Alpha-1 Antitrypsin Deficiency (Alpha-1) is a genetic condition that can lead to serious lung and liver disease. The good news is, diagnosis is straightforward. A simple blood test can determine if you have Alpha-1. But who should consider getting tested, and why is early diagnosis so important?
Who Should Consider Alpha-1 Testing?
Clinical guidelines recommend Alpha-1 testing for specific groups of people who are at higher risk or present certain symptoms. You should consider getting tested if you fall into any of these categories:
- Individuals with COPD (Chronic Obstructive Pulmonary Disease): This includes conditions like emphysema and chronic bronchitis, which obstruct airflow and cause breathing difficulties. Since Alpha-1 can mimic COPD, testing is crucial for accurate diagnosis.
- People with Unexplained Chronic Liver Disease: Alpha-1 can also affect the liver, leading to chronic liver issues. If you have liver disease without a clear cause, Alpha-1 testing is recommended.
- Those with Panniculitis: This is a skin condition characterized by inflamed fat tissue under the skin. Panniculitis can be associated with Alpha-1 in some individuals.
- Family Members of Individuals Diagnosed with Alpha-1: Alpha-1 is hereditary. Parents, siblings, children, and even extended family of someone with Alpha-1 are at increased risk and should be tested.
Considering Testing? Genetic Counseling Can Help
Before undergoing Alpha-1 testing, it can be beneficial to speak with a genetic counselor. The Alpha-1 Foundation provides free genetic counseling services with nurses who are experts in this area. Genetic counselors can explain the testing process, potential benefits, and any possible risks involved. This service helps individuals and families make informed decisions about testing. You can schedule a free consultation by calling 1-855-476-1227. Understanding the implications of genetic testing is a vital step in managing your health proactively.
The Importance of Alpha-1 Diagnosis
A significant challenge with Alpha-1 is that many individuals are unaware they have it. The symptoms of Alpha-1, such as shortness of breath and wheezing, often overlap with more common conditions like COPD and asthma. This similarity can lead to delayed or missed diagnoses, sometimes taking years for individuals with Alpha-1 to be correctly identified. If you have symptoms or risk factors for Alpha-1, it’s important to discuss testing with your healthcare provider.
Early diagnosis of Alpha-1 is crucial because it allows for timely intervention and treatment. While there is no cure, treatments are available that can help manage the symptoms and potentially slow down lung damage associated with Alpha-1. Furthermore, knowing your Alpha-1 status is important for family planning. Individuals who are carriers of Alpha-1 can determine the risk of passing the gene to their children. A carrier has one normal and one abnormal Alpha-1 gene.
How is Alpha-1 Diagnosed? The Testing Process
Diagnosing Alpha-1 starts with a simple blood test to measure the level of Alpha-1 antitrypsin (AAT) protein in your blood. Lower than normal AAT levels may indicate Alpha-1 Deficiency. If the initial blood test suggests Alpha-1, your doctor might recommend genetic counseling and further testing to confirm the diagnosis and assess the severity of the condition.
Additional tests to evaluate the impact of Alpha-1 may include:
- Lung Imaging: Chest X-rays or CT scans can help assess lung damage.
- Pulmonary Function Tests (PFTs): These tests measure lung capacity and airflow to determine how well your lungs are functioning.
- Liver Ultrasound: This imaging technique can evaluate the health of your liver.
- Liver Biopsy: In some cases, a small liver tissue sample may be taken for closer examination.
Access Free, Confidential Genetic Testing
The Alpha-1 Foundation, in partnership with the University of Florida, offers free and confidential genetic testing through the Alpha-1 Coded Testing (ACT) Study. This convenient at-home test uses a simple fingerstick blood sample. Test results are typically available within 4 to 6 weeks. You can order a free test kit online at Order a free test kit. Please note that ordering requires using a computer or tablet. For more information about the ACT Study, contact the University of Florida at 1-855-476-1227 or [email protected].
Family Matters: Who in Your Family Should Be Tested?
The Alpha-1 Foundation strongly encourages testing for individuals experiencing Alpha-1 symptoms and their family members. This proactive approach is vital for identifying and managing Alpha-1 within families. Recommended family members for testing include:
- Parents
- Siblings
- Children
- Extended family members (aunts, uncles, cousins)
Family members may unknowingly carry Alpha-1 genes, putting them at risk for developing the condition or passing it on to future generations. Knowing their status allows individuals to make informed lifestyle, career, and family planning decisions to protect and improve their health.

Early Alpha-1 antitrypsin diagnosis through simple testing can make a significant difference in managing the condition and protecting your family’s health. Don’t wait, get informed and get tested.
