Plasma Viscosity or Plasma Viscometry (PV) is the measurement of the viscosity of blood plasma. The end result is a number given in milliPascal seconds (mPa.s) – known as the PV, or plasma viscosity.

Plasma viscosity testing is an easy-to-use, rapid, and stable diagnostic tool for screening and monitoring patients with conditions including rheumatoid arthritis, myeloma, macroglobulinaemia and plasma hyperviscosity.

Interpretation of PV Results

Plasma viscosity is a non-specific screening test used in diagnosing a host of disorders. Here you can find out more information.

ResultsPV range (mPa.s)
Reported at 25ºC
PV range (mPa.s)
Reported at 37ºC
Comments
Normal Range1.50 - 1.721.12 - 1.27
Low results< 1.40< 1.05Found in infants under 3 years old and patients with low immunoglobulin or fibrinogen levels.
High results1.75 - 2.001.30 - 1.46Chronic disorders e.g. infection, malignancy, vascular disease. Autoimmune such as rheumatic diseases.
High results2.01 - 3.001.47 - 2.18Suggestive of Myeloma. IgG-paraproteins. High concentration of asymmetric paraproteins
Extremely high results> 3.00> 2.18Suggestive of Waldenstrom's macroglobulinaemia. Grossly raised IgM-paraproteins.
