A decrease in the number or size of red cells also decreases the amount of space they occupy, resulting in lower hematocrit. Similarly an increase in the number or size of red cells increases hematocrit. Exceptions are thalassemia which can cause an increased number of red blood cells but a decreased size and hematocrit, and megaloblastic anemia which causes increase in size of red cells with decreased hematocrit
