Anemia is graded primarily by the degree of decrease in hemoglobin in the blood.
Anemia is a class of clinical syndromes in which the volume of red blood cells in the peripheral blood of the human body decreases below the lower limit of the normal range and fails to adequately supply oxygen to tissues and organs. It is mainly based on the degree of decline in hemoglobin in the blood to classify anemia into 4 grades: mild, moderate, severe and very severe.
The severity of anemia is related to the hemoglobin value, and also to the rate of hemoglobin decline. Mild anemia is hemoglobin 90 to 120 g/L, moderate anemia is hemoglobin 60 to 90 g/L, severe is hemoglobin 30 to 60 g/L, and very severe is hemoglobin less than 30 g/L.
