Erythrocyte sedimentation rate is also known as hematocrit, and hematocrit 35 indicates an increase in hematocrit. There are two reasons for hematocrit to increase, one is physiologic increase and the other is pathologic increase. Hematocrit is the distance that red blood cells sink at the end of the first hour to indicate the sedimentation rate of red blood cells. The normal reference value is 0~15mm/1h for men and 0~20mm/1h for women. 1. Physiological acceleration: children and elderly people over 60 years old may have accelerated sedimentation rate, and women may also have accelerated sedimentation rate during menstruation and pregnancy. 2. Pathological acceleration: if you have pneumonia, rheumatoid arthritis and other diseases, the acceleration of blood sedimentation will occur when you have an acute attack. There are many reasons that lead to blood sedimentation rate of 35, if the patient’s symptoms of blood sedimentation rate of 35 or more than the normal value are not relieved, it is recommended to go to the hospital in time for consultation.
