Hormones Man

Testosterone does not act in isolation. SHBG and Albumin determine how much testosterone is actually available to tissues. Measuring all four markers together may reveal imbalances that a single testosterone reading could miss, giving a broader view of male hormonal balance.

This test may be relevant for:

• Men who want a broader understanding of their hormonal profile
• Those curious about the interplay between binding proteins and testosterone
• Men experiencing changes in energy, body composition, or recovery that could be related to hormonal factors

• Total Testosterone (nmol/l, ref: 8.64-29): the combined amount of bound and unbound testosterone in the blood.
• Free Testosterone (pmol/L, ref: 170-700): the unbound fraction, calculated from the other three markers.
• SHBG (nmol/l, ref: 18.3-54.1): sex hormone-binding globulin, a protein that binds testosterone tightly and reduces its availability.
• Albumin (g/l): a protein that loosely binds testosterone and is used in the Free Testosterone calculation.

These markers work as a system. SHBG levels can shift due to age, body composition, or other factors, and those shifts may affect how much testosterone reaches your tissues. For example, two men with identical Total Testosterone values could have very different Free Testosterone levels depending on their SHBG. This panel may help uncover those differences and provide a more nuanced picture of hormonal status.

A blood sample is drawn at a certified sample point (afnamepunt). There are over 750 locations across the Netherlands. The procedure typically takes around 10 to 15 minutes. After placing your order, you can select a location and time that works for you.

This panel may be useful when you want to understand how your hormones relate to each other, not just whether a single value falls within range. It can also be relevant when experiencing fatigue, reduced drive, or shifts in body composition that could have a hormonal component.

Results are presented with reference ranges for each marker. Because these markers influence each other, individual values should be considered together rather than in isolation. A healthcare provider can help interpret the overall pattern and determine whether any findings warrant further evaluation.

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

Your results are available in your personal dashboard, presented in a clear report with reference ranges for each marker. If any values fall outside the expected range, or if you have questions about what the results may mean, discussing them with a healthcare provider is recommended.
