The Keto Diet Blood Test is specially developed for individuals following a ketogenic diet or considering starting one. On a keto diet, you eat extremely few carbohydrates and many fats, causing your body to enter ketosis and use ketones as fuel instead of glucose. This diet can cause significant changes in your cholesterol levels and blood sugar. This test measures the most important values that can change due to the keto diet and helps you monitor metabolic adaptations.
The ketogenic diet has a significant impact on your metabolism and can have both positive and negative effects on your cholesterol and blood sugar levels. For some people, the lipid profile improves dramatically, while for others, LDL cholesterol can rise sharply. This test is essential to check if the keto diet is safe for your body. It is recommended to do this test before starting keto to establish a baseline, and then periodically every 3-6 months to monitor the effects. Especially people with a history of high cholesterol or cardiovascular disease should closely monitor their values.
The results show how your body reacts to the ketogenic diet. A decrease in glucose and HbA1c indicates that your blood sugar regulation is improving, which is particularly beneficial for people with insulin resistance or type 2 diabetes. Changes in the lipid profile provide insight into your cardiovascular health. Decreasing triglycerides and increasing HDL are positive signs. The LDL value is complex: some people experience an increase that may be harmless, but this needs to be monitored.
Elevated total cholesterol and LDL cholesterol can occur with keto, especially in the first months of adaptation. For some people, this stabilizes over time, but for others, it remains elevated. A strongly elevated LDL requires further investigation into LDL particle size and possibly dietary adjustments (more unsaturated fats, fewer saturated fats). Elevated glucose or HbA1c during keto should not occur and may indicate insufficient adherence to the diet or other underlying problems.
Low glucose and HbA1c values are usually positive and show improved blood sugar regulation and insulin sensitivity. Low triglycerides are excellent and a common positive effect of keto. Too low HDL cholesterol is undesirable and may indicate insufficient healthy fats in the diet. Very low glucose can sometimes indicate insufficient carbohydrate intake or hypoglycemia, especially in people taking medication for diabetes. These values help you optimize your diet for maximum health benefits with minimal risks.
This test is included in Dutch healthcare guidelines and is regularly used for its respective indications.
Rationale for this test
Dit pakket bevat standaard bloedwaarden die in Nederlandse zorgrichtlijnen worden gebruikt voor monitoring van cholesterol, bloedsuiker en diabetes. Alle componenten (totaal cholesterol, HDL, LDL, triglyceriden, glucose en HbA1c) zijn gevestigde diagnostische markers met sterke wetenschappelijke onderbouwing. Deze waarden zijn relevant voor mensen die een ketogeen dieet volgen, omdat dit dieet significante veranderingen in lipiden- en glucosemetabolisme kan veroorzaken.

We recommend consulting these independent sources before ordering a preventive health check.
Brochure on preventive health checks: careful choice, reliability, pros and cons, checklist.
Independent information about preventive health checks from the National Institute for Public Health and the Environment.
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.

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!
