The normal mean corpuscular volume (abbreviated to MCV on full blood count results, and also known as mean cell volume) is approximately 80–100 fL. When the MCV is <80 fL, the red cells are described as microcytic and when >100 fL, macrocytic (the latter occurs in macrocytic anemia). The MCV is the average red blood cell size.
MCHC can be normal even when hemoglobin production is decreased (such as in iron deficiency) due to a calculation artifact. MCHC can be elevated ("hyperchromic") in hereditary spherocytosis, sickle cell disease and homozygous hemoglobin C disease, depending upon the hemocytometer. [4] [5] MCHC can be elevated in some megaloblastic anemias. MCHC ...
Normally, MCV is expressed in femtoliters (fL, or 10 −15 L), and [RBC] in millions per microliter (10 6 / μL). The normal range for MCV is 80–100 fL. If the hematocrit is expressed as a percentage, the red blood cell concentration as millions per microliter, and the MCV in femtoliters, the formula becomes
The mean corpuscular hemoglobin, or "mean cell hemoglobin" (MCH), is the average mass of hemoglobin (Hb) per red blood cell (RBC) in a sample of blood. It is reported as part of a standard complete blood count. MCH value is diminished in hypochromic anemias. [1] RBCs are either normochromic or hypochromic. They are never "hyperchromic".
The MCH and MCHC can be confusing; in essence the MCH is a measure of the average amount of hemoglobin per red blood cell. The MCHC gives the average proportion of the cell that is hemoglobin. The MCH does not take into account the size of the red blood cells whereas the MCHC does. [116] Collectively, the MCV, MCH, and MCHC are referred to as ...
Supportive blood work: Mean cell volume (MCV): Normocytic (normal range: 80–100 fL), or slightly lower. Spherocytes are slightly smaller than normal biconcave red blood cells. Mean corpuscular hemoglobin concentration (MCHC): Increased (normal range: 31–36% Hb/cell). This is secondary to less water being in the cell.
The blood film can point towards vitamin deficiency: Decreased red blood cell (RBC) count and hemoglobin levels [7] Increased mean corpuscular volume (MCV, >100 fL) and mean corpuscular hemoglobin (MCH) Normal mean corpuscular hemoglobin concentration (MCHC, 32–36 g/dL)
The normochromic cells have a normal concentration of haemoglobin, and are therefore 'red enough' while the hypochromic cells do not; thus the value of the mean corpuscular hemoglobin concentration.The most common cause of microcytosis is iron deficiency anemia. Every time Hb synthesis being impaired in bone marrow microcytosis can occurs such ...
