Ferritin 600ng/ml can be caused by the disorder of iron metabolism due to long-term massive blood transfusion, inflammation, multiple myeloma and other hematologic diseases. Ferritin is the form of stored iron in the human body, and ferritin is also a reaction protein, and its normal value range is 30~521ng/ml for men; 13~269ng/ml for women. 600ng/ml of ferritin is significantly higher than the normal value range. When there is no inflammation, malignant tumor (gastric cancer, lymphoma, etc.) and other diseases occurring in the human body, the value of ferritin reflects the iron load in the human body. When the total amount of red blood cell suspension infused into the body exceeds 20 U, iron deposition may occur, as evidenced by a significant increase in ferritin. When inflammatory diseases occur in the body, such as pneumonia and urinary tract infections, ferritin is reactively elevated and returns to normal after the inflammation subsides. When solid tumors such as gastric cancer, intestinal cancer, or hematologic malignant diseases such as lymphoma and multiple myeloma occur, iron metabolism disorders can occur, and ferritin will also be significantly elevated. Elevated ferritin due to iron deposition or iron metabolism disorder may lead to functional damage of heart, liver and other important organs, and when ferritin is greater than 1,000ng/ml, it needs to be treated with iron removal. It is recommended that the patient should consult the hematology department in time to identify the cause of the elevated ferritin and treat it.
