Alpha-1 antitrypsin deficiency
How is AATD diagnosed?
AATD is diagnosed through a simple blood test that measures the level of alpha-1 antitrypsin in the blood.
Your child’s doctor may do other tests to check for liver disease as well. These can include:
- Ultrasound — to get a better view of your child’s liver
- Liver biopsy — to examine a sample of liver tissue under a microscope
