Why do I need an AAT test?
You may need an AAT test if you are under the age of 45, are not a smoker, and have symptoms of lung disease, including:
Wheezing
Shortness of breath
Chronic cough
Faster than normal heartbeat when you stand up
Vision problems
Asthma that doesn't respond well to treatment
You may also get this test if you have a family history of AAT deficiency.
AAT deficiency in babies often affects the liver. So your baby may need an AAT test if his or her health care provider finds signs of liver disease. These include:
Jaundice, a yellowing of the skin and eyes that lasts for more than a week or two
An enlarged spleen
Frequent itching
