Preventive blood test · Category 2 PGO
Legally required PGO information. Please read this and check the box to indicate your agreement before placing your order.
1. What is the purpose of this test?
This test provides insight into your testosterone levels without a doctor’s referral. It can serve as a starting point if you have questions about energy, libido, muscle building, or hormonal balance, and is also used to monitor hormone therapy or age-related changes.
The test does not replace a doctor and does not diagnose.
2. Is this test something for you?
This test is suitable for adults (18+) who:
Want to have their testosterone levels measured as a preventive measure or out of curiosity
Want to monitor their hormonal balance, for example, if they’re feeling tired or have low energy
Want to monitor hormone therapy or a lifestyle program?
People who are currently using or have used anabolic steroids and want this to be taken into account when interpreting their results
Are you pregnant or being treated for a serious medical condition? Please call us first. Our medical team will help you determine whether this test is appropriate for you.
3. How reliable is it?
The test is performed in an ISO-certified laboratory using the same methods as those used in hospitals. Testosterone levels fluctuate throughout the day due to the circadian rhythm; to ensure your results are comparable, we recommend having your blood drawn in the morning, between approximately 7:00 a.m. and 10:00 a.m.
What you’ve eaten, medications, a recent infection, or stress can also affect your levels. An abnormal result doesn’t automatically mean something is wrong. A normal result doesn’t rule out everything either. Our medical team will help you put the results in the right context.
4. How does the blood draw work?
Your blood will be drawn from a vein in your arm (venous blood draw) at one of the 1,000+ blood draw locations throughout the Netherlands. The blood draw is performed by a BIG-registered healthcare professional, or by someone who has been granted extended authority by a BIG-registered physician, who has determined that the healthcare professional is qualified and competent to perform this procedure.
For this test, you must fast: do not eat anything after 8:00 p.m. the night before the test, and drink only water.
Do you use anabolic steroids? If so, please mention this in the comments field during checkout. That way, if your results are elevated, we can follow up with you specifically to help you interpret the results correctly.
The risks associated with blood collection are minimal:
Sometimes a bruise or some pain at the puncture site, but this goes away quickly
Rarely, a feeling of lightheadedness or dizziness; this goes away on its own
Minimal risk of infection thanks to sterile materials and hygienic procedures.
Do you use blood thinners? Report that in advance at the lancing station.
5. What happens if something deviates?
If your results are abnormal, we’ll guide you through the process:
Do the results require immediate medical follow-up? If so, we’ll call you personally before you see the results online.
Do you have questions about an abnormal value? Contact our medical team. They will explain the results and work with you to determine the best next step.
Would you like to discuss your results in detail? Through our Extra Services you can request a consultation with one of our doctors or health coaches.
We do not diagnose or give treatment advice. We do help you find the right way.
6. And if something unexpected comes out?
A testosterone test is a targeted test, but even here, a result can sometimes prompt additional attention that you didn’t expect—for example, if a value falls significantly outside the expected range. We call this an incidental finding. We always inform you of this in your test results. Our medical team can help you determine whether further steps are necessary.
7. Can this be relevant to my family?
Some conditions associated with abnormal testosterone levels, such as PCOS, may have a genetic component. If your results show anything unusual, it may be helpful to discuss this with first-degree relatives. Our medical team can advise you on the significance of the findings. We recommend discussing this with your primary care physician for inclusion in your medical record and for any necessary guidance for first-degree relatives.
