Since hemoglobin is a vital component of RBCs, its deficiency and malformation lead to low erythrocyte count. Hemoglobin is a protein that transports oxygen to cells and collects carbon dioxide for release through the lungs. Nonetheless, extremely low MCV and MCH can be traced back to problems involving the red blood cells’ hemoglobin. Results from different laboratories may differ slightly. The normal ranges for both are as follows: MCV and MCH are both parameters measured in a complete blood count (CBC) and a peripheral blood smear. When your mean corpuscular volume and mean corpuscular hemoglobin are lower than the healthy range, it may indicate iron-deficiency anemia, microcytosis, and thalassemia. Keep reading to learn more about what to do when you have decreased MCV and MCH. You can improve low MCH and MCV by increasing your dietary intake of foods high in iron, folate, and vitamins A and C. As a result, the number of healthy red blood cells also decreases, leading to anemia.Īlthough anemia is generally not a cause of serious health complications, it becomes a concern when left untreated. To have low MCV and MCH means your hemoglobin production is less than normal. Mean corpuscular hemoglobin (MCV) and mean corpuscular hemoglobin (MCH) go hand-in-hand when diagnosing blood disorders and underlying physiological conditions.
