WebIn regenerative anaemias there is an increased loss of red cells from the circulation, caused by either haemorrhage or haemolysis. a) Haemorrhage In the immediate aftermath of an episode of haemorrhage the PCV will be normal due to loss of whole blood, anaemia occurs when circulatory volume recovers and red cell numbers remain low.
