Complete Blood Count Test (CBC)
Clinical significance
Mean corpuscular volume, or MCV, is a measurement of red blood cell size.
A normal MCV range is roughly 80–100 fl .
If someone's MCV level is below 80 fl, they will likely develop or have microcytic anemia. A low MCV (called microcytosis ) means red blood cells are small (RBC). A low MCH value typically indicates the presence of iron deficiency anemia. Iron is important for the production of hemoglobin.
MCV is used to classify anaemia as either microcytic, normocytic or macrocytic. A diagnosis of anaemia is based on haemoglobin levels less than 13 g/dl in males and 12 g/dl in females, and the MCV value can be used to classify anaemia as either microcytic, normocytic or macrocytic In microcytic anaemia, the average erythrocyte volume is smaller than normal, generally under 80 fl, and this finding is commonly observed in cases of chronic iron‐deficient anaemia, anaemia of chronic disease and thalassemias. Macrocytic anaemia is characterized by elevated MCV (generally over 100 fl) and is subcategorized as megaloblastic or non‐megaloblastic. Megaloblastic anaemia is caused by impaired DNA synthesis and commonly occurs in folate deficiency and vitamin B12 deficiency, while non‐megaloblastic anaemia occurs due to hepatic insufficiency, chronic alcoholism and rare congenital diseases.
By itself, large red blood cells (macrocytosis) do not cause any symptoms. However, they can help provide information about underlying health conditions. MCV values greater than 100 fl in patients with liver disease almost invariably indicate alcohol-related disease. If the MCV goes up to an extreme of 125, it may indicate vitamin B12, folate deficiencies, or cold agglutinin disease. A higher MCV value indicates that the red blood cells are larger than the average size.
Real ratings and reviews from the Healsens app on the App Store and Google Play.
That's when I turned to a nutritionist and ordered a blood test through Healsens. … Four months later, I retested. My biological age dropped to 24—nearly a decade younger than my real age.
Read on App Store →It helps me track main parameters, understanding what do they mean and correlations, and make critical analysis to make preventative changes. Hope too see new fichas soon!
Read on App Store →Everything is great! Excellent app! It's very convenient for storing all your test results! The only thing I wish was that you could record blood pressure readings for both arms, as this is sometimes important for blood pressure monitoring.
Read on Google Play →A useful app. It motivates me to lead a healthy lifestyle and monitor my diet. After the test results, I decided to change my diet – I cut out flour and chocolate. I lost 2 kg in about a week. We'll see how the test results look over time.
