Thanks so much for your comments; I really appreciate. Actually the normal PCV level is 38% , but with Crisis it comes to as low as 16% but after transfusion it return back to normal. Unfortunately this time around it is not the same; when the crisis started the PCV level was 10% with blood transfusion it rises to 22% after 2days it return back to 13% another blood was transfused it rises to 26% after 2days again it reduce to 10% hence my predicament; What is draining the blood and what is the solution?
