The three items of anemia refer to serum ferritin, vitamin B12, and folic acid. If they are low, it usually suggests the deficiency of these three items, but a normal hemoglobin suggests that they are not serious enough to reach the level of anemia. If serum ferritin, vitamin B12 and folic acid are deficient, the intake of related nutrients can be added to the usual diet; if serum ferritin is low for a long period of time, it may lead to iron-deficiency anemia; and the deficiency of vitamin B12 and folic acid may lead to megaloblastic anemia. Hemoglobin value is normal, then suggests that there is no anemia, at this stage in the lack of hematopoietic raw materials, but not serious enough to the point of anemia. If the anemia triple low hemoglobin is normal, you can seek medical advice and supplement the relevant elements appropriately under the advice of the doctor.
