  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Both

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

  • Acid alpha glucosidase [Enzymatic activity/volume] in DBS
  • Acid alpha glucosidase
  • This is a newborn screening test to detect enzymatic activity in dried blood spot to screen for Pompe disease, which is an inherited disorder caused by the buildup of a complex sugar called glycogen in the body's cells. The accumulation of glycogen in certain organs and tissues, especially in muscles, impairs their ability to function normally. Major features of Pompe disease include muscle weakness, heart abnormalities, and breathing problems. This disorder is caused by mutations in the GAA gene; it has an autosomal recessive pattern of inheritance.
