Clinical Significance

Evaluate hyperviscosity syndrome associated with monoclonal gammopathy states (myeloma, macroglobulinemia of Waldenström, and other dysproteinemias), including occasional cases of rheumatoid arthritis, SLE, systemic lupus erythematosus, hyperfibrinogenemia.

Hyperviscosity syndrome is associated with dysproteinemias, such as multiple myeloma and Waldenstrom's macroglobulinemia, and RBC disorders, such as polycythemia and sickle cell anemia.Neonatal hyperviscosity can occur in susceptible neonates, such as those subjected to intrauterine hypoxia, and infants of diabetic mothers. Other factors contributing to polycythemia are delayed clamping of the umbilical cord (placental transfusion), twin-to-twin transfusion, and maternal-fetal transfusion.Increased viscosity may also play a part in the pathogenesis of coronary heart disease, thrombosis, arteriosclerosis, some types of hypertension, diabetes, and even trauma. Increased viscosity is possibly the "final common pathway," through which many diseases produce symptoms, tissue damage, and ultimately death.
