A ferritin value of 235 μg/L during pregnancy is too high. Ferritin values in the range of 35-55 μg/L are normal for women during pregnancy. The demand for ferritin is high during pregnancy due to the growth and development of the mother and the fetus. And if the ferritin is too high, then it may be caused by the following reasons. 1. Some women may have too much ferritin in their body due to excessive iron supplementation. 2. There may be hemolysis caused by thalassemia, which may lead to high ferritin in pregnant women. 3. High ferritin may also be caused by inflammation, liver disease, some tumors, and other causes in a woman’s body. Once the phenomenon of elevated ferritin during pregnancy occurs, it is recommended to go to the hematology department of the hospital for a comprehensive examination to clarify the cause of the disease and make targeted treatment.
