Order Tay-Sachs Disease Testing | Carrier TestTay-Sachs disease is a rare inherited condition caused by the absence or severe deficiency of an enzyme called hexosaminidase A, or hex A. This blood test measures hex A levels to help determine whether a person has Tay-Sachs disease or carries a genetic change associated with it.
About Tay-Sachs Disease Testing | Carrier Test in Riverside
Tay-Sachs disease testing examines enzyme activity in the blood to clarify carrier status or diagnose the condition.
Tay-Sachs disease results from changes in the HEXA gene, which provides instructions for producing the hex A enzyme. Without sufficient hex A, certain fatty substances accumulate in the brain and nervous system, leading to progressive neurological damage. The classic form typically appears in infancy, while other forms can present later in childhood or adulthood with varied symptoms.
This test measures hex A activity in a blood sample. A markedly reduced or absent level suggests Tay-Sachs disease, while an intermediate level may indicate carrier status. Because enzyme levels can overlap between categories, results are often interpreted alongside genetic testing and family history.
Carrier testing is commonly considered by individuals with a family history of Tay-Sachs disease or those in populations where certain HEXA changes are more frequent. Identifying carriers supports informed reproductive decisions. A healthcare provider can explain what a given result means and whether additional testing is appropriate.
