Hi cwilson1987
Welcome to NeuroTalk

.
Elevated levels of anti-GD1a antibodies are a common diagnostic sign of GBS - you might find this general information about GBS helpful when talking with your doctors;

Acute motor axonal neuropathy is a subclass of GBS. Anti-GD1a antibodies are quite common in it as are antibodies specific for a bacterium (Campylobacter jejuni) - the latter is something that you could get your health care team to check out.
All the best.
