Introduction

Under normal circumstances, ferritin is an important indicator reflecting the body's iron storage status, and elevated levels typically suggest increased iron load or the presence of certain pathological conditions. An increase in ferritin alone represents only one abnormal parameter and must be interpreted in conjunction with clinical symptoms and other examinations, such as liver function tests, complete blood count, iron metabolism parameters, and imaging studies, to comprehensively determine the underlying cause. A diagnosis should not be made based solely on this parameter.

Under normal circumstances, serum ferritin is an important indicator reflecting the body's iron storage status. Elevated levels usually suggest increased iron load or the presence of certain pathological conditions. A detailed analysis is as follows:

The normal reference range for ferritin is 15-200 μg/L for males and 3-100 μg/L for females. Common causes of elevated ferritin levels include excessive iron load, such as iron accumulation caused by primary hemochromatosis, repeated blood transfusions, or inappropriate iron supplementation; liver diseases, such as viral hepatitis and cirrhosis, in which damaged hepatocytes release stored ferritin into the bloodstream; malignant tumors, such as leukemia, liver cancer, and lung cancer, in which tumor cells can synthesize and secrete ferritin, leading to elevated levels; hemolytic anemia, where extensive destruction of red blood cells releases iron, increasing ferritin synthesis; and additionally, during acute infections, inflammation, or tissue damage, ferritin may mildly increase as an acute-phase reactant protein.

An elevated ferritin level is only one abnormal indicator and must be interpreted in conjunction with clinical symptoms and other examinations, such as liver function tests, complete blood count, iron metabolism parameters, and imaging studies, to comprehensively determine the underlying cause. Disease diagnosis should not be based solely on this parameter. If elevated ferritin is detected, timely medical consultation is recommended for further investigation to identify the specific cause and implement targeted management accordingly.

What is the normal ferritin level?

Under normal circumstances, the normal range of serum ferritin for adult males is 15-200 μg/L, while for adult females it is 12-150 μg/L. Ferritin is a soluble tissue protein that stores iron, and its levels reflect the body's iron reserves. The normal ranges differ between males and females primarily due to factors such as menstrual blood loss in women.

What foods can quickly replenish low ferritin levels?

In general, low ferritin levels can be supplemented by consuming foods such as red meat, poultry, legumes, spinach, and dried fruits. Additionally, under medical guidance, medications such as ferrous sulfate tablets, ferrous gluconate syrup, iron dextran dispersible tablets, ferrous succinate tablets, and ferric protein succinate oral solution may be taken for supplementation. If other physical discomfort symptoms are present, prompt medical treatment at a hospital is recommended.

What causes elevated serum ferritin levels, and what should be done?

Serum ferritin generally refers to blood serum ferritin. Under normal circumstances, elevated serum ferritin levels may be caused by dietary factors, vigorous exercise, hemolytic anemia, hyperthyroidism, aplastic anemia, and other factors. It is recommended to seek timely medical consultation at a hospital to determine the underlying cause and receive targeted treatment. In daily diet, foods rich in iron should be avoided temporarily.

What are the best ways to supplement iron and improve blood health?

There is generally no such thing as "the best method for iron supplementation and blood building." Iron supplementation and improving blood levels usually can be achieved through regular作息 (作息 should be replaced with appropriate term like "rest" or "lifestyle routine"), moderate exercise, increasing intake of iron-rich foods, properly taking iron supplements, and traditional Chinese medicine regulation. During the process of iron supplementation, it is recommended to regularly recheck blood routine, serum ferritin, and other related indicators to monitor the effectiveness of iron supplementation and the body's recovery status.
