title: Serum viscosity and hyperviscosity syndrome in IGG multiple myeloma - the relationship of Sia test and to concentration of M component.
abstract: The Sia test has been used for a long time for the diagnosis of macroglobulinemia, but its significance in myeloma is not known. It has recently been reported that the majority of sera in immunoglobulin G (IgG) myeloma with hyperviscosity syndrome are Sia-positive.
