All blood tests.

You only notice something once your body can no longer absorb a change. A value can shift slowly for years without any symptoms. Your blood shows that shift earlier, while it is still easy to correct. The first test shows where you stand now. Every test after that shows whether what you changed is working.

More than whether a value falls within the reference range. Where it sits in that range matters too: at the edge or in the middle. At your next test you also see which way it is moving. That shows what is going well and what needs attention, before it turns into a complaint. In the app, every value is explained in plain language: what it measures and what it means.

Do you have a specific question, for example about fatigue, hormones or your heart? Then pick the test for that. Want the complete picture? Then pick the comprehensive test. Not sure? Start with the comprehensive test. You can add a focused test to the same draw.

Yes, all tests go into one blood draw. If two tests measure the same value, you pay for it once. An extra test only costs what it adds.

No. You order online and then book your own appointment at one of 600+ draw locations in the Netherlands. Your blood is analysed in laboratories accredited to ISO 15189.

Usually within 24 hours of your blood draw. Your results are in the Optimize app, with every value explained in plain language.

A single test is one measurement you pay for once. Core membership runs for a year and costs €365 a year, in one payment. You get the blood test with 60 values and your biological age. You also get the app with weekly plan and AI coach.

Yes, in the app, as long as you have not booked your appointment yet. The extra test then goes into the same draw. Once your appointment is booked, that is no longer possible. A test you want after that gets a draw of its own.
