Secondary ID A test code used for billing and in test definitions created prior to November 2011

82594

NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.

Yes

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.
