Blood test in Leiderdorp.

Yes, Winkelhof takes walk-ins. 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 Leiderdorp location and a time slot in the Optimize app.

You draw at a location run by SCAL or Atalmedial, 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 16 locations in and around the village: at the de Florijn health centre and at the Alrijne hospital on the Simon Smitweg, and beyond that in Leiden at De Singel, the Merenwijk, the Rooseveltstraat, the Poortgebouw, the Leidse Hout, the Alrijne Leiden and the Stevenshof, in Oegstgeest, Warmond and Hazerswoude-Rijndijk. All addresses are on this page, sorted by distance.

Yes. In Leiden you draw at De Singel on the Lusthoflaan, in the Merenwijk or at the main location on the Rooseveltstraat, in Oegstgeest at Actea, the Poelgeest practice or MC Oegstgeest. 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 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.
