I recently found some "new" (new to me) info on the binding, blocking, and modulating AChR tests. This article
http://www.kclj.si/ikn/DEJA/Continuu...htoMGorALS.pdf
(Scroll down to page 33)
says that only a positive binding is a "clearcut" diagnosis of MG (???) and that a positive modulating or blocking (in conjunction with a NEGATIVE binding) must be confirmed by some other test such as (?) EMG or SFEMG.
Not sure if I said this right -- and not sure if I can cut and paste -- so, PLEASE click on the link and read for yourself, OK?????
