What is the normal Mean Corpuscular Volume (MCV) range denoting the size of red blood cells (RBCs)?

70-80 fL

80-100 fL

The normal range for Mean Corpuscular Volume (MCV), which reflects the average volume of red blood cells (RBCs), is between 80 and 100 femtoliters (fL). This measurement is crucial in evaluating red blood cell characteristics, aiding in the diagnosis of various types of anemia and other hematological conditions.

Values within this range indicate that red blood cells are of adequate size, which is essential for effective oxygen transportation throughout the body. When MCV falls below this range, it suggests microcytic anemia, while values above it can indicate macrocytic anemia. Thus, understanding the normal MCV range is important for assessing a patient's hematological status and guiding further diagnostic and therapeutic interventions.
