Information about genetic susceptibility is particularly complex in the case of apoE. Therefore, it is recommended that research volunteers and their families receive genetic counseling before and after testing. Through counseling, families can learn about the genetics of AD, the tests themselves, and possible meanings of the results. This information may help families decide whether or not to take part in research. Depending on the study, research volunteers may have the opportunity, during counseling, to learn the results of their apoE testing. A primary goal of genetic counseling is to explore the consequences of such knowledge for people with AD and their families.
