Genetic testing

Genetic testing is a general term that can refer to several different types of tests:
 * DNA sequencing to find risk factors associated with genes, and risk of specific illnesses in off spring
 * Genetic testing to diagnose illness
 * Pharmacogenetics

Pharmacogenetics
By identifying genes which are linked to the metabolism of particular drugs or other substances, this aims to predict which drugs are best suited to individual people, and which may be potentially harmful.

Theory
Genetic testing cannot diagnose ME or chronic fatigue syndrome, but is being in research to help find which genes may be linked to developing the illness, in order to improve understanding of the illness and investigate potent treatments.
