Genetic Test

Results

A genetic test examines a DNA (deoxyribonucleic acid) sample of a person's cells for abnormal genes, or analyzes the number, arrangement, and characteristics of the chromosomes.

The results of genetic testing depend on the type of test done. Genetic testing is used to:

• Diagnose an inherited disease.
• Provide information about how likely it is that you will develop a disease in the future.
• Determine whether you are a carrier of the disease.
• Provide information about the severity of an inherited disease.
