Subclass-based ANA test in IgG4-RD, showing immunofluorescence microscopy of two typical IgG4-RD cases (IgG4-RD #3 and #5). Lower right panel: We confirmed the second antibody’s function by direct immunofluorescence of a lymph node specimen (IgG4+/IgG+ plasma cell ratio = 0.69) from an IgG4-RD patient (IgG4-RD #14).
