An increased beta or an unusual band between alpha-2 and beta indicates which condition?

• A. Hemolysis (hemoglobin)
• B. Liver failure
• C. Acute pancreatitis
• D. Nephrotic syndrome

Answer: (A)

In serum protein electrophoresis, the pattern of bands reflects which proteins are circulating and in what amounts. An increased beta fraction or a distinct band that appears between the alpha-2 and beta regions points to the presence of a protein that shouldn’t be there in normal amounts in that spot. In a hemolyzed sample, red blood cell contents leak into serum, releasing hemoglobin and its breakdown products. These can migrate to the beta region on electrophoresis, producing an abnormal or extra band in that area. That pattern is a clue that hemolysis has occurred, so the finding best fits a hemolyzed sample.

Liver failure, pancreatitis, and nephrotic syndrome produce different characteristic shifts in the serum protein pattern (such as changes in gamma globulins or albumin loss with compensatory increases), rather than this specific beta-region band.
