Serum ferritin

When we have a physical examination, sometimes we need to check the serum ferritin level. The serum ferritin level can tell us whether we have anemia and help us understand our physical condition. You should learn and understand more about this kind of knowledge, so that you can have a clearer understanding of your physical condition and help yourself protect your health.

Because serum ferritin exists in the blood, as long as we test the serum ferritin level, we can know whether the body's blood content is normal. You can also understand the health status of your body by looking at the status of serum body proteins.

feature

①Iron deficiency anemia.

② Lack of storage iron.

③ Monitoring of long-term oral iron therapy

④Differential diagnosis of anemia.

⑤ Monitoring of people who are prone to iron deficiency (pregnant women, blood donors, young children and hemodialysis patients).

⑥ Iron overload.

⑦ Monitoring of long-term iron transfer therapy.

Reference value

Men: 30-400ug/L. Female: 12-150 μg/L

Clinical significance

Increased SF

① Increased iron storage in the body: primary hemochromatosis, secondary iron overload.

② Increased ferritin synthesis: inflammation, tumors, leukemia, hyperthyroidism, etc.

③Anemia: hemolytic anemia, aplastic anemia, pernicious anemia

④Increased tissue release: liver necrosis, chronic liver disease, etc.

SF reduction

Decreased SF is common in iron deficiency anemia, massive blood loss, long-term diarrhea, malnutrition, etc. .Iron deficiency can be diagnosed if SF is lower than 15μg/L. It can also be used as an indicator for epidemiological surveys of malnutrition. If SF is greater than 100 μg/L, iron deficiency can be ruled out.

The above is an introduction to some knowledge about serum ferritin. I believe that after reading it, you will have a better understanding of this knowledge. We need to learn more about this kind of knowledge in our lives. Only in this way can we better understand our physical condition. If you want to protect your health, you must know your physical condition.
