Tay-Sachs Test

Serum Hexosaminidase A and B

What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

• Using birth control pills, which may lower your hexosaminidase A level.
• Pregnancy. Being pregnant can also lower your hexosaminidase A level.
• Having a recent blood transfusion. If you have a blood transfusion from a blood donor who has normal levels of hexosaminidase A, your level may temporarily be higher than usual.
