High Alpha-1-antitrypsin: what it means
A Alpha-1-antitrypsin result above the normal range is considered high. Here is what a raised Alpha-1-antitrypsin can point to, and when it is worth discussing with a doctor.
Reference range: ~1.0–2.0 g/L; a protective protein made by the liver — a LOW level (alpha-1-antitrypsin deficiency) can cause early lung disease (emphysema) and liver disease
Understand your full resultWhat a high Alpha-1-antitrypsin can mean
- Inflammation or infection — it is an acute-phase protein, so the level rises with these; usually not significant in itself.
- A normal or high level makes a deficiency unlikely — reassuring when the deficiency is the question.
When to discuss with a doctor
Alpha-1-antitrypsin is worth checking in specific situations: emphysema or COPD developing at a younger age or in someone who has never smoked, unexplained chronic liver disease, or a family history of the deficiency. A low level is followed by confirmatory genetic testing to establish the diagnosis. Diagnosis matters because avoiding smoking (and other lung irritants) is the single most important step to protect the lungs, and both the lungs and liver can then be monitored and managed, with specific treatments available in some cases. Because the level rises with inflammation, a borderline result may be repeated when well. Mediora.AI can highlight a low alpha-1-antitrypsin alongside liver markers so the pattern is visible, but confirming and managing the deficiency belongs with your doctor and, usually, a specialist.
