Everything you want to know

Choose a package on our website and click "Order". Enter your details and pay securely via Stripe (iDEAL, Klarna, Visa or Mastercard). You'll receive a confirmation email immediately.

We accept iDEAL, Klarna (pay later), Visa, Mastercard and other common payment methods via Stripe. All transactions are SSL-secured.

Administrative changes, such as your personal details or collection point, are free of charge as long as your request can still be adjusted.

If you cancel within 24 hours of your order and the laboratory request form has not yet been processed or sent, you receive a full refund of the purchase amount.

If you cancel after that, but before the blood draw, work has already been carried out, such as the medical review and processing of your request. In that case we charge €25 in administration and processing costs. The remaining amount is refunded via the original payment method.

After the blood draw, or after the statutory cooling-off period has expired, a refund is in principle no longer possible.

Would you like to cancel your order? Please contact us at support@bloodworks.nl and include your order or reference number.

If Bloodworks or the laboratory cannot provide the service and cannot offer a suitable alternative, you receive a full refund or you can choose a free new request. This does not apply where provision becomes impossible due to, for example, incorrect details or not following the laboratory's instructions.

Yes, you'll automatically receive an invoice by email after payment. Do you have a business account and want an invoice in your company name? Select the business invoice option at checkout.

Preventive blood tests not prescribed by a doctor are typically not tax-deductible. Consult your tax advisor for your specific situation.

For the most accurate results, we recommend 8 hours of fasting (no food, but water is fine). This is especially important for glucose and triglycerides. For packages without these markers, fasting is not required but recommended.

Bloodworks works with 800+ collection points across the Netherlands: GP practices, pharmacies and independent blood draw centres. You can visit a number of locations without an appointment. View all locations on our locations page.

Yes. After ordering and payment, you'll receive a lab form by email. Print it out or save it on your phone and bring it to the collection point.

We recommend at least 8 hours of fasting. A cup of water (no coffee, tea or juice) is allowed. You can take your medications as usual unless your doctor says otherwise.

Typically within 2 working days of your blood draw. For some specialist tests, the turnaround time can be up to 10 working days. As soon as all results are complete, you receive your report by secure email.

Your personal PDF report is sent by secure email. The report is written in plain language with a doctor's interpretation of each value.

Yes. Your report shows your values alongside the reference values used by the laboratory, including a doctor's explanation of what any abnormalities mean.

That is entirely your own choice: you have autonomy over your own data. We greatly value primary care. General practice is a wonderful and valued profession, but also a very busy one. That is why we try to relieve GPs and colleagues in primary and secondary care as much as possible, by having our medical team interpret your results as thoroughly as possible for you. However, we are not a treatment provider and we do not remove you from regular care. Sometimes the advice is to follow up on a particular value with your regular care provider; we handle this with great care.

Your report contains an interpretation of and advice on abnormal values. Where possible, we interpret and advise. Sometimes, however, further history taking, physical examination or additional testing is needed; we advise you on that too where necessary.

No. You can order directly without a referral. Bloodworks offers preventive blood testing on your own initiative.

Your report is interpreted by BIG-registered doctors with extensive experience in general practice, bariatric medicine, internal medicine and laboratory medicine, among other fields.

Bloodworks works exclusively with certified laboratories (ISO 15189) and BIG-registered doctors.
