Diagnosis & Tests
How is the disease diagnosed?
A parent or healthcare provider may think an infant has a problem after observing the child. When the disease is suspected, hexosaminidase A is measured in blood or other tissue. If the enzyme is deficient, diagnosis is confirmed. DNA testing is possible for Tay-Sachs disease. Diagnosis before birth is possible through amniocentesis.
