The normal value of red blood cells has different ranges for different groups of people, (3.5~5.0)*10^12/L for women, (4~5.5)*10^12/L for men, and (6.0-7.0)*10^12/L for newborns.
Red blood cells are the most numerous type of blood cells in the blood. The production and destruction of red blood cells are basically in dynamic balance, and the quantity and quality of red blood cells in the blood are relatively stable, with normal values varying between males, females, and newborns.
Red blood cells through routine blood tests, red blood cells in the human body plays an important physiological role, such as the body to transport oxygen and carbon dioxide, transport body metabolites, in the immune has a certain role in assisting the white blood cells and lymphocytes, to clear the invasion of pathogens in the body.
A significant decrease or increase in erythrocytes will put the body’s systems and organs in a state of ischemia and hypoxia, leading to a series of clinical symptoms, such as anemia when the erythrocytes decrease, dizziness, headache, fatigue and other symptoms, and when the erythrocytes significantly increase the oxygen-carrying capacity of the patient becomes poor, so the body is in a state of ischemia and hypoxia, with the risk of blood clots.
It is important for the organism to keep the red blood cells in the normal range, and to seek medical attention in case of abnormality.
