Genetic Tests identify changes in our DNA. Such tests can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder. A test result that can show that a known disease-causing alteration is not present in a person can provide a sense of relief.
Doctors use genetic testing for several reasons.
Diagnosing carrier status for mutations in unborn and newborn babies
Determining if an individual is a carrier of any mutations & has a risk of passing it on
Pre-natal Screening of embryos for diseases
Testing for genetic diseases in adults before they cause
Diagnose patients for disease carrier symptoms
Determining the type/ dose of medicine, best suited for the patient
