Plasma is a Newtonian fluid whereby its viscosity is independent of the shear rate it is exposed to. Its normal value at 37°C is around 1.3 mPa s. To put this into perspective, the apparent viscosity of blood at 40% hematocrit and a shear rate of 1,000 s −1 is approximately 5 mPa s with 30% plasma contribution.

Erythrocyte Sedimentation Rate (ESR)
An erythrocyte sedimentation rate (ESR) is a blood test that that can show if you have inflammation in your body. Inflammation is your immune system's response to injury, infection, and many types of conditions, including immune system disorders, certain cancers, and blood disorders. Erythrocytes are red blood cells.
Erythrocyte Sedimentation Rate
The erythrocyte sedimentation rate (sedimentation rate, sed rate, or ESR for short) is a commonly performed hematology test that may indicate and monitor an increase in inflammatory activity within the body caused by one or more conditions such as autoimmune disease, infections, or tumors. The ESR is not specific for any single …

Sed rate (erythrocyte sedimentation rate)
Overview. Sed rate, or erythrocyte sedimentation rate (ESR), is a blood test that can show inflammatory activity in the body. Many health problems can cause a sed rate test result to be outside the standard range. A sed rate test is often used with other tests to help your health care team diagnose or check the progress of an inflammatory disease.
