MCV Test

What is MCV?

• Definition: MCV measures the average volume of red blood cells, typically expressed in femtoliters (fL, which is equal to 10^-15 liters) per cell.
• Function: It helps classify anemia and other conditions based on the size of red blood cells.

Why is MCV Important?

• Anemia Classification: Helps differentiate between different types of anemia based on red blood cell size.
• Diagnostic Tool: Provides information about red blood cell morphology and can indicate underlying health conditions affecting red blood cell production.

When is MCV Measured?

• Complete Blood Count (CBC): MCV is routinely measured as part of a CBC, along with other parameters such as hemoglobin, hematocrit, and red blood cell count.
• Anemia Evaluation: Specifically used to assess red blood cell size and classify anemia as microcytic, normocytic, or macrocytic.
