title: The hyperviscosity syndrome in an IgA-2 myeloma patient.
abstract: We have compared serum viscosities in 2 patients with the IgA type of multiple myeloma. One patient had the rare condition of IgA-2 myeloma. We confirm that hyperviscosity is associated with higher polymers. It would appear that there is no barrier to polymer formation with the IgA-2 subclass.
