Normal red blood cell count for men

I often felt dizzy for a while. My eyes were dark when I stood up after squatting down. So I went to have a blood test to check my blood routine. After getting the report, I quickly looked at my blood cell count, white blood cell count, platelet count, scarlet platelet count and other key indicators that reflect the blood composition to see if they were within the standard value. Each indicator value usually has a range, so what is the standard value of men's blood cells?

How much is the blood cell standard worth?

Men: 3.8-6 million/mm3; normal index: 4.0-5.5X1012 cubed/liter. Women: 3.8-5.5 million/mm3; normal index: 3.5-5.0X1012 cubed/liter. Blood cells are very small, with 5 million blood cells in 1 cubic millimeter of blood, and the number of blood cells in the human body reaches 25 billion. The number of red blood cells may vary to a certain extent with different external conditions and age. Residents in plateau areas and newborns reach more than 6 million/mm3. People who participate in sports competitions or exercise regularly also have more blood cells. The hemoglobin concentration component is 12-15g/100ml for men and 11-13g/100ml for women.

What causes blood cells to deviate from standard values?

1. Erythrocytosis: The absolute increase in the concentration of blood cells and hemoglobin in the blood is caused by various reasons, most of which are related to factors such as insufficient oxygen in the body's circulatory system and tissues, increased levels of hemopoietin in the blood, and accelerated release of blood cells from the bone marrow. Physiological reasons for high red blood cell counts: In addition, drinking too little water or sweating too much, excreting too much water, etc. can also cause high red blood cell counts.

2. Reduced blood cell conversion: various chronic diseases such as aplastic anemia, sepsis, myeloma, myelofibrosis, etc. cause long-term consumption of the body, such as malignant tumors, uremia, liver disease, rheumatism, endocrine diseases, etc.; diseases caused by deficiency or obstruction of hematopoietic functional substances, such as iron deficiency anemia, megaloblastic anemia caused by folic acid or vitamin B212 deficiency.

Knowing the normal range of blood cells, the next time you look at the test report, it will be clear. Blood cells are the main components of transporting oxygen. Slightly low or high values ​​will cause fluctuating effects on the human body, especially for children in the growth period. Once you feel unwell, you must go to the hospital for a routine blood test in time to ensure that the blood cells are within the normal range so that they can grow healthily.
