What is MCV MCH and RDW?
The RBC indices are comprised of four different components known as the mean corpuscular hemoglobin concentration (MCHC), the mean corpuscular volume (MCV), the mean corpuscular hemoglobin (MCH), and the red cell distribution width (RDW).
How do you interpret MCV?
MCV is elevated or decreased in accordance with average red cell size; ie, low MCV indicates microcytic (small average RBC size), normal MCV indicates normocytic (normal average RBC size), and high MCV indicates macrocytic (large average RBC size).
What is the relationship between MCV and MCHC?
Your MCH value is related to two other values, mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC). Together, MCH, MCV, and MCHC are sometimes referred to as red blood cell indices. MCV is a measurement of the average size of your red blood cells. MCH results tend to mirror MCV results.
What is MCV in RBC parameters?
Mean corpuscular volume (MCV), which measures the average size of your red blood cells. Mean corpuscular hemoglobin (MCH), which measures the average amount of hemoglobin in a single red blood cell.
What does low MCV mean?
Low MCV level Microcytic anemia is a type of anemia in which red blood cells are smaller than usual. Iron deficiency causes microcytic anemia. A person usually develops an iron deficiency due to an underlying health condition or factors such as diet and medications.
What does low MCV and high RDW mean?
a high RDW and typical MCV suggests an iron, B12, or folate deficiency, or possibly chronic liver disease. a high RDW and low MCV suggests iron deficiency or microcytic anemia. a high RDW and high MCV indicates a lack of B12 or folate, macrocytic anemia, or chronic liver disease.
What does high MCV and low MCHC mean?
For instance, low MCHC and low MCV could indicate iron-deficiency anemia, thalassemia, sideroblastic anemia, or lead poisoning. A high MCHC and low MCV could indicate spherocytosis or sickle cell disease. Normal MCHC and high MCV could mean a vitamin B12 or folate deficiency or liver disease.
What does elevated MCV mean?
High MCV means that red blood cells are too large and indicates macrocytic anemia. This condition can be caused by several factors including low folate or vitamin B12 levels or chemotherapy.
What happens when MCV is high?
If someone has a high MCV level, their red blood cells are larger than usual, and they have macrocytic anemia. Macrocytosis occurs in people with an MCV level higher than 100 fl . Megaloblastic anemia is a type of macrocytic anemia.
What can cause a raised MCV?
If your MCV goes up, it could indicate:
- Low vitamin B12 level.
- Folate deficiency (folic acid is a nutrient)
- Liver disease.
- Carbon monoxide poisoning.
- Aplastic anemia (a condition where the body stops producing sufficient red blood cells)
What does raised MCV mean?
