WebMay 23, 2024 · A, A close correlation was found between cerebrospinal fluid (CSF) and serum SARS-CoV-2 nucleocapsid antigen. Individual points are shown using unadjusted nucleocapsid antigen concentrations in patients with COVID-19. The median (IQR) ratio of serum-CSF nucleocapsid antigen was 42 (range, 18-89). WebThe IgG index equal to CSF/serum IgG:CSF/serum albumin is elevated in about 70% of MS patients, but rarely in CSF OB-negative MS. Because of lower diagnostic sensitivity, IgG index cannot be recommended as replacement of CSF OB in the diagnosis of MS but, when elevated, as additional evidence for an augmented B-cell response within the CNS that ...
