Useful For Suggests clinical disorders or settings where the test may be helpful
Presymptomatic identification of disorders to allow for early initiation of treatment and consequent improvement in the long-term prognosis of affected patients.
Early diagnosis may also minimize complications and help avoid unnecessary diagnostic testing and identify families for whom prenatal genetic counseling may be helpful.
