Electrophoresis
Electrophoresis: A method used in clinical and research laboratories for separating molecules according to their size and electrical charge. An electric current is passed through a medium that contains the mixture of molecules. Each kind of molecule travels through the medium at a different rate, depending on its electrical charge and molecular size. Separation of the molecules occurs based on these differences.

- Electrophysiologic retinal testing
Electrophysiologic retinal testing: Testing done to diagnose specific disorders of the retina, including inherited retinal diseases, the effects of toxic drug exposure on the retina, and the presence of foreign bodies within the eye. The most commonly performed electrophysiologic test is the electroretinogram (ERG). Other electrophysiologic tests include electro-oculography (EOG), visual evoked response (VER), dark […]

Electrophysiologic study of the heart: A test of the electrical conduction system of the heart (the system that generates the heart beat). Electrophysiologic study (EPS) of the heart is done by threading thin plastic tubes (catheters) into a vein where the leg connects to the abdomen. A local anesthetic is given as well as a […]
