A tensilon test, also called an edrophonium test, is a pharmacological test used for the diagnosis of certain neural diseases, especially myasthenia gravis.[1] It is also used to distinguish a myasthenic crisis from a cholinergic crisis in individuals undergoing treatment for myasthenia gravis. The test has fallen out of use due to suboptimal sensitivity and specificity as well as associated adverse risks.[2] Edrophonium is no longer available in the United States and many other countries as of 2018.[2]
