01 Why

Why without a referral?

Not everyone has symptoms. But anyone who wants to follow their health proactively shouldn't need to go through the GP for it, and people who do have symptoms can often get a broader picture from a private test than from a typical referral.

With Optimize you decide what to measure, when and where. No waiting for a referral, no justification up front.

02 How

How does this work legally?

Private blood testing is fully legal. Optimize works with certified labs and draw locations; the results are medically valid and based on the same standards as hospital laboratories.

You pay directly, no claim goes to your insurer, and it does not count towards your deductible.

03 Next

What if values are off?

The Optimize app gives context per marker: the lab's reference range, where you stand and what that means, but Optimize does not diagnose or treat.

For significantly off values we recommend talking to your doctor. You can share the app's report as an attachment, that gives your doctor your full blood picture rather than a single value.
