What is the minimum normal serum ferritin level in ng/ml?

The minimum normal serum ferritin level is commonly considered to be around 100 ng/ml for most individuals. This value is significant because ferritin is a protein that stores iron, and its levels in the blood can indicate the body's iron stores. Adequate levels of serum ferritin are essential for various bodily functions, including Hemoglobin production and overall oxygen transport.

A serum ferritin level below 100 ng/ml may indicate inadequate iron stores, potentially leading to iron deficiency anemia if not addressed. While values higher than 100 ng/ml may be seen in individuals with sufficient iron stores or those who may be experiencing inflammation or other conditions, the key threshold in assessing normal ferritin levels typically starts at 100 ng/ml. Thus, the correct answer aligns with established guidelines in clinical practice for evaluating iron status in patients.
