The normal value of blood sedimentation is (2~10) mm/h for men and (3~15) mm/h for women. 88 mm/h of blood sedimentation is greater than the normal value, but only by virtue of the blood sedimentation, it is not possible to directly determine the severity of the disease. Blood sedimentation, i.e. erythrocyte sedimentation rate, refers to the rate of red blood cells settling in the plasma under certain conditions. Under normal conditions, the surface of red blood cells is negatively charged, mutually exclusive, dispersed and suspended in the plasma, with relative suspension stability, the settlement is extremely slow. When the plasma macromolecular proteins, such as fibrinogen, globulin, etc. increase, the negative charge on the surface of the erythrocyte membrane decreases, electrostatic repulsion decreases, resulting in erythrocytes are easy to form a string of coins or aggregation, so that the erythrocyte sedimentation rate accelerated. Increased sedimentation rate can be physiologic or pathologic. Physiologic increases are common in children under 12 years of age and in menstruating and pregnant women. Pathological increase is seen in various acute inflammation, tissue injury and necrosis, malignant tumors, and relative or absolute increase of plasma globulin caused by various reasons. When the blood sedimentation increases, please consult the doctor in time for further examination to clarify the cause, if it is not physiological increase, please actively carry out targeted treatment under the guidance of the doctor to avoid delaying the course of the disease.
