Thyroid blood test - What is it?

The thyroid blood test determines your thyroid hormones. The thyroid is a gland in the neck area. Due to the secretion of hormones The thyroid gland has many functions, such as metabolism in the body.

After releasing a hormone from the brain, the thyroid gland will produce various thyroid hormones. We measure the most important of these in the blood test.

Please note, the TSH is determined. If different, then also the fT4. If you want to receive the fT4 in all cases, please indicate after your order.

What do we determine?

Blood: TSH

TSH stands for thyroid stimulating hormone. TSH is a hormone from the brain. It has an effect on the thyroid gland. When TSH comes into contact with the thyroid gland, it turns on the production of FT3 and FT4. These are the hormones that the thyroid gland releases. These hormones play an important role in the body's metabolism, especially FT3.

TSH increases during stressful moments in life, but also during moments of development of the body. TSH from the pituitary gland is stimulated by yet another hormone from the brain. It is actually inhibited by FT3 and FT4. It is therefore important to also determine this thyroid hormone, especially FT4, to determine thyroid diagnoses. However, when the TSH is normal, it is actually unnecessary to test the fT4. That is why we normally only test the fT4 with abnormal TSH values. If you would like to know both at the same time, please let us know.

Blood: FT4 (thyroxine)

FT4 or T4 or thyroxine are all names for the same hormone in different stages (the F stands for free). FT4 consists of, among other things, iodine (which is found in salt) and therefore plays an important role in the body's metabolism. FT4 is more common than FT3 in a 14:1 ratio. Through the blood test for this thyroid hormone in combination with the TSH determination, we can make a statement about the health of your thyroid gland.

Fasting test?

You do not need to be fasting for this blood test.

How does it work?

Professional testing

Self-tests do not always provide reliable and consistent results. That's why Labplusarts chooses to have the tests professionally administered at a testing location. We have made this process as simple as possible for you.

  1. 1

    Find the test that suits you

    Information on various health topics and a clear overview of our extensive test offerings. Through the website, you can easily determine which test may be relevant for you. Do you need assistance in making a choice or would you like to customize your own package? Feel free to contact us.

  2. 2

    Choose a testing location

    We conduct tests at 350+ locations across the Netherlands, ensuring there is always a location near you. During the ordering process, you can easily select your preferred testing location, and after payment, you can schedule an appointment. Choose where and when it suits you.

  3. 3

    Get tested

    During your appointment, one of our medical professionals will collect your sample. Subsequently, your sample will be examined in the laboratory.

  4. 4

    Truly reliable results with understandable explanations

    Because your sample is taken professionally, the results are consistent. Your test results are evaluated by one of our own doctors and accompanied by thorough advice. We believe it's important that you understand what the results mean for you. We ensure this by providing explanations about the test and the significance of your values.

When to choose this test?

Choose the thyroid blood test when:
  • Your general misunderstood have complaints such as fatigue
  • You get hot quickly, feel agitated, hair loss, stretch marks, concentration problems, diarrhea / constipation, lose weight quickly or gain weight quickly.
  • You are already familiar with a slow (hypothyroidism) or a fast (hyperthyroidism) thyroid and want a check.
  • You experience unexplained depression symptoms.


When to test?

It is recommended for complaints described here to do this test once and then every 6-9 months after starting medication. If the results are negative, no follow-up testing is necessary. If the results are inconclusive, we will conduct further research for antibodies (Graves' disease, Hashimoto's disease )
The accuracy of the test for Schildklier 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 Schildklier 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 Schildklier 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 Schildklier can be found on the product page. Depending on your insurance and additional packages, you may be reimbursed for these costs for Schildklier. 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 Schildklier 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 Schildklier test in your Portal.
We are certified-ready according to the NEN 7510 and 7512 standards for secure data transfer in healthcare. The Portal is secured with two-factor authentication. Your data is also encrypted. We do not send the results of Schildklier to third parties without permission, not even to your general practitioner without your consent.
The blood test for Schildklier must take place at one of the collection locations we provide. At certain locations, it is possible for a phlebotomist to come to you. You can indicate this during checkout. An appointment will then be made as soon as possible to come to your home.
You can easily make an appointment for Schildklier 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 Schildklier 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.
