![]() It would make the assessment of whole blood viscosity costless and the neglect of a known cardiovascular risk factor less excusable.Īssessment chart reference values whole blood viscosity. This article advances a validated method to provide a user-friendly chart that would enable clinicians to assess whole blood viscosity for any patients who has results for full blood count and total proteins. Considering presumptive lower and upper limits, the continuum of ≤14.28, 14.29 - 15.00, 15.01 - 19.01, 19.02 - 19.39 and ≥19.40 (208 Sec(-1)) is obtained as reference ranges for critically low, subnormal low, normal, subnormal high and critically high whole blood viscosity levels respectively. The clinicians' user-friendly chart is presented. After determination of two standard deviations from the mean and ascertainment of symmetric distribution, normal and abnormal reference ranges were defined. For petroleum-based liquids, this covers approximately the range from kerosene to cylinder oils. A chart was formulated so that whole blood viscosity can be extrapolated. The following viscosities are based on materials with a specific gravity of one. This classification defines 20 viscosity grades in the range of 2 to 3200 square millimeters per second (1 mm2/s equals 1 cSt) at 40C (104F). F.2.2 Base oils introduced from other manufacturers shall be tested in accordance with Annex E. Whole blood viscosity at high shear stress was determined, from various possible pairs of haematocrit and total proteins. F-3 December 2016 Version (Reissued 01-04-2017) F.2 Requirements for Passenger Car Motor Oils F.2.1 Blends shall use only base stocks as defined in Annex E. Another objective is to suggest normal, subnormal and critical reference ranges applicable to this method. The objective of this work is to develop an algorithm in the form of a chart by which clinicians can easily extrapolate whole blood viscosity values in their consulting rooms or on the ward. However, a validated arithmetic method exists whereby whole blood viscosity can be extrapolated from haematocrit and total serum proteins. ![]() There are many different methods for the assessment of whole blood viscosity, but not every pathology unit has equipment for any of the methods.
