A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the tourniquet is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding . Cotton or a bandage may be applied to the puncture site if there is any continued bleeding.
Immunoelectrophoresis is a laboratory technique.
Protein electrophoresis indicates immunoglobulins as a group. Immunoelectrophoresis enhances the ability to identify the specific immunoglobulins through the use of specific antibodies to the proteins of interest. The presence of a precipitin band indicates that the antigen is present for the monospecific antiserum used.
