Predictive testing for multifactorial diseases
Predictive testing looks for genetic alterations associated with multifactorial diseases such as cancer or diabetes. Many people want to learn about their own genetic predispositions regardless of whether they are planning a family.
Predictive screening is not diagnostic; it can't tell you whether or not you will develop a disease. It only tells you whether you carry a gene mutation that puts you at higher risk for that disease than the general population.
People with a family history of illness often find it helpful to know their inherited risk so that they can make better decisions about their lifestyle and healthcare. A negative result can provide peace of mind, while a positive result can help you and your healthcare provider take steps to prevent the disease. Predictive screening also lets you know what risk factors you might pass on to your children.
