What is the impact of a medical malpractice on an employee's privacy?

In light of our society's concern for the security of one's person, see, e.g. Terry v. Ohio, 392 U.S. 1, 9, 88 S.Ct. 1868, 1873, 20 L.Ed.2d 889 (1968), it is obvious that this physical intrusion, penetrating beneath the skin, infringes an expectation of privacy that society is prepared to recognize as reasonable. The ensuing chemical analysis of the sample to obtain physiological data is a further intrusion of the tested employee's privacy interests.
