How accurate are nerve conduction studies in detecting Myasthenia Gravis?

Nerve conduction studies (NCS) are helpful in evaluating nerve function and can aid in the diagnosis of Myasthenia Gravis (MG). However, it is important to note that NCS alone may not provide a definitive diagnosis for MG. While NCS can detect abnormalities in nerve conduction, such as slowed or blocked signals, it may not directly assess the underlying cause of muscle weakness related to MG.
