Frequently asked questions

Under the Dutch quality standard for preventive health screening (NEN 8051:2023 §7.7) we ask for your explicit consent and a few choices per order.

An incidental finding is a result that falls outside your original question but may still be medically relevant. You decide whether you want to be informed about clinically relevant, treatable incidental findings and about findings that may affect your offspring.

Your choices are recorded together with the date and the version of our terms in your client record. For background see our incidental findings page.

You have the right not to be informed about certain outcomes. That applies for example to serious, non-treatable incidental findings: we do not share those with you as a rule.

For clinically relevant, treatable incidental findings and for findings affecting offspring, you record your preference at checkout.

In exceptional situations the involved BIG-registered doctor may still feel obliged to report, based on conscience, for example in case of serious danger. See also our incidental findings policy.

For genetic tests (such as Factor V Leiden and Hemochromatosis) and tests with increased risk we require a written referral from a BIG- or AGB-registered doctor or therapist (name, registration number and a brief motivation).

This ensures the result can be interpreted well and that you receive guidance on next steps. You place the order online as usual; we then contact you to align the referral.

Our laboratory (Medizinische Laboratorien Dr. Stein + Kollegen) operates under German law and is required under the Gendiagnostikgesetz (GenDG) to receive a signed consent declaration for every genetic determination.

In the form you confirm among others: that you have been informed about the purpose, scope and risks of the test, that you have the right to withdraw consent, that you are entitled to independent genetic counselling, and that the result is reported back via your doctor.

The form is included with the test kit and can also be downloaded in advance: consent form (PDF). This is separate from the general consent at our checkout; it is an additional laboratory requirement, specific to genetic testing.

Preventive health screening (PGO) is divided into three categories as described in the Dutch quality standard NEN 8051:2023 and the NVvPG client brochure.

Category 1: simple self-tests you carry out and read yourself, such as a pregnancy test. These fall outside NEN 8051 and we do not offer them.

Category 2: tests where blood is drawn at a sampling location or where a laboratory gives a medical interpretation — think of cholesterol, thyroid, hormones, vitamins, certain genetic tests such as Factor V Leiden. Strict quality requirements and a consent declaration under NEN 8051 §7.7 apply. Almost our entire range falls in this category.

Category 3: licensed population screening under the Dutch Population Screening Act (Wbo art. 2). This includes research aimed at detecting cancer, research using ionising radiation, and research into serious conditions for which no treatment or prevention exists. Examples: tumour markers (CEA, CA-125, Chromogranine A), HPV screening, iFOBT bowel cancer screening and DNA panels for hereditary cancer. We do not offer these because we do not hold a Wbo licence.

Note: the formal law that would codify this classification (bill 35384) was withdrawn in January 2025 in favour of a new proposal. The classification is therefore a field standard via NEN 8051 and is applied unchanged by the Dutch Healthcare and Youth Inspectorate.

No. Research aimed at detecting cancer is subject to licensing under the Dutch Population Screening Act (Wbo art. 2). Because we do not hold a Wbo licence we do not offer these tests as preventive screening.

Your GP or a medical specialist can request these tests on a specific clinical indication.

PSA is a marker that can help evaluate prostate-related complaints. For men without complaints the Dutch NHG (College of General Practitioners) and the Health Council do not recommend PSA as screening, because it can lead to follow-up tests and treatment you would otherwise not have had.

PSA is however useful with urinary complaints, a previously elevated value, or a familial background. Please discuss PSA testing with your GP first.

We keep your results and consent declaration for 20 years in a secure client record, in line with the Dutch Medical Treatment Agreement Act (WGBO art. 7:454) and the GDPR.

Administrative data follows statutory retention periods. See our privacy statement for details on what data we process and for how long.

For access, correction or deletion requests please email info@bloedcheckup.nl.

For complaints about our care we follow the Dutch Healthcare Quality, Complaints and Disputes Act (Wkkgz).

You can first contact us directly; if we cannot resolve it together you can turn to our independent complaints officer and disputes body.

See our complaints procedure for the full process and timelines.

For a number of infectious diseases there is a statutory obligation to notify the municipal health service (GGD) under the Dutch Public Health Act (Wpg). On a positive result we and the laboratory are required to share your personal details with the local GGD for source and contact investigation. Anonymity is then not possible.

This includes certain STIs (such as HIV, syphilis, specific forms of gonorrhoea), hepatitis B and C, and a number of other infectious diseases. Nothing is shared on a negative result.

Which tests fall under the notification obligation and what exactly happens on a positive result can be found on our page notifiable infectious diseases.

Under the General Data Protection Regulation (GDPR) you have among others the right of access, correction, deletion (as far as not legally required to retain), restriction of processing, data portability and objection to certain processing.

The right to deletion is limited for medical data: under the Dutch WGBO (art. 7:454) we are required to keep your client record for 20 years. After that period we destroy the data.

For a request you can email info@bloedcheckup.nl. We reply within the statutory period. See our privacy statement for details.
