What does the Serum Ferritin test measure?

Q: Why is Serum Ferritin measured?

Low ferritin (<30 ng/mL, or <50 ng/mL in some functional protocols) has been associated with restless legs, sleep disturbance, and inattention in children and adults, and iron supplementation in iron-deficient individuals may improve ADHD symptoms. Ferritin is the most accessible marker of iron status, but interpretation requires clinical context.

Serum Ferritin (Ferritin) is a clinical biomarker used in comprehensive-panels assessment. Ferritin is the primary intracellular iron-storage protein; serum ferritin generally correlates with total-body iron stores, though it is also an acute-phase reactant and can be elevated in inflammation, infection, or liver disease independently of iron status. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is Serum Ferritin?

Ferritin is the primary intracellular iron-storage protein; serum ferritin generally correlates with total-body iron stores, though it is also an acute-phase reactant and can be elevated in inflammation, infection, or liver disease independently of iron status. Iron is required for dopamine synthesis, myelination, and mitochondrial function in the central nervous system.
