The dynamic erythrocyte sedimentation rate, or sedimentation rate for short, is the rate at which red blood cells sink within an hour. Normal dynamic erythrocyte sedimentation rate is 0-15mm/60min for adult men, and 0-20mm/60min for adult women. clinically, the most common cause of dynamic erythrocyte sedimentation rate is the obvious increase in blood sedimentation rate caused by various diseases, including various infectious diseases, rheumatic diseases, tumor diseases and so on. Under certain physiological conditions, the dynamic erythrocyte sedimentation rate can also be increased, such as women’s menstrual period, pregnancy, as well as the elderly over 60 years of age, children under 10 years of age, the erythrocyte sedimentation rate will be mildly increased. Pathological conditions such as severe infections, rheumatic diseases such as rheumatoid, systemic lupus erythematosus, hematologic diseases such as multiple myeloma, and other malignant tumors, can cause a significant increase in erythrocyte sedimentation rate.
