Why does ESR increase during pregnancy? Quora
The erythrocyte sedimentation rate (ESR) is the rate at which red blood cells sediment in a period of one hour. It is governed by the balance between pro-sedimentation factors, mainly fibrinogen, and those factors resisting sedimentation, namely the negative charge of the erythrocytes (zeta potential).

The erythrocyte sedimentation rate (ESR or sed rate) is the rate at which red blood cells sediment in a period of one hour. It is a common hematology test, and is a non-specific measure of inflammation .
Erythrocyte sedimentation rate (ESR) and hematocrit (HCT)
1) Determination of erythrocyte sedimentation rate (ESR). 2) Determination of hematocrit (HCT). 3) To assess the condition of a patient by such tests.
ERYTHROCYTE SEDIMENTATION RATE Cancer Screening UK
The sedimentation rate is directly proportional to the weight of the cell aggregate and inversely proportional to the surface area. Microcytes sediment slower than macrocytes, which have decreased surface area/volume ratios. Rouleaux also have a decreased surface area/volume ratio and accelerate the ESR.

Test ESR--Erythrocyte Sedimentation Rate The ESR measures the time required for erythrocytes from a whole blood sample to settle to the bottom of a vertical tube. Factors influencing the ESR include red cell volume, surface area, density, aggregation, and surface charge.
