what levels are low blood levels with anemia
When someone has anemia (low RBC count, hemoglobin, and hematocrit), the results of this test can help determine the cause and/or help classify the type of anemia. For example, for a person with anemia, an inappropriately low reticulocyte count often indicates decrease in red blood cell production in the bone marrow.
Deficiency of iron leads to decreased production of hemoglobin; low levels of hemoglobin in turn leads to production of smaller and hypochromic RBCs. Blood loss; diet low in iron; poor absorption of iron: Pernicious Anemia and B Vitamin Deficiency
