Genetic tools, Kuhnean theoretical shift and the geneticization process.

The growing use of genetic tests in medical practice has a strong influence on some widespread notions of health and unhealth. Two consequences of this phenomenon are: (i) important changes in the meaning of these current notions and, therefore, (ii) the arrival of a new taxonomy or rearrangement for the so-called "health-concepts". This paper attempts to demonstrate that both facts fuel a theoretical change that might be considered a model of scientific Kuhnean change in a fundamental aspect. On the other hand, this theoretical shift process offers the basis for approaching a present-day controversy, i.e. whether Western society is going through a period of geneticization or not, from a new perspective.
