The Comprehensive Fatigue blood test is an extensive test that goes beyond the basic package and specifically looks at inflammation and complete blood counts. This test is suitable for people with severe or long-lasting fatigue that does not improve, or when the basic package did not provide a clear explanation. In addition to all basic tests, erythrocyte sedimentation rate (ESR) and a complete blood count (CBC) are added to detect active inflammation, infections, and blood disorders that can cause fatigue.
This test is important when your basic fatigue test results were normal but you are still very tired, or when, in addition to fatigue, you have other symptoms such as fever, weight loss, night sweats, or painful joints. The ESR (sedimentation) is a sensitive marker for inflammation and can indicate autoimmune diseases, infections, or other inflammatory conditions. A complete blood count shows whether there are problems with white blood cells (infections, immune disorders) or platelets. Ferritin is more sensitive than serum iron for detecting iron deficiency. This test requires fasting.
The results provide deeper insight into possible causes of persistent fatigue. This comprehensive test measures:
This extensive analysis also helps detect rarer causes of fatigue.
The advantage of this comprehensive package is that underlying inflammation and blood disorders, which might otherwise be missed, are also detected.
Haemoglobin, haematocrit, erythrocytes, MCV, MCH, MCHC, leukocytes and platelets.
This test is included in Dutch healthcare guidelines and is regularly used for its respective indications.
Rationale for this test
Dit pakket combineert standaard-diagnostiek voor vermoeidheid zoals opgenomen in Nederlandse zorgrichtlijnen. De NHG-richtlijn SOLK en de CVS-richtlijn benoemen BSE/CRP, bloedbeeld, schildklierfunctie, glucose en ijzerstatus als onderdeel van de diagnostische work-up bij langdurige vermoeidheid. Alle componenten zijn gevestigde laboratoriumbepalingen met duidelijke klinische betekenis.

We recommend consulting these independent sources before ordering a preventive health check.
Brochure on preventive health checks: careful choice, reliability, pros and cons, checklist.

Reliable patient information about illnesses and complaints from Dutch GPs (NHG).
Public-facing website of the Dutch Society for Clinical Chemistry with explanations of blood tests and laboratory values.
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.
It varies per analysis: from same-day to a few working days. Standard values often come back quickly; analyses that go to an external lab can take a bit 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.

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!

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!
