Frequently Asked Questions

About men's blood testing, the process, and what to expect.

No. You order your blood test directly online. We arrange the lab referral via ZorgDomein. No referral needed, no waiting list. You can go to the lab the same week.
Standard blood tests typically only include testosterone with serious symptoms, and a referral can take months. With Caliberhealth, you order today and have results within a few business days.
Testosterone peaks early morning and drops by 20-30% throughout the day. Schedule your blood draw between 7:00 and 10:00 AM for the most representative value. Fasting is not required, but recommended for more accurate lipid and glucose readings.
Most hormone values are available within a few business days. In some cases, certain markers may take longer. We'll let you know as soon as they're ready.
From your 30s, testosterone drops by an average of 1-2% per year. That doesn't automatically mean a problem, but symptoms like fatigue, reduced libido, or concentration issues may indicate a deficiency. A blood test gives you an objective starting point.
Fully. Your results are encrypted and only accessible with your login credentials. Never shared with your GP, employer, or insurer. Your bank statement shows a neutral description.
There's almost always a blood test location near you: 700+ certified labs across the Netherlands. Just regular phlebotomy points. Most people have a lab within 10 minutes. Most visits take under 15 minutes.
Total testosterone measures all testosterone in your blood. Free testosterone is the portion your body can directly use. Both values matter: a normal total with low free T can still cause symptoms. Our hormone panel measures both.
We create a lab referral via ZorgDomein. On the same business day you receive an email with a barcode. Orders outside business hours are processed the next business day. If we need more information from you, we will contact you. You can visit the lab at any time.
Two things: a valid ID and the barcode from your ZorgDomein email (showing it on your phone is fine). The lab staff handles the rest. No BSN? Print the referral form from the ZorgDomein patient portal.
Depends on the location. Some labs accept walk-ins, others require an appointment. You'll see this when choosing your lab location, and we'll provide a booking link if needed.
