Blood test in Woerden.

Yes, at 2 of the 4 locations in and around Woerden you can walk in, including Gezondheidscentrum Woerden and Kerkelijk centrum Het Trefpunt. 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 time slot at the Iepenhof 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 the Iepenhof on the Iepenhof 1, in the middle of town a ten-minute walk from the station. It is Woerden's permanent draw point; the nearest other addresses are in De Meern, Vleuten and Leidsche Rijn, a quarter of an hour's drive away.

Yes. On the west side of Utrecht you draw at the Molenpolder in De Meern, Vleuterweide in Vleuten or Rijnvliet in Leidsche Rijn, in Alphen at the Alrijne hospital or the Dillenburg health centre. 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.
