Brain Fog

Are you experiencing persistent fatigue, low energy, shortness of breath, or noticeable hair loss? Low ferritin, the protein that stores iron in your body, is one of the most common and overlooked causes. This simple home blood test measures your exact iron storage levels, helping you identify iron deficiency before it progresses to anaemia. Ferritin deficiency is commonly linked to: Chronic fatigue or low energy Hair thinning or hair loss Brittle nails or pale skin Weakness or difficulty concentrating Early detection allows for targeted action, whether that's dietary changes, iron supplementation, or further medical evaluation. What is tested: Serum Ferritin — a sensitive marker of your body's available iron stores and the most reliable indicator of iron-deficiency anaemia. Looking for a broader test? Compare our Iron Status Profile for ferritin and iron markers, our Nutrients Blood Test for Vitamin D, Ferritin and Folate, or our Fatigue & Tiredness panel for a wider selection of biomarkers. These are alternatives to the standalone Ferritin test. Also worth considering: While ferritin checks your iron storage, unexplained fatigue is also frequently caused by thyroid imbalances. If you want a complete picture in one sample, consider adding our Thyroid Profile (TSH, Free T3 and Free T4) to your order. Your results: Delivered as a secure PDF report to your email within 3 working days of your sample arriving at our laboratory. Results are quantitative, showing your exact ferritin level alongside reference ranges and notes for any values outside the normal range. All samples are processed in a CQC-regulated UK laboratory.
