Beta Galactosidase GM1 / MPS IV B Blood Test

This test measures the levels of beta galactosidase GM1 in your blood.

• To diagnose and monitor a condition called GM1 gangliosidosis or MPS IV B

• To evaluate the activity of beta galactosidase GM1

• To confirm a diagnosis, assess disease progression, and monitor treatment effectiveness

This test may be recommended if you or your child have symptoms suggestive of GM1 gangliosidosis or MPS IV B, such as developmental delays, muscle weakness, or liver and spleen enlargement. It is also useful for individuals with a family history of these conditions or genetic risk factors.

Abnormally low levels may suggest the presence of GM1 gangliosidosis or MPS IV B.

During the test, a small sample of your blood will be collected. It will then be sent to a laboratory for testing.

Inform your doctor about any medications, supplements, or medical conditions you have that could potentially affect the test results. Also, tell them if you have any specific requirements.

Other tests that may be ordered alongside the Beta Galactosidase GM1 test include genetic testing to identify specific mutations associated with GM1 gangliosidosis or MPS IV B.
