Genetic testing is a way to identify genetic disorders or changes in an individual's DNA that may lead to the development of a genetic disorder. There are several types of genetic tests that can be performed, including: (i) Carrier testing: This type of testing is done to identify whether an individual carries a genetic mutation that can be passed on to their children. (ii) Newborn screening: This type of testing is done shortly after birth to identify whether a newborn has a genetic disorder that may not be apparent at birth. (iii) Diagnostic testing: This type of testing is done to confirm a suspected diagnosis of a genetic disorder.
