Define genetic testing, list potential barriers to genetic testing, what is the greatest potential barrier to genetic testing and why?

Expert Solution

Answers:

Definition:

The study of a person's DNA in order to identify genetic differences or susceptibility to particular diseases or abnormalities.

Barriers:

Physical risks involved is negligible in case of blood and cheek swab tests
Prenatal testing has a small risk of pregnancy loss (miscarriage).
It may have emotional, social and financial risks.

Greatest Potential Barrier:

Many of the risks associated with genetic testing involve the emotional, social, or financial consequences of the test results. People may feel angry, depressed, anxious, or guilty about their results. In some cases, genetic testing creates tension within a family because the results can reveal information about other family members in addition to the person who is tested.

Genetic testing can provide only limited information about an inherited condition. The test often can't determine if a person will show symptoms of a disorder, how severe the symptoms will be, or whether the disorder will progress over time. Another major limitation is the lack of treatment strategies for many genetic disorders once they are diagnosed.
