This is called iron-deficiency anemia. Iron is an essential ingredient in hemoglobin. Environmental factors, medical conditions (inherited and acquired) and certain behaviors can also lead to microcytosis. The most common causes of microcytosis include: Iron deficiency: Nutritional deficiencies can prevent you from getting enough iron in your diet.
The normal MCV level for people over age 18 is between 78 and 98 cubic. micrometers (abbreviated um3). See the next section for a description of cubic. micrometers. The normal MCV level for newborns is between 95 and 121 um3. Between 6 months to 2 years, the average range is 70 to 86 um3. For boys ages 12. to 18 years, the average range is 78
A doctor typically measures someone’s MCV levels if they are presenting with: dry, cracked lips. cold intolerance. fatigue. bruising or bleeding easily. unexplained weight loss. cold hands and feet. looking paler than usual. jaundice.
Anemia is defined by low levels of circulating red blood cells or hemoglobin, the part of red blood cells that carries oxygen. Anemia of chronic disease is usually a mild or moderate condition. In mild cases, anemia may not be associated with any symptoms or may cause fatigue, paleness of the skin (pallor) and lightheadedness.
A low hemoglobin concentration and/or low hematocrit are the parameters most widely used to diagnose anemia, with the following cutoffs ( table 1 ): Females – Hemoglobin
Based on the erythrocyte mean corpuscular volume (MCV), anemia can be categorized as microcytic (MCV < 80 fL), normocytic (MCV 80–100 fL) or macrocytic (MCV > 100 fL) 21. Microcytic anemia is most commonly due to iron deficiency (other, less common causes include thalassemia and anemia of chronic diseases), while the differential diagnosis of
A low mean corpuscular volume warrants Hb electrophoresis. (MCV/red blood cell count) in children: ≥ 13 < 13 Consider other causes of growth delay in workup (chelation therapy toxicity

The main Testosterone Trials inclusion criteria were men ages 65 years or older, 2 serum testosterone level test results that averaged less than 275 ng/dL, and low risk of prostate cancer. 19, 20 Potential participants were excluded if their hemoglobin levels were less than 10.0 g/dL (to convert to g/L multiply by 10.0).
Low: A low value for MCV is anything under 80 fL. This means your RBCs are smaller than normal. Mean corpuscular volume levels and all-cause and liver cancer mortality.
