Blood sedimentation of 23mm/h is not normal, but is a mild increase in blood sedimentation. However, in addition to the speed of the sedimentation itself, whether the sedimentation is normal or not should also be considered as well as whether there are other accompanying symptoms, which should be specifically analyzed. The normal range of hematocrit is 0-15mm/h for adult male and 0-20mm/h for adult female, so hematocrit 23 is not normal. However, hematocrit 23 is a mild increase, which may also be seen in certain physiological conditions, such as children under 10 years old, elderly people over 60 years old, and women during menstruation and pregnancy, etc. A mild increase in hematocrit may occur. The 23mm/h sedimentation rate does not exclude physiological increase, but it also does not exclude pathological increase, such as inflammation and infection, which may cause a mild increase in sedimentation rate. In the early stages of certain malignant tumors, a mild increase in hematocrit may also occur.
