What causes low RBC and high MCV?
Iron deficiency also results in more variable red blood cell size (>20% RDW), and smaller (low MCV) and paler red blood cells (low MCH) [48, 49]. Nutrient deficiency of either folate or vitamin B12 results in enlarged red blood cells (megaloblastic anemia), with an MCV increased to a range of 105 to 160 fl [49].
What does it mean if my RBC is low and my MCH is high?
High MCH value can often be caused by anemia due to a deficiency of B vitamins, particularly B-12 and folate. Both of these vitamins are required by your body in order to make red blood cells. These types of anemia can develop if your diet is low in B vitamins or if your body does not absorb B-12 or folate properly.
What does high MCV and MCH mean in a blood test?
What Do High MCH Levels Mean? Your MCH will reflect your MCV. That means you’ll have more hemoglobin if your red blood cells are larger than normal. Red blood cells can grow too large when you have fewer of them than normal — a condition called macrocytic anemia. It’s more common if you’re elderly.
What does it mean if MCV and MCH are low in a blood test?
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 a low RDW bad?
Low RDW. A low value indicates that your red blood cells are uniform in size. This is desirable and not a cause for concern [3]. However, it is still possible to have a blood-related disease and low RDW levels [3].
Why would your RDW be high?
High results If your RDW is too high, it could be an indication of a nutrient deficiency, such as a deficiency of iron, folate, or vitamin B-12. These results could also indicate macrocytic anemia, when your body doesn’t produce enough normal red blood cells, and the cells it does produce are larger than normal.
What if MCV and MCH are low?
What does it mean when RDW is low on blood test?
A low RDW means your red blood cells are all about the same size. A high RDW means you have both very small and very large red blood cells. You may also have a “normal” RDW.
What does a low RDW indicate?
Why is RDW low in blood test?
Lower than normal numbers of RBCs may occur with bleeding, bone marrow failure, malnutrition, kidney disease, overhydration, or pregnancy. Several drugs affect the level of RBCs and may make it higher or lower than normal.
