Pompe Disease, Blood Spot

Useful For Suggests clinical disorders or settings where the test may be helpful

Evaluation of patients with a clinical presentation suggestive of Pompe disease (muscle hypotonia, weakness, or cardiomyopathy) outside of the newborn screening setting

Highlights

This test is used to diagnose Pompe disease and is based upon a ratio calculated between the creatine (Cre) and creatinine (Crn) ratio and the activity of acid-alpha glucosidase (GAA).

 

This test can help differentiate true cases of infantile and late onset Pompe disease from false-positive cases such as carriers and pseudodeficiency of GAA enzyme.

 

A positive test result supports the utility of follow-up molecular genetic analysis of the GAA gene.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
