Examination of NMDAR and MOG antibodies in cerebrospinal fluid and serum of our patient. Positive antibodies were confirmed by HEK293 transfected cells via the indirect immunofluorescence method (fixed cell-based assay). MOG-ab uses full-length human MOG to detect MOG-IgG (secondary antibody: IgG Fc). A-D CSF NMDAR and MOG antibodies were positive (titer 1:10 and 1:3.2, respectively) while serum NMDAR and MOG antibodies were positive (titer 1:10 and 1:32, respectively) on day 8. E-L Recheck the antibody on day 168. CSF (E, F) and serum (G, H) NMDAR antibodies were positive (titer 1:1 and 1:10, respectively) while CSF (I, J) and serum (K, L) MOG antibodies were negative and positive (titer 1:10), respectively.
