A Ferritin Blood Test assesses iron reserves and monitors overall health.
This test measures ferritin, a protein storing iron. Abnormal levels (high or low) can indicate health issues needing further investigation. Ferritin differs from iron in red blood cells; it's an iron reservoir. Fast turnaround times, same-day or next-day results. Free online Health Dashboard tracks levels over time.
Key Details
Who Is This For?
Anyone experiencing unexplained fatigue, weakness, dizziness, or shortness of breath. Women with heavy menstrual periods, who are at higher risk of iron deficiency. Athletes and endurance sports participants, who lose iron through sweat and foot-strike hemolysis. Vegetarians and vegans who may not get enough dietary iron. People with a family history of hemochromatosis (hereditary iron overload).
What's Included
Preparation Required
Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.
Biomarkers Tested
1The primary iron storage protein. Ferritin reflects total body iron stores and is the first marker to drop in iron deficiency. However, ferritin also rises with inflammation, infection, and liver disease, which can mask true iron deficiency.
