How much does a blood test cost?

A single blood test starts at €49. Core membership is €365 per year (€1 per day), billed once, with a blood test every year. You can extend any test with add-ons, and the Optimize app is free to download.

Is it reimbursed by my health insurance?

Private, preventive blood testing is generally not reimbursed by basic Dutch health insurance; you pay for it yourself. Some supplementary policies reimburse part of it. Check your policy.

Where are the draw locations?

You can get tested at 250+ draw locations in North Holland, South Holland, Utrecht, Flevoland, Gelderland and Overijssel. Living in Brabant, Limburg, Zeeland or the north? We're working on it, with the aim of covering the whole country by the end of 2026.

Your data is encrypted, stored in the EU under GDPR, and never sold. Our security follows ISO 27001 / NEN 7510 and blood samples are processed by ISO-accredited Dutch laboratories. You can export or delete your data any time, and you decide who to share it with.
