Ferritin (FERR)

Ferritin is a protein that stores iron and releases it when the body needs it. In a blood test, ferritin levels reflect the amount of stored iron in the body. For females, normal ferritin levels typically range from 12 to 150 nanograms per milliliter (ng/mL), though this can vary slightly depending on the laboratory. Low ferritin levels in women may indicate iron deficiency, which can lead to anemia, fatigue, and other symptoms. This is particularly common in women due to menstruation, pregnancy, or dietary insufficiencies. On the other hand, high ferritin levels could suggest conditions such as hemochromatosis (excess iron storage), liver disease, or chronic inflammation. Monitoring ferritin is crucial for diagnosing and managing iron-related disorders and overall health. It provides insight into both iron deficiency and overload, which are important for maintaining optimal physiological function.
