What does low MCV and MCH indicate?

What does low MCV and MCH indicate?

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 …

What does low MCV MCH MCHC and high RDW mean?

It may also indicate chronic liver disease. High RDW and low MCV. This suggests iron deficiency or microcytic anemia. High RDW and high MCV. This indicates a lack of B-12 or folate.

What causes MCV to decrease?

The common causes of microcytic and hypochromic anemia (decreased MCV and MCH) are as follows: Iron deficiency anemia. Anemia of chronic disease. Thalassemia.

What can cause slightly elevated red blood cell count?


  • Heart disease (such as congenital heart disease in adults)
  • Heart failure.
  • A condition present at birth that reduces the oxygen-carrying capacity of red blood cells (hemoglobinopathy)
  • High altitudes.
  • COPD (chronic obstructive pulmonary disease) exacerbation — worsening of symptoms.

Is high RDW serious?

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 is MCH normal range?

The normal values for MCH are 29 ± 2 picograms (pg) per cell. MCHC indicates the amount of hemoglobin per unit volume. In contrast to MCH, MCHC correlates the hemoglobin content with the volume of the cell.

How high is too high for MCV?

An average MCV score is between 80 and 95. If the MCV goes up to an extreme of 125, it may indicate vitamin B12, folate deficiencies, or cold agglutinin disease.

What causes RBC to be slightly elevated?

High red blood cell count may be caused by low oxygen levels, kidney disease or other problems. Your body may increase red blood cell production to compensate for any condition that results in low oxygen levels, including: Heart disease (such as congenital heart disease in adults)

What causes high RBC levels?

A high RBC count could be caused by a number of health conditions or health-related factors, including: smoking. congenital heart disease. dehydration (for example, from severe diarrhoea) low blood oxygen levels (hypoxia)

What does an elevated RBC mean?

High red blood cells count may result from impaired ability of the cells to carry oxygen. Elevated RBC value occurs at high altitudes due to low ambient oxygen levels. Strenuous exercises can also cause enhanced red blood cells production because increased muscle mass requires more oxygen.

What causes elevated RBC in blood test?

Medical conditions that can cause an increase in red blood cells include: Heart failure, causing low blood oxygen levels Congenital heart disease (born with it) Polycythemia vera (a blood disorder in which the bone marrow produces too many red blood cells) Kidney tumors Lung disease, such as emphysema, COPD, pulmonary fibrosis (lung tissue becomes scarred) Hypoxia (low blood oxygen levels)
