Genetic Screening

Also known as: genetic testing.

What is genetic screening?

Genetic screening refers to a wide variety of tests performed on blood and tissue to screen for genetic disorders. It can be performed on fetuses, pregnant women, and others to determine if they are carriers of a particular disease.

What happens during the procedure?

A routine blood draw is required. In fetal testing, an amniocentesis is the preferred method of obtaining the sample, which is then taken to the laboratory for testing.

Is any special preparation needed?

No special preparation is needed for the test unless it is being obtained by amniocentesis for fetal testing.

What are the risk factors?

Infection, bleeding and damage to surrounding organs and tissues are potential risks for any blood drawn. For invasive fetal testing, there is an increased risk of miscarriage (fetal loss).
