What This Tay-Sachs Blood Test Checks

This is a Tay-Sachs enzyme test — it measures Hexosaminidase A (Hex A) enzyme activity in your blood.

Absent or very low Hex A → supports Tay-Sachs disease diagnosis

Reduced Hex A → indicates Tay-Sachs disease carrier status

Also screens for Sandhoff disease — a related enzyme deficiency

This is a blood enzyme activity test. It does not analyze DNA.

Who Should Consider Tay-Sachs Testing & Screening

Individuals of Ashkenazi Jewish descent

Anyone planning a pregnancy or currently pregnant

Those with a family history of Tay-Sachs disease

Partners of a known Tay-Sachs disease carrier

Anyone seeking Tay-Sachs carrier testing before conception

Those undergoing fertility treatment or genetic counseling

Individuals with an abnormal newborn screening result

Anyone pursuing Tay-Sachs disease diagnostic testing

Tay-Sachs Prenatal Testing & Pregnancy

Tay-Sachs testing during pregnancy — or before conception — is one of the most common reasons people order this test.

If both parents are carriers, each pregnancy carries a 25% chance of an affected child. Knowing your carrier status early gives you time to make informed decisions and access genetic counseling if needed.

This test is suitable for preconception screening and prenatal planning. If you are currently pregnant, confirm with your OB-GYN that enzyme activity testing is appropriate for your specific situation.

Is This the Same as Genetic Testing for Tay-Sachs Disease?

This test is not a DNA test and does not sequence your genes.

It measures Hex A enzyme activity in your blood — a clinically recognized method for Tay-Sachs disease carrier testing and disease assessment. Enzyme activity testing is a direct and established alternative to DNA analysis for assessing Tay-Sachs disease or carrier status.

FAQ - Testing For Tay-Sachs Disease

What does this Tay-Sachs enzyme test check?

It measures Hexosaminidase A (Hex A) enzyme activity in your blood — supporting Tay-Sachs disease assessment and identifying carrier status. It also screens for Sandhoff disease.

What does it mean to be a Tay-Sachs carrier?

A carrier has reduced Hex A activity but shows no symptoms. If both parents are carriers, each pregnancy carries a 25% chance of an affected child.

Is this the same as genetic testing for Tay-Sachs disease?

No. This is a blood enzyme activity test — not a DNA test. It measures Hex A enzyme function, which is a recognized method for assessing Tay-Sachs disease or carrier status without genetic sequencing.

Is this test relevant for testing during pregnancy?

Yes. Tay-Sachs prenatal testing and preconception screening are among the most common uses for this test. If currently pregnant, consult your OB-GYN to confirm the right testing approach.
