    Background: Patients with neuropathy associated with anti-myelin-associated glycoprotein (MAG) antibodies are managed in part by the detection and whenever possible the measurement of IgM-component on serum protein electrophoresis (SPE). Hevylite™ is an immunoassay developed to quantify separately IgMκ and IgMλ and to calculate the IgMκ/IgMλ ratio (HLC ratio). We sought to determine whether HLC ratio can be used to assess diagnosis and to evaluate response to therapy in patients with anti-MAG neuropathy compared to the other currently available tests. Methods: In our tertiary care centre, we retrospectively studied a series of patients with anti-MAG neuropathy. Clinical data and serum samples were collected before treatment and between 6 months and one year maximum after treatment onset. Hevylite™ was performed in a second time after including all patie..
