Vitamin B Complete - What is it?

This blood test measures vitamin B12 in the blood. Vitamin B12 (cobalamin) is needed for production of red blood cells so that you can transport oxygen optimally. In the event of a deficiency, you may initially experience similar symptoms to anemia: fatigue. In addition, vitamin B12 plays an important role in the proper functioning of the nervous system, so neurological complaints such as tingling are often associated with a deficiency.

This test is excellent for measuring the effect of vitamin B vitamin supplements or vitamin pills. It sometimes happens that you unintentionally have too much vitamin B value.

What do we determine?

Vitamin B12

Vitamin B12 (cobalamin) is necessary for the production of red blood cells and proper functioning of the nervous system. It is almost exclusively found in animal products, so vegans are recommended to get tested if they have symptoms. With a deficiency you will experience tingling, fatigue, dizziness, memory loss and muscle weakness.

When to choose this test?

Choose this vitamin B12 blood test when:
  • You want to know what the effect of vitamin supplements or vitamin pills is
  • You have been feeling tired for a while and think it is due to vitamin B12 deficiency
  • You suffer from fatigue, hair loss, skin abnormalities, tingling in the fingers
  • You have complaints of anemia (pale vision, dizziness, palpitations, fatigue)
  • You are vegan and you want to know your vitamin B12 value


When to test?

In case of complaints described above, it is recommended to do this test once. When using vitamin supplements, it is recommended to do this test every 6 months - 12 months.
The accuracy of the test for Vitamine B12 is conducted through ISO-certified laboratories. The accuracy of a test method is expressed in terms of specificity and sensitivity. However, the most important aspect is that the results are interpreted and accepted among general practitioners and hospitals. This is the case with our venous samples. Mutual acceptance may not always be present due to potentially reduced reliability with a capillary sample.
Most tests generally take 24-48 hours. Tests that go through an LC-MS method generally take longer, think about an average of 3-7 working days. Additionally, it also depends on the location. Some locations do the analysis themselves and others outsource it to another lab.
Interpreting the results of Vitamine B12 is not always easy and should be seen in the broader picture, along with anamnesis and physical examination. In the doctor's advice section, the query in which you can already outline your complaints is taken into account, otherwise, the results are interpreted in conjunction with the other results. If necessary, the doctor can call to ask about physical abnormalities. You don't have to interpret the results yourself because there is always advice and explanation from the doctor.
If the results of the test for Vitamine B12 are clinically significantly abnormal, the doctor will contact you by phone. If you are not reachable, you will receive an email. This includes advice and an explanation of the abnormal results and what you can do about them. If you need a prescription or referral, we can help with that.
The costs of Vitamine B12 can be found on the product page. Depending on your insurance and additional packages, you may be reimbursed for these costs for Vitamine B12. For example, tests for IVF treatment are often reimbursed. After your order, you will receive an invoice that you can submit to your insurance.
The ordering process is easy. You can add a Vitamine B12 test or the tests you want to your shopping cart. In step two, you fill in your details and pay. Then you will receive an email confirmation and you can go to a collection location. After you have been there, you will receive the results of the Vitamine B12 test in your Portal.

You can easily make an appointment for Vitamine B12 blood test after your order in your Portal. You can visit almost daily in all major cities in the Netherlands. In smaller cities, you can visit on certain days. At certain locations, it is also possible to visit on weekends.
An interpretation by a doctor or an explanation is included in the Vitamine B12 test. The explanation takes into account the query that you can specify in your Portal after ordering.
For blood tests, we always use venous sampling. This is the gold standard for blood collection. Over-the-counter tests, such as a finger prick test, use the capillary route for blood collection. These do not always give the same results and the accuracy depends on how, where, and with which technique the collection is done. The advantage, of course, is that the test is easier and less painful to take.
You can always pay with iDeal and credit card (VISA, Mastercard, and Amex). This also includes Apple Pay. The phlebotomists at the collection location cannot accept cash payments.
The results of Labplusarts can be shared with your general practitioner at your request. However, you can also easily arrange this yourself by downloading the result in PDF format. Because we use comparable test methods as the general practitioner, the results are interchangeable and comparable so that comparisons can be made well.
