-
Direct measurement of electrolytes
Measurement of serum-plasma ions, such as sodium, chloride, and potassium, without prior dilution of the sample. Direct measurement of electrolytes is considered more physiologically accurate than indirect measurement.
-
Electroimmunodiffusion
A laboratory method of identifying antigens in the blood by creating an artificial antigen-antibody reaction.
-
Electrohydraulic
To the electrical generation of shock waves in a fluid; said of a device or system.
-
Electrogoniometer
An electrical device for measuring angles of joints and their range of motion.
-
Electroencephalographic technologist
A technologist who operates and maintains electroencephalographic machines.
-
Electroencephalograh
An instrument for recording the electrical activity of the brain.
-
Electroejaculation
The retrieval of semen by electrical stimulation of the prostate. Electroejaculation is used to obtain sperm from men who are unable to ejaculate, e.g., because of spinal cord in jury. It has also been used in veterinary medicine.
-
Electrodynamometer
An instrument that measures the strength of an electric current. A device that measures both the voltage and amperage of alternating current.
-
Electrodialysis
A method of separating electrolytes from colloids by passing a current through a solution containing both. A semipermeable membrane is usually used to aid in the separation, with one electrode on each side.
-
Electrodiagnostic technologist
A specialist in the use of neurological diagnostic devices, including electroencephalography, electromyography, polysomnography, and evoked potentials.
