Tensilon test
What do Abnormal Results Mean?
In myasthenia gravis, the muscles will improve immediately following the Tensilon. The maximum benefit only lasts a few minutes. In myasthenic crisis (worsening of the disease that requires anticholinesterase therapy), there is a brief improvement in the muscle strength. In cholinergic crisis (overdose of anticholinesterase), Tensilon will make the person even weaker.
Additional conditions under which the test may be performed include Lambert-Eaton syndrome.
