Serum protein electrophoresis

Serum protein electrophoresis (SPEP or SPE) is a laboratory test that examines specific proteins in the blood called globulins. Blood must first be collected, usually into an airtight vial or syringe. Electrophoresis is a laboratory technique in which the blood serum (the fluid portion of the blood after the blood has clotted) is placed into a gel, or into liquid in a capillary tube, and exposed to an electric current to separate the serum protein components into five major fractions by size and electrical charge: serum albumin, alpha-1 globulins, alpha-2 globulins, beta globulins, and gamma globulins.
==Albumin==
Albumin is the major fraction in a normal SPEP. A fall of 30% is necessary before the decrease shows on electrophoresis. Usually a single band is seen. Heterozygous individuals may produce bisalbuminemia - two equally staining bands, the product of two genes. Some variants give rise to a wide band or two bands of unequal intensity but none of these variants is associated with disease. Increased anodic mobility results from the binding of bilirubin, nonesterified fatty acids, penicillin and acetylsalicylic acid, and occasionally from tryptic digestion in acute pancreatitis.
Absence of albumin, known as analbuminaemia, is rare. A decreased level of albumin, however, is common in many diseases, including liver disease, malnutrition, malabsorption, protein-losing nephropathy and enteropathy.
