MCV measures red blood cell size and volume. Normal MCV levels are 80 to 100 fl, but they may vary by age and sex. Low or high MCV levels indicate different types of anemia, such as iron deficiency or vitamin B12 deficiency. A mean corpuscular volume (MCV) test measures the average size and volume of red blood cells. Low, high, or normal MCV can indicate types of anemia. The MCV blood test is a vital tool for assessing red blood cell size, which can reveal anemia, nutritional deficiencies, or other health conditions. The MCV blood test normal range is 80–100 fL, with deviations pointing to microcytosis (low MCV ) or macrocytosis (high MCV ). The MCV blood test measures the Mean Corpuscular Volume ( MCV ), which shows the average size of red blood cells. It is an important part of the complete blood count and helps detect problems such as anemia, bleeding, hypothyroidism, or chronic infections. Normal MCV values are usually between 80 and 100 fL, although the exact range may vary slightly by laboratory. Results outside this range can indicate conditions like iron deficiency anemia, megaloblastic anemia, or thalassemia.
