What does it mean to test positive (be susceptible) to a particular disease?
In the event that you test positive for a particular disease, it implies that there are mutations or defects in your genes which make you more likely than the average person to develop that disease. However, you should be aware that a positive genetic test result is only one factor in determining risk for a particular disorder. Other factors need to be considered, including environmental, lifestyle and diet factors. Therefore it is in no way a confirmation that you have developed, or will definitely develop the disease. However, what you should do is consult with your doctor regarding the other risk factors, and the ways in which you can try to avoid them.
