Recommendations for Initial Testing for Suspected AFM

Specimen	Tests
Respiratory (nasopharyngeal swab)	Respiratory virus PCR panel, enteroviral PCR
Serum	Enteroviral PCR, NMO (aquaporin 4), and MOG antibody testing, consider Lyme and West Nile antibody testing when clinically appropriate
CSF	Basic studies, enteroviral PCR testing
Stool	Enteroviral PCR
Imaging	MRI of the spinal cord with and without contrast, strongly consider MRI brain with and without contrast
