Is it harmful to the body to draw blood often after liver function examination?

Regular blood sampling for liver function review will not affect your health, so don't worry. The total blood volume of an adult is generally 4000 ~ 5000 ml, and the blood contains many components which are metabolized in the body, such as the survival time of red blood cells 120 days, white blood cells10 ~/2 hours and platelets/9 ~1day. New blood cells will continue to develop from the bone marrow. So each person is allowed to draw blood within 400 ml at a time. Only about 10 ml of blood was taken in the test, which will not affect the metabolism and defense function of the body at all. According to related reports, pumping a small amount of blood often is good for stimulating bone marrow hematopoiesis. Therefore, in order to dynamically observe the changes of liver function, taking a small amount of blood regularly to review liver function will not affect health.
