Hard to say: Certainly, the negative EMG is a good sign. Als can sometimes be elusive early on and it comes in different forms- some more rapidly progressive than others. The negative imaging is not important other than to exclude other causes of the weakness. In your case, there is no substitute for time and in the very unlikely event that it is als, it will be more evident later on.

ALS: That's great news that the EMG was negative with respect to detecting anything serious related to your symptom of weakness. Just to help clarify that neither bloodwork, mri, or mra will help rule in or rule out als. But it is excellent news that the EMG and ncv's were negative in this case. Best to you. Stay in touch with your dr. Though if anything changes as they may wish to retest you.

Yes: Based on the information provided, yes ALS appears to be off the table.

Yes, for now: There are many causes of weakness and if all the tests were done properly and are negative, you could say that ALS is off the table. You should keep searching for the possible causes.
