AAT
Description
"Alpha-1 Antitrypsin (A1AT)" test checks for levels of a protein that protects tissues from inflammation-related damage. Low A1AT may point to a genetic deficiency that raises the risk for liver disease and lung conditions like emphysema. Doctors often order this test when symptoms include breathing issues, liver dysfunction, or a family history of A1AT deficiency. Results guide genetic counseling, lifestyle changes, or treatment planning. Ongoing monitoring helps manage symptoms and reduce complications tied to A1AT-related disorders.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
