Value package · Medical weight loss & GLP-1
Bloodworks Weightloss
The full Bloodworks Plus base check combined with the nutritional and metabolic markers that matter during medical weight loss or GLP-1 medication (such as Ozempic or Wegovy). All-in, including blood draw and collection costs.
Bloodworks Weightloss is a blood test measuring 30 biomarkers across 8 measurement domains, reviewed by a doctor. Below you see exactly what is measured and what those results tell you.
Who is this package for?
Starting a GLP-1 programme
About to start GLP-1 medication (such as Ozempic or Wegovy)? A complete baseline gives you a reference point for your sugar, liver, lipid and nutritional values.
Follow-up during weight loss
After a few months your sugar, liver and lipid values change. A repeat measurement makes that progress concrete.
Protect your nutritional status
Eating less depletes ferritin, B12 and vitamin D faster. This way you see in time whether supplementation makes sense.
Losing weight without medication
On a calorie-restricted diet or lifestyle programme, your metabolic and nutritional markers are just as worth tracking.

FAQ
Frequently asked questions
How long does it take to get my results?
Typically within 2 working days of your blood draw. Some vitamins and minerals take longer, these values are almost always available within 5 business days. You receive an email as soon as your report is ready.
Do I need to fast?
Yes, we advise fasting for 8 hours for the most reliable result, particularly for glucose and triglycerides.
Where can I have my blood drawn?
Bloodworks works with more than 1000 collection points across the Netherlands. You choose your location yourself after ordering.
Do I need a referral?
No, you can order directly without a referral from your GP.
Can I share my report with my GP?
Yes, your report is written in medical language and contains all relevant laboratory information. Many customers take it to a consultation.
Are the blood draw and collection costs included?
Yes. At Bloodworks you pay a one-off €29 in blood draw and collection costs per order, and from €225 that amount is waived. This value package is priced above that, so you pay nothing extra for the collection point or the blood draw. If you order only a smaller theme package or a single marker, the €29 is added.
