A pattern with decreased albumin, increased α1- and α2-globulins, and normal γ-globulins on protein electrophoresis is most characteristic of which condition?

A pattern with decreased albumin, increased α1- and α2-globulins, and normal γ-globulins on protein electrophoresis is most characteristic of which condition?

• A. Decreased albumin with increased α1- and α2-globulins and normal γ-globulins
• B. Cirrhosis
• C. Nephrotic syndrome
• D. Gammopathy

Answer: (A)

The main idea is how serum protein electrophoresis reflects the liver’s response to inflammation. When inflammation or acute stress occurs, the liver ramps up production of acute-phase proteins that appear in the α1 and α2 regions, while production of albumin (a negative acute-phase protein) drops. Immunoglobulins in the gamma region typically don’t rise in an acute-phase reaction, so the gamma region remains normal. So a pattern with decreased albumin, increased α1- and α2-globulins, and normal γ-globulins directly signals an acute-phase inflammatory state. This makes the described pattern the best match for the underlying physiology, distinguishing it from gammopathy (which elevates γ-globulins) and from liver disease or nephrotic patterns that usually show different gamma or overall changes.
