| Test | Viscosity, Serum/ Serum Viscosity |
| Indication | Test is used to evaluate hyperviscosity syndromes associated with monoclonal gammopathy syndromes – myeloma, macroglobulinemia & dysproteinemias, rheumatoid arthritis, systemic lupus erythematosus, hyper-fibrinogenemia. |
| Physiology | Hyperviscosity is the most frequent with IgM monoclonal gammopathy, next with IgA myeloma. In IgG myeloma there is an increase in hyper-viscosity IgG levels. Kappa light chain myeloma is responsible for hyperviscosity syndrome apparently as a result of true polymer formation. |
| Test Method | Viscometer. |
