ReferencesĬhandler WL and Schmer G, Evaluation of a new dynamic viscometer for measuring the viscosity of whole blood and plasma, Clin Chem (1986) 32:505. Hyperviscosity syndrome can also occur in multiple myeloma patients, and, rarely, in patients with rheumatoid factors and other aggregating proteins. The most common cause of serum hyperviscosity is the presence of large concentrations of IgM monoclonal proteins, and Waldenstrom's macroglobulinemia accounts for 80% to 90% of symptomatic hyperviscosity cases. Please provide SERVICE AREA INFORMATION to find available tests you can order. Although viscosities >1.6 are abnormal, hyperviscosity syndromes are rarely present unless the relative viscosity is >4.0 (approximately). Viscosity, Serum - High serum viscosity may be most commonly observed in. The value of these tests is limited by lack of specificity. infection, neoplasm or inflammatory disease). the increase in assorted plasma proteins and fibrinogen in blood plasma stimulated by a variety of causes (e.g. ![]() Results are reported as a relative viscosity to water, where normal serum and plasma have a relative viscosity of up to 1.6. The Plasma Viscosity, alongside the ESR and C-Reactive Protein tests, gives a measure of the acute phase response i.e. Serum, plasma or whole blood viscosity measurements can be useful in patients with hyperviscosity syndromes due to multiple myeloma or Waldenstrom's macroglobulinemia. Viscosity is the property of fluids to resist flow. ![]() Lab Name Viscosity, Serum Lab Code SRVISG Epic Ordering
