What is Keto Diet Blood Test?

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.

What is tested?

  • Cholesterol (total) – Total cholesterol in the blood
  • HDL cholesterol – "Good" cholesterol that removes excess cholesterol
  • LDL cholesterol – "Bad" cholesterol that can accumulate in blood vessels
  • Triglycerides – Fats in the blood
  • Glucose – Blood sugar level
  • HbA1c – Average blood sugar over the past 2-3 months

Why should you get a Keto Diet Blood Test?

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.

What does it indicate?

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.

What does a high level mean?

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.

What does a low level mean?

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.

Frequently asked questions

Answers to what people usually want to know.

How does it work from order to result?

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.

How quickly can I get tested?

Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.

Do I need to book an appointment?

At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.

Do I need to fast before the test?

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.

When and how do I receive my result?

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 get an email with a link to your digital result, including a short explanation per value.

Where can I go for collection?

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.
