These are all very relative blood values, they are not absolute values and they have to be judged by the whole blood picture. In the first place there is no need to increase or decrease the MCH once the complete blood picture will improve, the mean corpuscular volume will improve. So go to a doctor and improve the entire blood picture, not just these two values.
