Mean Corpuscular Volume Calculator or MCV Calculator estimates the average size of the erythrocytes in a blood sample based on hematocrit and RBC count.


MCV Calculator

  • This mean corpuscular volume (MCV) calculator determines the average size of the erythrocytes in a complete blood count to diagnose anemia and belong to the RBC indices.
  • You can read more about the formula, the normal range and what types of anemia occur when MCV is elevated or lower than normal.


Mean Corpuscular Volume Meaning

  • The mean corpuscular volume (MCV) is one of the three Red Blood Cell (RBC) indices and considered to be the most important because of the involvement in anemia diagnosis and determination of Red Blood Cell Distribution Width (RDW).
  • It is typically measured as part of a complete blood count (CBC) test, which is a routine blood test used to evaluate a person's overall health.
  • The MCV measurement is reported in femtoliters (fL) and represents the volume of an average RBC.
  • A high MCV value indicates that the RBCs are larger than normal, while a low MCV value indicates that the RBCs are smaller than normal.


How To Calculate Mean Corpuscular Volume

  1. Enter the Hematocrit value (as a percentage): Hematocrit (%):
  2. Enter the Red Blood Cell Count (million cells/mcL)
  3. Calcute the MCV value.


Mean Corpuscular Volume Calculator Formula

This erythrocyte parameter can be measured through automated hematology analysis or estimated via the following equation:

MCV in fL = (Hematocrit %) / (RBC million cells/mcL) x 10


Mean Corpuscular Volume Parameter Normal Value

The normal values for hematocrit, RBC and MCV can be found in the table below:

Parameter Normal range
Hematocrit 37 – 52%
RBC 4.2 – 6.3 million cells/mcL
MCV 80 – 96 fL


Mean Corpuscular Volume Normal Range

The normal range for Mean Corpuscular Volume (MCV) is typically between 80 and 100 femtoliters (fL). However, the specific normal range may vary slightly depending on the laboratory and testing methods used.


Mean Corpuscular Volume Normal Range


Here is a table with the normal MCV ranges:

Age Group MCV Range (fL)
Adult men 80-100
Adult women 80-100
Children 70-86
Newborns 95-121

It's important to note that a normal MCV range doesn't necessarily rule out the presence of a medical condition, and other factors such as age, gender, and health status can also affect the MCV result. It's best to discuss any abnormal MCV results with a healthcare provider.


Mean Corpuscular Volume Interpretation

Here is a table that provides a general interpretation of Mean Corpuscular Volume (MCV) results:

MCV Range (fL) Interpretation
< 80 Microcytic anemia, which can be caused by iron deficiency or thalassemia
80-100 Normal range
> 100 Macrocytic anemia, which can be caused by vitamin B12 or folate deficiency, alcohol abuse, or other conditions


Increased MCV

  • MCV values that are higher than normal mean that erythrocytes are enlarged. This is suggestive of Macrocytic or pernicious anemia.


An increased Mean Corpuscular Volume (MCV) value can be indicative of several medical conditions, including:

  • Vitamin B12 or folate deficiency anemia
  • Alcohol abuse
  • Liver disease
  • Hypothyroidism
  • Hemolytic anemia


Decreased MCV

  • When MCV values are lower than normal (going as low as 60 fL, when normal low is around 80 fL), the red blood cells are likely to be smaller than average.


A decreased Mean Corpuscular Volume (MCV) value can be indicative of several medical conditions, including:

  • Iron-deficiency anemia
  • Thalassemia
  • Chronic diseases:
  • Lead poisoning
  • Hemorrhage


Mean Corpuscular Volume Calculator Benefits

There are several benefits to using a Mean Corpuscular Volume (MCV) calculator. These include:

  1. Accurate calculations: A MCV calculator can accurately calculate the MCV value based on the Hematocrit and Red Blood Cell Count values, eliminating the risk of manual calculation errors.
  2. Easy and convenient: Calculating the MCV manually can be time-consuming and requires specific knowledge and formulas. A MCV calculator simplifies the process and makes it easier and more convenient to obtain accurate results.
  3. Quick interpretation: A MCV calculator can provide a quick interpretation of the MCV value, indicating whether it falls within the normal range or is indicative of anemia.
  4. Monitoring changes over time: A MCV calculator can be used to monitor changes in MCV over time, which can help healthcare providers track the progression of anemia and adjust treatment accordingly.



Overall, using a MCV calculator can improve the accuracy, speed, and convenience of MCV calculations, leading to better monitoring and treatment of anemia and related conditions. Check More Medical Health Related Calculator on Drlogy Calculator to get exact health solution.

Mean Corpuscular Volume Calculator FAQ

What happens if MCV is low?

  • If MCV is low, it means that the average size of the red blood cells in the blood is smaller than normal.
  • This condition is known as macrocytosis.
  • Microcytosis can be caused by a variety of conditions such as iron-deficiency anemia, thalassemia, lead poisoning, or chronic disease.

Does high MCV mean liver disease?

High MCV alone does not necessarily mean liver disease.

  • However, certain liver diseases such as cirrhosis or alcohol-related liver disease can lead to macrocytosis (high MCV).
  • It's important to consult with a healthcare professional to determine the underlying cause of macrocytosis, as there are many potential causes, and a comprehensive evaluation is required to identify the correct diagnosis.

What is the normal range for MCV calculated?

The normal range for MCV (Mean Corpuscular Volume) is 80-100 femtoliters (fL), which represents the average volume of a single red blood cell.

  • MCV is calculated by dividing the total volume of red blood cells by the number of red blood cells in the blood, as measured by a laboratory test called a complete blood count (CBC).
