What is Vitamin B1?

Vitamin B1, also known as thiamine, is an essential nutrient that the body uses to derive energy from food, support the health of the nervous system, and optimize cardiac function.

Why should you have Vitamin B1 tested?

Testing vitamin B1 levels is useful for individuals at risk of deficiency, such as the elderly, people with alcohol dependency, and individuals with certain medical conditions that affect nutrient absorption. It can also be beneficial for those aiming to improve their overall well-being.

What does it indicate?

The test for vitamin B1 levels helps determine whether someone has an adequate level of this nutrient for healthy bodily functions. It indicates the body's efficiency in converting food into energy, the health of the nervous system, and cardiac function.

What does a high Vitamin B1 level mean?

A high level of vitamin B1 is rare and usually indicates adequate intake through diet or supplements. It is important to find a balance, as extremely high doses can be harmful.

What does a low Vitamin B1 level mean?

A low level of vitamin B1 may indicate a deficiency, which can lead to health problems such as beriberi, Wernicke-Korsakoff syndrome, muscle weakness, and diminished cardiac function.

Frequently asked questions

Answers to what people usually want to know.

How does it work from order to result?

After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.

How quickly can I get tested?

Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.

Do I need to book an appointment?

At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.

Do I need to fast before the test?

    That depends on the test. Whether fasting is required, and from what time, is clearly stated in the instructions you receive after ordering. No surprises at the counter.

    When and how do I receive my result?

    It varies per analysis: from same-day to a few working days. Standard values often come back quickly; analyses that go to an external lab can take a bit longer. You get an email with a link to your digital result, including a short explanation per value.

    Where can I go for collection?

    We work with 1,000+ collection points across the Netherlands. After ordering you'll see which locations near you are available and you pick where you'd like to go.
