This test is ideal if you're experiencing constant tiredness, weakness, or noticing pale skin and brittle nails. It helps identify whether your fatigue is caused by low iron stores (iron deficiency) or, less commonly, excess iron buildup in your body. Many people use this test when they feel exhausted despite getting enough sleep, or when their doctor wants to investigate unexplained fatigue or anemia.
No fasting is needed for this test, so you can eat and drink normally beforehand. If you're taking high-dose biotin supplements (more than 5 mg per day), avoid taking them for at least eight hours before your blood draw, as biotin can interfere with test accuracy. Otherwise, no special preparation is required.
This test measures ferritin, the protein that stores iron in your body. Ferritin levels indicate how much iron your body has in reserve, which is crucial for producing healthy red blood cells, maintaining energy levels, and supporting immune function. Unlike tests that measure iron circulating in your blood at a specific moment, ferritin provides insight into your long-term iron storage capacity and can identify deficiencies before they become severe.
What this means
Your ferritin levels are below the optimal range, indicating depleted iron stores in your body. This can explain persistent fatigue, weakness, difficulty concentrating, and may lead to anemia if not addressed. Low ferritin is especially common in women with heavy periods, athletes, and those following plant-based diets.
Recommended actions
Increase iron-rich foods like red meat, poultry, beans, lentils, and dark leafy greens
Pair iron sources with vitamin C foods (citrus, bell peppers) to boost absorption
Consider an iron supplement after consulting with your doctor about appropriate dosage
Retest ferritin in 2-3 months to monitor improvement and adjust your approach
