Common Questions

Frequently Asked Questions

About performance 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. Most athletes want markers tested that aren't part of a standard blood panel.
Standard blood tests focus on symptoms and are limited to a basic blood count. Markers like testosterone, IGF-1, or SHBG typically aren't included. With Enhancedhealth, you choose which markers to measure, whenever you want.
Yes, significantly. Intense training temporarily raises CRP (inflammation) and CK (muscle breakdown) by 200-500%. Testosterone may drop after heavy sessions. Schedule your blood draw on a rest day, at least 24-48 hours after your last intense workout.
Most markers (testosterone, CRP, iron, thyroid) 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.
For most athletes, quarterly is optimal. It lets you track trends across training cycles (build, peak, recovery). For specific goals like a cut, bulk, or competition prep, monthly testing can be valuable.
There's almost always a blood test location near you: 700+ certified labs across the Netherlands. Most people have a lab within 10 minutes. Tip: schedule early morning. Fasting blood gives more accurate results for testosterone, glucose, and lipids.
Yes. Your Enhancedhealth dashboard shows all measurements in trend charts. Compare testosterone, CRP, iron, and other markers across training cycles. Objective data instead of guesswork.
The essentials: testosterone (anabolic status), CRP (systemic inflammation), ferritin (iron stores), thyroid (metabolism), and vitamin D (bone and immune function). Browse our panels page to choose.
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.
