Why this matters
MCH levels can reveal early changes in red blood cell health before obvious symptoms like fatigue or weakness appear. Low MCH often points to iron deficiency or anemia, while high MCH may indicate vitamin B12 or folate deficiency or certain liver conditions. Maintaining a balanced diet with adequate iron, B12, and folate, along with regular checkups, helps support healthy red blood cells and oxygen delivery throughout the body.
