What is MCV in the blood test?

MCV parameter in blood test
This parameter is the red blood cell volume and is calculated in terms of the femtoliter femtoliter. In order to be able to correctly interpret this parameter, we need to know its changes in different periods of life. At birth, the amount is 103 to 118, then this parameter decreases as the baby grows and reaches its minimum at one year and reaches 78 ± 8.

MCV stands for MEAN CORPOSCULAR VOLUME, with a normal range of 80 to 96 ft. If it falls below this level, the red blood cell is smaller in size than the normal or normal level, called microcyte, and one of the reasons is to reduce hemoglobin. If this number is increased, the size of the red blood cell is greater than normal, which is due to increased hemoglobin. Changes in this amount in the body, cause symptoms that the doctor can make the final conclusions.

Interpretation of the parameter mcv in the blood test
The natural rate is 80-96 femtolite or fl. How to measure MCV is that hematological devices measure the size of a large number of RBCs and calculate their average. To interpret the amount of MCV, we can place red blood cells in volume in three groups of Normocyte, Microcyte and Macrocyte. RBCs range from 96-80 = Normocyte, over 100 macrocytes and below 80 microsites.

Note: We must know that the blood parameters are constant in each person and that its changes should not exceed 1 ±. For example, if the individual MCV is 85, with multiple tests, it should be between 86-84 fl, and if it is supposed to be 75, then everything should be re-examined. Using the formula DF 1 and Mentzen index in the office, MCV can be used to detect iron deficiency from thalassemia. If DF was negative thalassemia and if positive was a sign of iron deficiency. Notice the following formula:

DF = MCV - RBC - (5 × Hb) - 3.4


If MI is below 13, thalassemia and if it is above 13, it is iron deficiency. The MCV shows us the size of the RBC; that is, if the individual MCV, for example, is 80, has a small, large, or normal RBC; however, what factor can show us how small or large RBCs are, this factor RDW is named.
