Good to know

Benefits and limitations of blood testing

A blood test offers valuable insight into your health, but it also has limitations. We set out both honestly, so you can make a well-considered choice.

Benefits

  • Early signals: deviations can become visible before you notice symptoms.
  • A complete picture in one draw: key values clearly together.
  • Interpreted by a doctor: you get context with your results, not just numbers.
  • Track your health over time: repeat easily and see changes.
  • Accessible: no referral needed, a draw at 800+ locations.

Points to consider

  • An abnormal value does not always mean something is wrong; sometimes it is normal for you or a recheck is needed.
  • A normal result does not rule out every condition.
  • Some findings may lead to unnecessary worry or follow-up testing.
  • A blood test is a snapshot in time and does not replace a medical diagnosis.
  • Do you have symptoms or doubts? Always discuss these with a doctor.

We value honest information. For independent information on the benefits and limitations of health tests, we are glad to refer you to the Dutch RIVM, pros and cons of health tests.

Veelgestelde vragen

Alles wat u wilt weten

Do I need to fast?

Fasting is not required for hormones, but we recommend having your blood drawn in the morning between 7 and 10 o'clock, testosterone is at its highest then and most suitable for interpretation.

What is the difference between total and free testosterone?

Total testosterone measures all testosterone in the blood. Free testosterone measures the active, unbound fraction. SHBG partly determines the ratio between the two. The combination gives a more complete picture than total alone.

What if I take testosterone medication?

With testosterone replacement therapy, the values mainly reflect the medication. Please let us know so we can adjust the interpretation accordingly.

Is this package suitable for women?

No, this package is designed for men. For women, the Essential Hormones Female package is available.

What if my values are abnormal?

Our doctor provides explanation and context for your result. You can use the report for your own insight or bring it to conversations with your GP.

What if I want to measure more specific markers?

Through Bloodworks Select you can add additional markers such as DHEA-S, oestradiol, or cortisol.

How does this relate to a PSA test?

This package measures hormones, not PSA. For PSA monitoring (often relevant from age 50+), you can add PSA as a separate marker or consider a broader men's health package.

How quickly do I receive my results?

Typically within 2 business days of blood draw, you will receive your report by email.
