Iron Studies

Iron is involved in oxygen transport, energy production, and immune function. A single iron level can fluctuate throughout the day and may not tell the whole story. By including Ferritin (storage), Transferrin (transport protein), and Transferrin Saturation (how much transport capacity is being used), this panel provides a broader view of how your body is managing iron.

• Men experiencing persistent fatigue, reduced endurance, or unexplained weakness that could be associated with iron status
• Those with a diet that may be lower in iron-rich foods (for example, plant-based diets)
• Men who want to monitor iron stores, particularly if previous tests showed borderline values
• Those who engage in high-volume training, which may influence iron turnover

• Iron Serum (umol/l): the amount of iron circulating in the blood. This value can vary throughout the day and with recent meals.
• Ferritin (ug/l): reflects iron stores in the body. Low Ferritin may indicate depleted reserves, while elevated Ferritin can be associated with inflammation or iron overload.
• Transferrin (g/L): the primary protein responsible for transporting iron through the bloodstream. The body may produce more Transferrin when iron stores are low.
• Transferrin Saturation (%): the percentage of Transferrin that is carrying iron. This calculated value helps indicate whether there is enough iron available for the body's needs.

Taken together, these markers may help distinguish between different states of iron balance. For example, low Ferritin with elevated Transferrin could suggest the body is compensating for depleted iron stores. Normal Serum Iron with low Transferrin Saturation might indicate that iron is present but not being effectively utilized. Elevated Ferritin without other signs of deficiency may be associated with inflammation rather than true iron excess. The combination of all four values provides more nuance than any single marker.

A blood sample is drawn at a certified sample point (afnamepunt). There are over 750 locations across the Netherlands. After placing your order, you can select a location and time that works for you. The appointment typically takes around 10 to 15 minutes.

This panel may be useful when experiencing symptoms that could be associated with iron imbalance, such as persistent tiredness, reduced physical performance, or difficulty recovering from exercise. It can also be relevant for men who want to establish a baseline of their iron status or who are tracking changes over time.

Results are presented with reference ranges for each marker. Iron metabolism involves multiple interacting components, so values should be interpreted together rather than in isolation. A healthcare provider can help determine whether the overall pattern suggests adequate iron status or whether further investigation may be warranted.

Fasting is recommended for more consistent results. Avoid iron supplements for 24 hours before the blood draw, as they can temporarily elevate Serum Iron and affect the accuracy of the results.

Your results are typically available within a few business days in your personal dashboard. The report includes measured values alongside reference ranges. If your results suggest an imbalance, consider discussing them with a healthcare provider who can advise on any next steps.
