There are many different forms of hemoglobin, the blood component necessary for oxygen transport to the cells and carbon dioxide transport to the lungs for removal from the body. When hemoglobin is placed upon a specialized paper and electricity applied, the different forms of hemoglobin will separate from each other and move along the paper. These bands will be compared to known normal values, which allows for the diagnosis of specific blood diseases. Test results are used to identify sickle cell gene carriers and sickle cell anemia, thalassemia gene carriers and thalassemia, as well as Hemoglobin C, E, and H disease.
