If a physician would say, “I need to complete a DNA test on you because I might be suggesting a particular medical treatment or the withholding of medical treatment, but I'd like to really take a look at your DNA to see perhaps how this might negatively or positively affect your health condition by authorizing or withholding a treatment,” that of course would be predictive. Under that circumstance, he's still treating a health care condition of an individual and he would be protected in doing that.
