The increase in ferritin levels per month depends on several factors, such as the dosage of iron supplements and the individual's initial ferritin level.
Ferritin is too low when its concentration in the blood is below the lower limit of reference values, which may indicate iron deficiency.
Results of a ferritin test are usually available the next business day after the sample is taken, depending on the laboratory's schedule.
Ferritin levels decrease by reducing iron intake in the diet and avoiding the use of iron supplements. In some cases,
Ferritin reference values vary by age and gender, but the generally accepted lower limit for adults is about 30 micrograms per liter.
Ferritin is measured with a blood test taken from a vein. The test measures the body's iron stores and is used to assess iron deficiency or iron overload.
Ferritin levels can drop quickly if the body uses its iron stores, for example, due to heavy bleeding or iron deficiency.
Ferritin levels can start to increase within a few weeks of starting iron supplements, but significant rise and replenishment of iron stores can take several months.
