@lclark918, Alpha-1-antitrypsin (AAT) is a protein produced in the liver that protects the body's tissues from being damaged by infection-fighting agents released by its immune system. In alpha-1 antitrypsin deficiency, the body’s normal production of AAT is reduced.

Your report states "AAT variants are genetically determined and can be associated with lung and liver injury. ... AT phenotype analysis is suggested." This means that the lab suggests that you get tested further for alpha-1-antitrypsin because it can lead to lung issues. If you have the AAT variant, it may be inherited and passed on to children, if you have any.

Definitely discuss this with your doctor at your next appointmen.
