What is a Tensilon challenge test?
A Tensilon test is a diagnostic test used to evaluate myasthenia gravis, which is a neuromuscular condition characterized by muscle weakness. The test involves an injection of Tensilon (edrophonium), after which your muscle strength is evaluated to determine whether your weakness is caused by myasthenia gravis or not.
Why is edrophonium used in diagnosis of myasthenia gravis?
Edrophonium is a rapid-acting anticholinesterase drug of short duration that improves symptoms of myasthenia gravis by inhibiting the breakdown of ACh and increasing its concentration in the neuromuscular junction.
What amount of edrophonium is given in Edrophonium test?
A 2-mg (0.2-mL) test dose of edrophonium is administered because some patients are extremely sensitive to even low dosages. If there is no improvement after 30 seconds, the remaining 8 mg is administered in small increments (2 mg every 15 seconds).
What do you need for a tensilon test?
Procedure. A 10 mg edrophonium chloride syringe and a 2 mg atropine syringe are prepared. Atropine is prepared for immediate use in case cholinergic crisis occurs. After a neurologic examination and recording of vital signs, 2 mg edrophonium is injected intravenously.
What is tensilon test used for?

What is a tensilon crisis?
A tensilon test, also called a edrophonium test, is a pharmacological test used for the diagnosis of certain neural diseases, especially myasthenia gravis. It is also used to distinguish a myasthenic crisis from a cholinergic crisis in individuals undergoing treatment for myasthenia gravis.
What is the purpose of the Tensilon test?
The Tensilon test is a pharmacological challenge study performed to assist in the diagnosis of myasthenia gravis. The drug used in edrophonium chloride (Tensilon), a short-acting form of the drug used to treat this disorder.

The test may also be done for conditions such as Lambert-Eaton syndrome. This is a disorder in which faulty communication between nerves and muscles leads to muscle weakness. In many people with myasthenia gravis, the muscle weakness will improve right after receiving Tensilon.
What kind of machines are used for tensile testing?
ASTM, ISO, EN, IDN and JIS are some of the standardized products used in tensile test machines. When choosing a specimen, take note of the shape, size and dimensions, as well as the grips at the ends. These are important factors to consider before performing tensile testing.
