Hormones Man

Testosterone plays a role in energy, mood, muscle maintenance, and general wellbeing. However, the total amount of testosterone in the blood does not tell the full story. A portion is bound to proteins like SHBG and is not readily available to the body. This panel measures both Total and Free Testosterone to provide a more complete picture.

This test may be relevant for men who are curious about their hormone levels, for example when experiencing changes in energy, mood, or physical vitality. It can also serve as a baseline for those who simply want to know where they stand.

• Total Testosterone (nmol/l): the overall level of testosterone in the blood, including both bound and unbound forms.
• Free Testosterone (pmol/L): the portion not bound to SHBG or Albumin, representing the bioavailable fraction.
• SHBG (nmol/l): Sex Hormone-Binding Globulin, a protein that binds testosterone and influences how much is freely available.
• Albumin (g/l): a blood protein that loosely binds testosterone; used in the calculation of Free Testosterone.

The results may show whether your testosterone levels and bioavailability fall within expected ranges for your age group. For example, it is possible to have a normal Total Testosterone but lower Free Testosterone if SHBG is elevated. Seeing these markers together provides more context than a single testosterone measurement alone.

A blood sample is drawn at a certified sample point (afnamepunt). There are over 750 locations across the Netherlands. After placing your order, you can select a location and time that suits you.

This test may be useful when you want insight into your hormonal balance, for example as part of a general health check or when changes in how you feel prompt curiosity about your hormone levels.

Results are presented with age-appropriate reference ranges. Hormone levels naturally vary between individuals and can be influenced by factors such as sleep, stress, and overall health. A healthcare provider can help you understand what your values may mean in the context of your personal situation.

Fasting is recommended for more consistent results. Testosterone levels tend to be highest in the early morning, so testing between 7:00 and 10:00 AM is advised.

Your results are available in your personal dashboard. If you have questions about the values, or if any results fall outside the reference range, discussing them with your healthcare provider is recommended.
