Seriously, you said it yourself-----they are PROBABILITY tests based on DNA sequences that are associated with some diseases. If a disease is a single gene abnormality, the tests are pretty definitive---such as sickle cell or B-thallasemia. But most of the diseases that you and I would be interested in are multifactorial----heart disease, cancers, diabetes, etc. Now the testing becomes less definitive and probabilities take on a bigger role. So common sense needs to prevail-----don't make any final arrangements based on these tests. Then, if you have a higher probability of heart disease, stay fit, maintain ideal weight, and limit fat/cholesterol. If you have a higher probability of lung cancer---DON"T SMOKE!
