Iron Status

Iron is involved in oxygen transport, energy production, and immune function. Women who menstruate are more likely to experience reduced iron levels due to monthly blood loss. Symptoms of low iron can be subtle and develop gradually, making blood testing a useful way to check iron status before symptoms become pronounced.

This test may be relevant for women who:

• Experience fatigue, lightheadedness, or reduced exercise tolerance
• Have heavy menstrual periods
• Follow a diet that may be lower in iron (vegetarian or vegan)
• Want to check their iron stores as part of a general health assessment

This panel measures four iron-related markers:

• Ferritin: reflects the body's iron stores; low ferritin is often one of the earliest signs of iron depletion
• Iron (Serum): the amount of iron circulating in the blood
• Transferrin: a protein that transports iron; levels may rise when iron stores are low
• Transferrin Saturation: the percentage of transferrin that is carrying iron; provides context about how effectively iron is being transported

Together, these markers provide a picture of iron status. Low ferritin may suggest depleted iron stores, even if serum iron appears within the reference range. Elevated transferrin with low saturation can indicate the body is trying to compensate for low iron availability. These patterns may be discussed with a healthcare provider to determine whether further evaluation or dietary adjustments may be appropriate.

The test requires a blood draw at a certified sample point (afnamepunt). There are over 750 locations across the Netherlands. After placing your order, you can select a convenient location and schedule your visit.

This test may be considered when:

• You experience persistent tiredness or low energy
• You have heavy menstrual periods and want to monitor iron levels
• You follow a plant-based diet and want to check iron stores
• You are curious about whether iron status may be contributing to how you feel

Each marker is shown with your value and the reference range. Low ferritin is often the first indicator of depleted stores. Low serum iron combined with high transferrin and low saturation may suggest iron deficiency. Normal or high ferritin alongside low iron can sometimes be seen during inflammation, which a healthcare provider can help interpret. Results are intended to be discussed with your healthcare provider.

Fasting is recommended for the most accurate results. If you take iron supplements, it is advisable to avoid them for 24 hours before the blood draw. The test can be done at any point in your menstrual cycle.

Your results are typically available within a few working days. Each marker is shown with your value, the reference range, and an explanation. These results can serve as a starting point for a conversation with your healthcare provider about iron status and any appropriate next steps.
