Blood test in Zoetermeer.

No, in Zoetermeer you draw at a time slot you schedule in the Optimize app. The nearest walk-in is De Leeuwerik in Bleiswijk, 6 km away; there you pick a one-hour arrival window in the app and confirm you are coming.

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

You draw at a location run by SCAL, 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 Medisch Centrum Zoetermeer on the Hannie Schaftrode 142 in Buytenwegh, a five-minute walk from the RandstadRail stop. It is the city's permanent draw point; the nearest other addresses are in Leiderdorp, Leiden and Voorschoten, a quarter of an hour's drive away.

Yes. In Leiderdorp you draw at the Alrijne hospital on the Simon Smitweg or at the Florijn, in Leiden at De Singel or at the main location on the Rooseveltstraat. 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 SCAL is done, your results appear in the Optimize app, explained per value in plain language and translated into what it means for your lifestyle.
