What is the Thyroid Function Test?
The Thyroid Function Test is a blood test that measures how well your thyroid gland is working. The thyroid plays a key role in regulating metabolism, energy, and overall bodily functions. The test measures the following biomarkers:
- TSH (Thyroid Stimulating Hormone): Regulates the production of thyroid hormones. Elevated TSH levels may indicate hypothyroidism (underactive thyroid), while low TSH levels may suggest hyperthyroidism (overactive thyroid).
- Free T4 (Free Thyroxine): The main thyroid hormone that controls the rate of metabolic processes in the body.
- Free T3 (Free Triiodothyronine): The active form of the thyroid hormone, responsible for stimulating energy production and oxygen use in cells.
Why should you take the Thyroid Function Test?
Testing TSH, Free T4, and Free T3 is essential for detecting and managing thyroid imbalances. It is especially useful for people who:
- Experience fatigue, weight changes, or mood fluctuations.
- Show symptoms of a slow or overactive metabolism.
- Have a family history of thyroid disorders.
- Are taking thyroid medication and need monitoring.
What does it indicate?
The Thyroid Function Test helps determine whether your thyroid produces too many or too few hormones, directly affecting:
- Energy levels and metabolism.
- Weight regulation and digestion.
- Heart rate and temperature control.
- Concentration and mood.
What does a high thyroid level mean?
High TSH levels may indicate hypothyroidism (underactive thyroid), where too little hormone is produced. High Free T4 or Free T3 levels may indicate hyperthyroidism (overactive thyroid), where too much hormone is produced.
What does a low thyroid level mean?
Low TSH levels may indicate hyperthyroidism, while low Free T4 or Free T3 levels usually suggest hypothyroidism. Both conditions require medical follow-up and appropriate treatment.

Indication-specific evidence
This test has clinical value for specific complaints or indications, but is not intended as screening without symptoms.
Rationale for this test
Dit pakket combineert TSH en vrij T4 (standaard schildklierdiagnostiek volgens NHG-richtlijnen) met vrij T3. De NHG-richtlijn stelt expliciet dat T3 of vrij T3 (fT3) geen meerwaarde heeft in de eerstelijnszorg. TSH en vrij T4 zijn wel sterk onderbouwd, maar de toevoeging van FT3 maakt dit pakket minder geschikt als standaard-screening zonder specifieke indicatie.

Practical information
Frequently asked questions
How does the fingerstick test work from A to Z?
After ordering we ship the collection kit to your home. You prick your fingertip, collect a few drops of blood, return it in the envelope, and receive your result digitally by email.
How do I collect my blood sample?
A small prick on your fingertip lets you collect a few drops into a tube. The instructions include step-by-step photos and video, so no guessing required.
When and how do I receive my result?
Usually 2 to 5 working days after the lab receives your sample. You receive your laboratory report securely by email. It lists the measured values, units, reference ranges and any flags added by the laboratory.
What if the collection doesn't work?
Some people find the fingerstick tricky at first. Warm your hands, hang your arm down, and prick the side of the fingertip for better blood flow. If it still doesn't work, get in touch.
How do I return the collection materials to the lab?
Use the supplied return envelope and place it in the letter-mail bag inside a PostNL service point yourself as soon as possible. Do not hand it to counter staff or request track & trace. The instructions supplied with your test state when it must be sent.
What if I have questions or something doesn't work?
Feel free to contact us via WhatsApp, email or phone. We're happy to help you before, during or after your test. If the collection doesn't work, we'll arrange a solution or send new materials — no hassle.

“I am satisfied with the service”
I received a referral by email, just like from a GP. I did not have to send anything by post and could quickly visit a local blood collection centre. The results were fast and clear. The price was good, not too expensive, and all messages were secure.

“Very happy to have found this business”
Very happy to have found this business. We need to check our blood more often :) The process was easy. They sent me the kit at home, then I had to go to a clinic with the papers and they knew what they had to do. I got the results in less than a week.

“Smooth process and good support”
Amazing website experience. I ordered various tests for 2 people. We went to one of the supported centers and took samples. Also after the results were ready, I needed a letter from the laboratory and they prepared the letter for me in no time. Definitely recommended.

“Amazing service!”
Received a packet with everything needed, went to a walk in clinic (Amsterdam DC Clinic) where my blood was drawn and I was out the door within 5 minutes, and then after posting the samples, received results 2 days later. Results were easy to understand as well. Amazing service, would highly recommend!
