Anaplasma phagocytophilum is a bacterium that grows in white blood cells and can reach people through a tick bite. The disease is called anaplasmosis and usually causes flu-like symptoms with fever, headache and muscle pain, which often go away after a few days. This test measures two types of antibodies against the bacterium: IgM and IgG.
With fever, headache or muscle pain in the weeks after a tick bite, if you want to know whether Anaplasma may be the cause. Anaplasmosis is rare in the Netherlands: the bacterium is found in 2 to 3 out of 100 ticks, but the disease is only diagnosed very occasionally. As a check after a tick bite without symptoms, the test is not useful.
In the first week of symptoms, the antibodies often cannot yet be detected. The result says most if the blood is drawn a few weeks after the symptoms start, and even more with a second test a few weeks later. With high or persistent fever after a tick bite, a doctor should see you; do not wait for this result.
The test shows whether your immune system has had contact with Anaplasma or a related bacterium. One result does not say when that was: IgG can remain detectable for months to years, and for this bacterium IgM is not a reliable sign of a recent infection.
A positive IgG means that you have had contact with Anaplasma or a related bacterium, such as Ehrlichia, at some point. A positive IgM may fit a recent infection, but is often wrong with this test. A recent infection only becomes clear from a clear rise in IgG in a second blood draw 2 to 10 weeks later, or from a PCR on blood in the first week of symptoms. Anaplasmosis is not notifiable in the Netherlands.
If IgG and IgM are both negative, a past infection with Anaplasma is less likely. Shortly after the symptoms start, the antibodies may still be absent, so a negative result in the first week does not rule out anaplasmosis.
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.

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.

“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!
