Blood tests near you.

Yes, at 120 of the 360 locations you can walk in, most of them in Amsterdam (27), Purmerend (8) and Zaandam (7). There too you pick a one-hour arrival window in the Optimize app and confirm you are coming, so the lab expects you. The other locations draw at a time slot you schedule in the app.

No. You start online yourself, without a GP referral, and then pick a location and a time slot in the Optimize app.

At a location run by Atalmedial, Saltro, SALT, Medlon, SHO or SCAL, the labs GPs work with too. You schedule and pay through Optimize, without a referral, and your results come with explanations in the Optimize app. Have a referral from your GP? Then you make the appointment with the lab itself and the results go to your GP.

Not automatically. You draw without a referral, so your GP need not be involved: your results come with explanations in the Optimize app, and you can always take them along to a consultation yourself.

Yes. Every draw is fasted: nothing to eat or drink from midnight, only water. Appointments are therefore in the morning, until 12:00. So you only postpone breakfast, and the app tells you exactly how to prepare.

Usually within 24 hours of your draw. As soon as the lab is done, your results appear in the Optimize app, explained per value in plain language and translated into what it means for your lifestyle.
