Included Markers
7 markersIron (Serum), Transferrin Saturation, Vitamin B12, Vitamin D (25-OH), Ferritin, Transferrin, Basic Blood Count
A comprehensive panel combining a complete blood count (CBC) with iron studies (Ferritin, Iron, Transferrin, Transferrin Saturation), Vitamin B12, and Vitamin D. This panel provides a broad view of your blood health and nutritional status in a single blood draw.
Why this test?
Fatigue and low energy can have many possible explanations, including iron status, vitamin levels, and blood cell counts. Rather than testing these separately, this panel combines them into one draw, making it easier to see the broader picture and identify whether any of these common factors may be contributing.
Who is this test for?
This test may be relevant for adults who want a combined overview of their blood health, iron status, and vitamin levels. It can be useful for those experiencing tiredness or low energy, for those on restricted diets, or for anyone who wants a thorough nutritional and haematological snapshot.
What is tested?
- Complete Blood Count (CBC): red blood cells, white blood cells, haemoglobin, haematocrit, platelets, and related indices.
- Ferritin: reflects the body's iron stores.
- Iron (Serum): the amount of iron circulating in the blood.
- Transferrin: the protein that transports iron; helps indicate whether the body is requesting more iron.
- Transferrin Saturation: the percentage of iron-carrying capacity being used.
- Vitamin B12: involved in nerve function and the production of red blood cells. Deficiency may be associated with fatigue and neurological symptoms.
- Vitamin D: plays a role in bone health, immune function, and general wellbeing. Levels can be lower during seasons with limited sunlight.
What can this test tell you?
By combining a CBC with iron markers and vitamins, this panel may help identify whether fatigue, for instance, could be associated with low iron stores, vitamin deficiency, or changes in blood cell counts. Seeing all of these values together allows for a more informed conversation with your healthcare provider.
How is the sample collected?
A blood sample is drawn at a certified sample point (afnamepunt). There are 700+ locations across the Netherlands. After placing your order, you can select a location and time that suits you.
When is this test useful?
This test may be useful when you want a comprehensive picture of your blood health and nutritional status without ordering multiple individual tests. It can serve as a general health check or as a way to investigate persistent fatigue or low energy.
What do the results mean?
Results are presented with reference ranges for each marker. With a panel of this breadth, it is not uncommon for one or two values to fall slightly outside the reference range. Iron-related markers should be viewed together for the most informative picture. A healthcare provider can help determine which findings, if any, may benefit from further attention.
What happens after the results?
Your results are available in your personal dashboard. If you have questions about the values, or if you would like guidance on diet, supplementation, or next steps, discussing the results with your healthcare provider is recommended.
Frequently Asked Questions
Fasting is not strictly required, but testing in the morning before eating may provide more consistent iron results. Discuss timing with your healthcare provider.

What We Test
This test includes 7 biomarkers for a clear picture of your health.
| No. | Biomarker | Unit | Turnaround |
|---|---|---|---|
| 01 | Iron (Serum) Serum iron measures the amount of circulating iron in your blood. Iron is essential for haemoglobin production, oxygen transport, and energy metabolism throughout the body. | umol/l | 5 days |
| 02 | Transferrin Saturation Transferrin saturation measures the percentage of the iron-transport protein transferrin that is occupied by iron. It is a key indicator of your body's iron status and helps distinguish between different causes of iron-related disorders. | % | — |
| 03 | Vitamin B12 Vitamin B12 is considered essential for red blood cell formation, neurological function, and DNA synthesis. Deficiency may develop gradually and is sometimes associated with dietary patterns. Healthcare providers can help interpret your results. | pmol/l | 3 days |
| 04 | Vitamin D (25-OH) Vitamin D is a fat-soluble vitamin. Its main job is the absorption of calcium and phosphate from the gut. That makes it decisive for bone metabolism. The skin produces it under the influence of sunlight. Food and supplements supply a smaller share. | nmol/l | 3 days |
| 05 | Ferritin Ferritin is a protein that stores iron, so your ferritin level shows how large your iron reserve is. Serum iron only measures how much iron is circulating in your blood at that moment; ferritin describes the reserve behind it. That reserve empties before your haemoglobin falls, so a low ferritin can already cause symptoms while your blood count still looks normal. Ferritin also rises with inflammation, infection and liver strain, which is why it can only be read properly alongside a CRP. Commonly used reference values are 30 to 400 µg/l for men and 15 to 150 µg/l for women, but your own laboratory report is what counts. | ug/l | 2 days |
| 06 | Transferrin Transferrin is the main protein responsible for transporting iron in the blood. It carries iron from the gut and storage sites to cells that need it, including bone marrow for red blood cell production. | g/l | 2 days |
| 07 | Basic Blood Count A basic blood count measures three core values in your blood: hemoglobin, white blood cells and platelets. Together they say something about oxygen transport, immune defence and clotting. It is a simple baseline check, without the red-cell indices and white-cell differential of a complete blood count. | — | 2 days |
| Your result arrives once the slowest test is finished: 5 days. This is indicative; turnaround varies per laboratory. | |||
Preparation
-
Been ill? Wait a little
RequiredHad a fever, an infection or a vaccination in the past 2 weeks? Wait with the draw until you are fully recovered. These values react to inflammation and would give a distorted picture.
-
Preferably fasting
RecommendedComing fasting gives a slightly cleaner value, but it is not required. If it suits you, eat nothing from 22:00 the evening before and drink only water.
-
Preferably in the morning
RecommendedA morning draw makes this value easiest to compare with its reference range. Plan the draw before 10:00 if you can.
- Water is always fine. Drink as usual beforehand, it makes the draw easier.
- Take your usual medication, unless your own doctor told you otherwise.
