Alpha-1 Globulin is a fraction of serum proteins identified during electrophoresis. It primarily consists of Alpha-1 Antitrypsin (AAT), an acute-phase reactant. This fraction increases during systemic inflammation, infection, or trauma. A decrease in this fraction is a critical screening marker for Alpha-1 Antitrypsin Deficiency, which can lead to early-onset emphysema and liver cirrhosis.

Why Context Matters

Because Alpha-1 globulin is an acute-phase reactant, a 'normal' level might actually mask an underlying deficiency if the patient has concurrent inflammation. Phenotyping or genotyping may be required for a definitive diagnosis if levels are borderline.

Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
