Ordering & Account
Do I need a referral from my GP?
No, you don't need a referral from your GP. You can order a blood test directly online. However, we recommend always contacting your GP if you have doubts about results.
From what age can I order a test?
You must be at least 18 years old to order a blood test yourself. For minors, permission from a parent or guardian is required.
Can I combine multiple tests?
Yes, you can combine different tests in one blood sample. This is efficient and you only need to have blood drawn once for all desired examinations.
Is my test kit shipped discretely?
Yes, all test kits are shipped completely discretely in neutral packaging without any reference to blood tests or medical content. The sender on the package is listed as 'D3V B.V.', so it's not immediately visible that it's a blood test.
Testing & Preparation
Do I need to fast for all tests?
No, most tests don't need to be performed fasting. Only for specific tests like Homocysteine, HOMA IR and Bone enzyme is 12 hours of fasting required.
