Chronic fatigue, pallor, hair loss, or weak immunity are often attributed to stress or the season. But the cause may be hidden in a single test - ferritin.<\/strong> This protein reflects the actual iron reserves in the body. And if the ferritin level is low, even with normal hemoglobin, the body is already experiencing an iron deficiency.<\/p>\n

Ferritin levels are one of the most important markers that doctors evaluate when they suspect anemia, chronic fatigue, thyroid disorders, or when examining athletes. Monitoring this indicator helps prevent serious metabolic disorders, especially in women, vegetarians, donors, or people with chronic diseases.<\/p>\n

What is ferritin?<\/h2>\n

Ferritin<\/a> is a protein that stores iron in cells in a safe, inactive form. It is main iron depot<\/strong> in the body. When the body needs iron for blood formation, enzyme synthesis, or immune support, it is released from ferritin.<\/p>\n

The serum ferritin level reflects iron reserves<\/strong>, rather than its transport or circulating amount. This makes ferritin a more accurate marker of iron deficiency than hemoglobin.<\/p>\n

Ferritin levels<\/h2>\n

Normal ferritin values depend on age, gender, and physiological state (e.g., pregnancy).<\/p>\n

A decrease below 30 ng\/mL may indicate depletion of iron stores even with normal hemoglobin.<\/p>\n
