Blood test in Nieuwegein.

Yes, at 7 of the 19 locations in and around Nieuwegein you can walk in, including Zorgplein Zuid Ratelaar, De Ratelaar and Wijk Service Centrum De Oase. 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 Nieuwegein location and a time slot in the Optimize app.

You draw at a location run by Saltro or Star-shl, but 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.

At 19 locations in and around the city: at the Boogstede, Batau, the Roerdomp, the Componist, the Schans, Zorgplein Zuid and Galecop, and beyond that in IJsselstein, Vianen, Hoef en Haag, Houten and Utrecht-Zuid. All addresses are on this page, sorted by distance.

Yes. In IJsselstein you draw at 't Kruispunt on the Touwlaan or at Nieuwpoort on the Jan van der Heydenweg, in Utrecht at Kanaleneiland on the Beneluxlaan or in Hoograven. In the app you simply pick the address that suits you best; the lab and the results are the same everywhere.

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. The app tells you exactly how to prepare.

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