Genetic testing

Genetic testing is a genetic 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

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.
