	Anti-Dopamine Receptor D1; (titer)	Anti-Dopamine Receptor D2L; (titer)	Anti-lysoganglioside GM1 (titer)	Anti-tubulin; (titer)	CaM kinase II (% of baseline)
Patient results	1:8000	1:16,000	1:640	1:4,000	125
Normal Ranges	500-2,000	2,000-8,000	80-320	250-1,000	53-130
Normal Mean	1,056	6,000	147	609	95
