It turns out that the low mean corpuscular hemoglobin concentration is caused by these factors

Blood test is a test we do frequently, whether it is for further study, new employment or routine physical examination. When we get the blood test report, some people's indicators are normal, while others have low mean corpuscular hemoglobin concentration. So what exactly causes this? Most people are confused. In fact, the low mean corpuscular hemoglobin concentration is caused by both pathological and physiological variations.

In addition to using hemoglobin as an indicator to judge anemia, the mean corpuscular hemoglobin concentration must also refer to the number of red blood cells. If the ratio of the two is unbalanced, it is necessary to further refer to the mean corpuscular volume, mean corpuscular hemoglobin amount, mean corpuscular hemoglobin concentration and red blood cell volume distribution width. Anemia caused by different causes can cause changes in the morphology of red blood cells. Examining the morphological characteristics of red blood cells can assist clinicians in finding the cause.

Pathological variation

Decreased: seen in microcytic hypochromic anemia (secondary anemia caused by cancer or infection; hyperferremia seen in sideroblastic anemia and lead poisoning and CO poisoning), systemic hemolytic anemia (thalassemia, hereditary spherocytosis, congenital pyruvate kinase deficiency).

Physiological Variation

Reduction: Vigorous muscle activity is reduced by about 4% and by about 10% in children under 6 months of age.

Drug effects

Reduce: New dicoumarol may cause microcytic hypochromic anemia.

The number of red blood cells should also be referred to. If the ratio of the two is unbalanced, further reference should be made to the mean corpuscular volume, mean corpuscular hemoglobin amount, mean corpuscular hemoglobin concentration and red blood cell volume distribution width. Anemia caused by different causes can cause morphological changes in red blood cells. Checking the morphological characteristics of red blood cells can assist clinicians in finding the cause. In the same medical record, changes in the three indexes can divide anemia into macrocytic anemia, normocytic anemia, simple microcytic anemia, and microcytic hypochromic anemia.

Through the editor's explanation, I believe everyone has known what the low mean corpuscular hemoglobin concentration is. In fact, the low mean corpuscular hemoglobin concentration may be caused by many factors, including the influence of drugs, physiology and pathology. If you want to know the specific influence, you have to do a comprehensive physical examination before you can check it out.
