The follow-up test measures IgE antibodies separately against each of the 6 foods from the fx5 food allergen screen. Where the screen only shows whether you are sensitized to at least one of them, here you get a separate result per food.
After a positive fx5 screen and a clear reaction shortly after eating, such as itching in the mouth, hives, swelling, vomiting or shortness of breath, if you want to know which of these foods may be the cause. If you eat these foods without problems, the test adds little: a positive result is then no reason to leave something out of your diet.
For each food, the result shows whether you are sensitized: whether your body has made IgE antibodies. That is not the same as an allergy. Whether you are really allergic only becomes clear if the result fits a reaction to that food; in case of doubt, an allergist can do a food challenge.
A value above the cut-off for a food means that you have IgE antibodies against it. If that fits a reaction to that food, it is a likely cause. Positive results for foods you eat without symptoms are common, for example for soy due to cross-reaction with pollen, and in children the result for egg and milk often stays positive after the allergy has gone. The level of the value does not say how severe a reaction will be.
A value below the cut-off means that no IgE antibodies against that food were found; an IgE-mediated allergy is then less likely. With soy and wheat, and in young children with cow's milk, an allergy can still be missed. Lactose intolerance and celiac disease are not tested with this test.
Always discuss an abnormal result with your GP. If a result is strongly abnormal, we try to reach you as soon as possible. Read your result yourself as well and contact your GP if in doubt. A test does not make a diagnosis. Read more about risks and results

Practical information
After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
Often within a few working days. How soon you can be seen depends on how busy the location is and the type of analysis. For specialist analyses we first ship collection materials, which takes a bit longer.
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.
That depends on the test. Whether fasting is required, and from what time, is clearly stated in the instructions you receive after ordering. No surprises at the counter.
Usually within a few working days after collection. Turnaround time varies by analysis; analyses sent to an external lab can take longer. You receive your laboratory report securely by email. It lists the measured values, units, reference ranges and any flags added by the laboratory.
We work with 1,000+ collection points across the Netherlands. After ordering you'll see which locations near you are available and you pick where you'd like to go.

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!

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!
