Can you tell me if a patient with severe anemia of 3.5 hb count and bed ridden can't go to hospital can have blood transfusion at his home?

Difficult to do. Giving transfusion requires to have the procedure monitored closely as severe reactions,. There is also concerns about transporting blood products and having appropriate personnel to monitor. If the blood count is that low the patient needs to be evaluated to determine the cause of her anemia also.
