Why is my MCV level high?
When the MCV value is increased, the RBC is said to be abnormally large, or macrocytic.
This is most frequently seen in megaloblastic anemias (e.g., vitamin B12 or folic acid deficiency).
When the MCV value is decreased the RBC is said to be abnormally small, or microcytic..
Can dehydration cause high MCV?
High values can indicate polycythemia or dehydration. MCV (Mean Corpuscular Volume) is the average size of red blood cells in a blood sample. MCV results are often used to classify anemias.
What diseases cause large red blood cells?
Advertising & SponsorshipVitamin B-12 deficiency.Folate deficiency.Liver disease.Alcoholism.Hypothyroidism.A side effect of certain medications, such as those used to treat cancer, seizures and autoimmune disorders.Increased red blood cell production by the bone marrow to correct anemia, for example, after blood loss.More items…
What happens if MCH is low?
A low MCH value typically indicates the presence of iron deficiency anemia. Iron is important for the production of hemoglobin. Your body absorbs a small amount of iron that you eat in order to produce hemoglobin.
What is MCV normal range?
Mean corpuscular volume (MCV) measures the average red blood cell volume, meaning the actual size of the cells themselves. A normal range for MCV is between 80 and 96 femtoliters per cell.
What does it mean when MCV and MCH are low?
Common conditions resulting in a hypochromic microcytic anemia (low MCV and MCH) include thalassemia and iron deficiency; and, less commonly, anemias associated with chronic inflammatory conditions, genetic determinants for Hb C, congenital defects in copper metabolism, some forms of sideroblastic anemia, and other …
Is high MCV serious?
Macrocytosis is a useful diagnostic indicator of alcoholism. MCV values greater than 100 fl in patients with liver disease almost invariably indicate alcohol-related disease.
How long does it take for MCV to return to normal?
As a result, red blood cells are not produced properly and become abnormally large, and the MCV result becomes higher than normal. Stopping heavy drinking allows the bone marrow to recover, and the MCV usually returns to normal within two months.
What causes low MCV?
The MCV will be lower than normal when red blood cells are too small. This condition is called microcytic anemia. Microcytic anemia may be caused by: iron deficiency, which can be caused by poor dietary intake of iron, menstrual bleeding, or gastrointestinal bleeding.
What does it mean when your MCV and MCH are high?
High MCH scores are commonly a sign of macrocytic anemia. This condition occurs when the blood cells are too big, which can be a result of not having enough vitamin B12 or folic acid in the body. High MCH scores may also be the result of the following: liver diseases.
What are symptoms of high MCV?
Your health care provider may have ordered a complete blood count, which includes an MCV test, as part of your regular checkup or if you have symptoms of a blood disorder. These symptoms include: Fatigue. Unusual bleeding or bruising.
