General Information About the Test
Test Process and Preparation
A low MCH value (Hypochromia) indicates that the amount of hemoglobin inside the red blood cells has decreased, and therefore the cells appear paler in color (hypochromic) than normal. The most common cause is Iron Deficiency Anemia.
MCH is high when red blood cells contain more hemoglobin than normal (and are usually larger in volume). Anemias due to Vitamin B12 or Folic Acid deficiency (Macrocytic anemia) are the primary cause of this.
No. MCH is a mathematical value automatically calculated in the results of the routine Complete Blood Count (Hemogram) test drawn from the arm. It does not require extra blood to be drawn or any preparation.
