What is Vitamin A?
Vitamin A is an essential nutrient crucial for maintaining healthy skin, vision, and immune system function. It also plays a role in growth and development.
Why should you test Vitamin A levels?
Measuring vitamin A levels can be useful in diagnosing nutritional deficiencies or assessing overall health. It is particularly helpful for people with symptoms of a deficiency or those at risk of excessive intake due to supplement use.
What does it indicate?
The test results can show whether vitamin A levels fall within a healthy range. This helps in identifying both deficiencies and excesses, both of which can cause health issues.
What does a high Vitamin A level mean?
A high level of vitamin A may indicate excessive intake, which can lead to vitamin A toxicity. This can cause symptoms such as headache, nausea, dizziness, and in severe cases, liver damage.
What does a low Vitamin A level mean?
A low level of vitamin A may indicate a deficiency, which can lead to night blindness, an increased risk of infections, skin problems, and other health issues.
Limited evidence in mainstream medicine
The scientific support for this test within mainstream Dutch healthcare is limited. The test is not included in NHG/FMS standard guidelines.
Rationale for this test
Vitamine A-bepaling in bloed is een gevestigde laboratoriumtest voor het diagnosticeren van deficiënties of toxiciteit. De test zelf is klinisch valide, maar wordt in de Nederlandse huisartsenpraktijk niet standaard gebruikt als screeningstest zonder specifieke indicatie. In de reguliere zorg wordt vitamine A-bepaling vooral ingezet bij verdenking op malabsorptie, chronische leverziekte of bij klinische tekenen van deficiëntie. Voor gezonde personen zonder klachten is de klinische meerwaarde beperkt.

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.

“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!
