Predictive DNA testing is a new and growing field of research in genetics. In predictive DNA testing, a normal healthy looking person is diagnosed with genetic testing to predict their future risk of getting any disease.
Why is this test used?
The main aim behind this test is the thought that early diagnosis or identification of these risks can help in the prevention and treatment of such disease.
Who can provide a predictive genetic test?
Many Healthcare providers and home DNA testing companies provide this predictive test.
Different types of this test?
There are two different kinds of predictive tests available.
Presymptomatic test: this test is done to check whether an individual will develop symptoms of a disease or not. A positive result usually means the individual will show symptoms of the disease. For example, Huntington’s disease-linked mutations.
Predisposition test: this test is used to check whether an individual is more likely than others to develop symptoms of a disease. But this test doesn’t determine whether the person will get sick or not. This test is usually done to check mutations that are linked to breast cancer.
The important thing to note
To review the test you must have a health professional help you understand the results. This is important because the predictive test can affect:
Your future life plans
And your mental and emotional state
Also, the most predictive test doesn’t tell you about:
Whether the condition will develop
When it might occur
And at what level it will affect you.
