Anti-vimentin IgG levels in sera from healthy controls and sarcoidosis patients. The reactivity to human vimentin was determined by ELISA. All sera were tested at 1:100 dilution. Data are plotted as absorbance at 490 nm. Each data point represents one serum sample. The mean O.D. +2SD of the control group was used as a cut-off for positivity and is indicated by the dotted line. The number of patients positive/total for each group is shown in parentheses.
