A screening procedure that tests whether a person has a genetic make-up that is linked with a particular disease. If so, the person may either develop the disease or pass it on to his or her oﬀspring. When an individual has been found to carry a genetically linked disease, he or she should receive genetic counselling from an expert in inherited diseases.
Genetic screening is proving to be a controversial subject. Arguments are developing over whether the results of such screenings should be made available to employers and insurance companies – a move that could have adverse consequences for some individuals with potentially harmful genetic make-ups. (See GENES; GENETIC DISORDERS.)
