Medical Laboratory Technology is a profession that combines the challenges and rewards of medicine with laboratory science. Medical laboratory Technologists perform complex and varied laboratory analyses, and use critical thinking skills in determining the accuracy and validity of test results. They recognize the interdependency of testing information and possess the knowledge of physiologic and pathologic conditions affecting results in order to support medical decisions. In diverse health care settings, clinical laboratory scientists provide test results used by such practitioners as physicians, nurses, nurse practitioners, and physicians assistants, in determining: the presence, extent, and causes of disease; monitoring therapy; and evaluating testing protocols to insure optimum and safe public health applications.
