Normal blood indicators are the normal range of various blood cells in the peripheral blood. Normal blood indicators include three major categories: white blood cell indicators, red blood cell indicators, and platelet indicators. The first indicator is white blood cell indicator, including the number of white blood cells, the normal adult blood contains 4,000-10,000 white blood cells per milliliter, while neutrophils account for 50%-70% of all white blood cells, lymphocytes account for 20%-40% of all cells, monocytes account for 3%-8% of all cells, eosinophils account for 0.5%-5% of all cells, basophils accounts for 0-1% of all cells. The second index is the red blood cell index which includes the number of red blood cells and hemoglobin concentration. The number of red blood cells contains 4-5.5 million red blood cells per milliliter in adult males and 3.5-5 million red blood cells per milliliter in adult females. The hemoglobin concentration is 120-160 g/L for adult males and 110-150 g/L for adult females. the third indicator is the platelet indicator, which contains 100,000-300,000 platelets per milliliter of blood in normal people.
