Takeaway
Due to discrepancies between reported symptoms and serological results, along with the high rate of co-infections, broad serological testing is important to help identify the most likely infectious triggers in patients with Guillain-Barré syndrome (GBS).
Why this matters
The clinical features and disease severity of GBS varies across geographical regions, which may be due to differences in the distribution of preceding infections.
By studying differences in the distribution of preceding infections prior to GBS development, the clinical course and long-term prognosis of patients with GBS may be determined.
