Myasthenia gravis: The test is negative based on the normal reference values for that laboratory used. I wonder if modulating ab, anti-musk and anti skeletal muscles antibodies should be checked. If you have an objective measurable weakness an edrophonium test, or repetitive nerve stimulation can be performed and may be useful in the diagnosis. A single fiber EMG is another diagnostic tool available.
