Value package · For the active athlete

Bloodworks Sport

A focused sports panel with the markers that matter for performance and recovery: iron status, electrolytes, muscle recovery (CK), metabolism and the hormones behind recovery and balance. All-in, including blood draw and collection costs.

Bloodworks Sport is a blood test measuring 19 biomarkers across 6 measurement domains, reviewed by a doctor. Below you see exactly what is measured and what those results tell you.

Who is this package for?

Recreational athlete

Training three or more times a week? Bloodworks Sport combines a full base check with the markers behind your performance and recovery.

Track performance and recovery

Iron status, testosterone, cortisol and CK show whether your training load and recovery are in balance, often before you feel it in your performance.

Unexplained fatigue

Less energy or disappointing performance? Iron, ferritin, vitamin D and B12 are among the first things to check.

Start of a training block

Set a complete baseline before a new training period, covering both your general health and your sport-specific markers.

FAQ

Frequently asked questions

How long does it take to get my results?

Typically within 2 working days of your blood draw. Some vitamins and minerals take longer, these values are almost always available within 5 business days. You receive an email as soon as your report is ready.

Do I need to fast?

Yes, we advise fasting for 8 hours for the most reliable result, particularly for glucose and triglycerides.

Where can I have my blood drawn?

Bloodworks works with more than 1000 collection points across the Netherlands. You choose your location yourself after ordering.

Do I need a referral?

No, you can order directly without a referral from your GP.

Can I share my report with my GP?

Yes, your report is written in medical language and contains all relevant laboratory information. Many customers take it to a consultation.

Are the blood draw and collection costs included?

Yes. At Bloodworks you pay a one-off €29 in blood draw and collection costs per order, and from €225 that amount is waived. This value package is priced above that, so you pay nothing extra for the collection point or the blood draw. If you order only a smaller theme package or a single marker, the €29 is added.
