Hemoglobin is a protein in your red blood cells that carries oxygen from your lungs to the rest of your body. There are several types of hemoglobin. Hemoglobin electrophoresis is a test that measures the different types and identifies abnormalities.
Serum protein electrophoresis (SPE) is an analytical technique that separates serum protein into six fractions: albumin, alpha-1, alpha-2, beta-1, beta-2, and gamma. Interpreting elevation, decrease, or visual change in different fractions can diagnose various disease states and protein abnormalities.
