Vitamin and Iron Panel

Iron and Vitamin D are nutrients that play a role in many body functions, from energy levels and immune function to bone health. Measuring multiple iron-related markers (not just one) gives a more nuanced view of iron status, while Vitamin D is a commonly checked nutrient, especially in regions with limited sunlight.

This test may be relevant for adults who want insight into their iron and vitamin D levels. It can be useful for those experiencing fatigue or low energy, for those who follow a restricted diet, or for anyone whose healthcare provider has suggested checking these values.

• Ferritin: reflects your body's iron stores. Low ferritin may indicate depleted iron reserves.
• Iron (Serum): the amount of iron circulating in the blood at the time of the test.
• Transferrin: a protein that transports iron in the blood. Its level can help indicate whether the body is requesting more iron.
• Transferrin Saturation: the percentage of transferrin that is carrying iron. Helps assess how much of the iron transport capacity is being used.
• Vitamin D: a vitamin involved in bone health, immune function, and other processes. Levels can be lower in seasons with less sunlight.

The results may indicate whether your iron stores and vitamin D levels fall within expected ranges. Low ferritin with low transferrin saturation, for example, could suggest that iron reserves are running low. Vitamin D levels outside the reference range are common, particularly in the Netherlands during autumn and winter months.

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 suits you.

This test may be useful when you want to check your iron and vitamin D levels, for example if you have been feeling tired, if you follow a vegetarian or limited diet, or simply as part of a general health check.

Results are presented with reference ranges for each marker. Iron-related values should be looked at together for the most informative picture. A healthcare provider can help you understand what the results may mean and whether any adjustments to diet or supplementation could be considered.

Fasting is recommended for more consistent iron results. Avoid iron supplements for 24 hours before the blood draw, as they can temporarily raise serum iron levels.

Your results are available in your personal dashboard. If values fall outside the reference range, or if you would like guidance on diet or supplementation, discussing the results with your healthcare provider is recommended.
