Edrophonium Test - Tensilon Test

This test is done to help diagnose myasthenia gravis, a condition in which muscles become tired and weak. In this test, a medication called endorphonium, or tensilon, is given into a vein. Then the responses of certain muscles are evaluated.

Who is a candidate for the test?

The tensilon test is used to confirm the diagnosis of myasthenia gravis. This test is often used to monitor anticholinesterase therapy, a therapy to treat myasthenia gravis.

How is the test performed?

In this test, an intravenous line is placed in a vein. Then the tensilon is given slowly. After a small dose of tensilon has been given, the person is asked to do various exercises to make the muscles tired. Once the muscles are tired, more tensilon is given, and the responses of the muscles to the medication are observed.
