are what we call ‘low penetrance genes’. What this means is that our diet, stress levels, exercise, medication and environment (all the epigenetic factors) affect the way in which these genes express themselves. There are genes tested in the DNA Health and in the DNA Oestrogen that are strongly linked to certain Cancers but you can opt to leave these genes out of the report if you’d prefer.
6. Do I need to have another test in 6 months or a year?
Your genes never change and so you will never have to go for another gene test. Nutrigenomics is a rapidly growing field and new research is being published everyday. It is always good to keep up to date with new information.
