Unlikely you have it: It is unlikely you have it. I would suggest you save your money. You need to discuss this with your physician.

Symptoms...: Alpha 1 antitrypsin deficiency typically presents as chronic obstructive pulmonary disease, or copd, at a younger age. If members of your family have copd, and it was diagnosed younger than usual (like 20s-30s, for example), then it would be reasonable to get tested. But, if neither you nor family members have been diagnosed with copd, then it is unlikely you have Alpha 1 antitrypsin deficiency.
