Blood test in Haarlem.

Yes, at 6 of the 19 locations in and around Haarlem you can walk in, including William Harvey, GC Schalkwijk and Ons Tweede Thuis. 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 Haarlem location and a time slot in the Optimize app.

You draw at a location run by Atalmedial or SALT, 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 twelve locations in and around the city: in Noord at the Immanuelkerk and the Spaarne Gasthuis Noord clinic, on the south-west side at the de Koningin health centre, in Schalkwijk at the Spaarne Gasthuis Zuid, and beyond that in Bloemendaal, Spaarndam, Velserbroek, Vijfhuizen, Halfweg, IJmuiden and Hoofddorp. All addresses are on this page, sorted by distance.

Yes. The Bloemendaal GP centre on the Dennenweg and MC de Sluis in Spaarndam are a few kilometres from the centre, and in Hoofddorp you draw at the Spaarne Gasthuis clinic or at MC Toolenburg. 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 Atalmedial is done, your results appear in the Optimize app, explained per value in plain language and translated into what it means for your lifestyle.
