Blood test vitamins, get quick insight into your vitamin deficiency
Vitamins are indispensable for a healthy body. They play an important role in your energy balance, your resistance and the functioning of your organs. In principle, you get enough vitamins if you eat a healthy and varied diet. Yet in practice it appears that many people have an unnoticed shortage. Especially in the winter months or with a one-sided diet deficiencies can occur. A vitamin test offers a solution if you want to know how your vitamin levels are doing.

Three steps to results
Is a blood test vitamin wise?
Not everyone notices immediately that he or she is deficient in certain vitamins. Yet a deficiency can cause long-term symptoms. Think of fatigue, lack of energy, concentration problems or disturbed sleep patterns. Lethargy, muscle weakness and decreased resistance can also be signs. If you stay around too long with a deficiency, serious health problems can arise. A vitamin test helps to get clarity and take targeted action.
Common deficits we measure
At OneDayClinic, you can have various vitamin levels checked. The most commonly requested tests are:
- Vitamin B12: Important for your nervous system, energy and blood production.
- Vitamin D: Essential for your bones, muscles and resistance.
- Folic acid (vitamin B11): Important for cell growth and the nervous system.
- Ijzer en ferritine: Betrokken bij je energieniveau en zuurstoftransport in je bloed.
We can measure these values quickly and reliably for you in our certified
laboratory.

How does a vitamin test at OneDayClinic work?
At OneDayClinic, you can get a quick and professional vitamin test without a referral from your doctor. You simply make an appointment online or by phone at one of our clinics. During your visit, an expert doctor or nurse will take some blood from you. This is done via a prick in your arm or, in some cases, with a simple finger prick. Then your blood is examined in an accredited laboratory.
You will receive the results via healthcare email. So you know quickly whether you have enough vitamins in your blood. Would you like more explanation about the result or do you need follow-up advice? Then we recommend that you contact your doctor or specialist. We do not provide medical advice or treatment plans.
