Plasma viscosity: understanding testing, reference ranges and clinical applications
20 Oct 2026This application note explains the principles and clinical value of plasma viscosity (PV) testing as a marker of inflammation and disease activity. Discover how plasma viscosity reflects changes in plasma proteins associated with infection, inflammation, and traumatic injury, and why it can offer advantages over ESR and CRP testing in certain clinical settings. Explore common applications in conditions such as multiple myeloma, Waldenström’s macroglobulinemia, hyperviscosity syndrome, and rheumatoid arthritis, along with guidance on reference ranges, result interpretation and rapid laboratory turnaround times.
