Hi Spud,
Not everyone with MMN has the antibodies the blood tests are designed to detect so a negative blood test does not rule out MMN, hence the lumbar puncture / spinal tap test.
I am glad your mother is getting a 2nd opinion - MMN should have different NCS & EMG results than ALS.
Best to you both.
Love Ellie.
