Practical information
After ordering we ship the kit to your home. You spit into the tubes at the indicated times up to the fill line (~1ml), keep them cool and return them in the envelope. You receive your result digitally by email.
No eating, drinking, smoking or brushing teeth in the 30 minutes before collection. That gives the most reliable hormone values.
Yes for hormone tests like a cortisol day-profile — usually 4 moments spread across the day. Exact timings are in the instructions with your kit. Label tubes clearly with the time so the lab can identify them.
Spit gently into the tube up to the indicated fill line (~1ml). Don't blow or breathe forcefully — foam interferes with analysis. If you produce a lot of foam, tap the tube gently to settle it before continuing.
Rinse your mouth with water and wait 5 minutes. Don't use chewing gum or lemon — those interfere with hormone values.
Saliva analyses typically take about a week 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.
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.
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.

You can choose the tests yourself. Fast delivery and processing, clear instructions and affordable.
“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.
“A very good experience”
A very good experience! I received quick answers to my questions, a custom blood test was put together, everything was arranged smoothly, and I could have my blood drawn by a healthcare professional nearby. The results were available within a few days. In short, very satisfied!
“Very good customer service”
The customer service is very good. I had a complex request, which caused an issue at the blood collection centre. Customer service resolved it very well. They also offer a wide range of tests at a reasonable price.

Fantastic service! Very good customer service that responds quickly and thinks along with you. Good prices. I will definitely use BloedCheckup's services again.
“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!
“Great customer service”
I ordered a test through bloedcheckup.nl but later realized I no longer needed it. I contacted their support team, and they were very quick, responsive, and helpful in handling my cancellation. The whole process was smooth and efficient. Great customer service!
