• Anaemia is the condition in which the capacity of the blood to carry oxygen is reduced. It can be due to either a decreased amount of hemoglobin or a decreased number of RBCs.
• Polycythaemia is the condition when RBC count is abnormally high. It happens in bone marrow diseases. Blood becomes thick and can clot easily.
• Erythrocytopenia is the condition when RBC count is low. It can cause anaemia.
