Genetic Disorders

Genetic tests are done by analyzing small samples of blood or body tissues. They determine whether you, your partner, or your baby carry genes for certain inherited disorders. Genetic testing has developed enough so that doctors can often pinpoint missing or defective genes. The type of genetic test needed to make a specific diagnosis depends on the particular illness that a doctor suspects. Many different types of body fluids and tissues can be used in genetic testing. For DNA based genetic testing, only a very tiny bit of blood, skin, bone, saliva or other tissue is needed.
