7 values instead of one number

Finally, clarity instead of guesswork: Only 1–2% of your testosterone is free and therefore usable by your body – the rest is bound to transport proteins such as SHBG and albumin. A total testosterone level in the “normal range” can therefore be misleading: If SHBG is elevated, for example, too little effective testosterone remains. Our premium test therefore measures 7 relevant laboratory values: total and free testosterone, SHBG, albumin, free androgen index, LH and PSA, analyzed in a certified German partner laboratory.

This gives you the complete picture, not just a single data point.

Important: Our test kits are suitable exclusively for men. The tests themselves do not constitute a diagnosis or therapy. Whether treatment is carried out is solely the responsibility of the treating physicians.

Independent partner doctors who take you seriously

If you wish, specialized doctors will review your levels and symptoms together with you—without being dismissed or pressured to justify yourself. Together with the independent doctor, you decide how to proceed and whether a treatment (e.g., TRT if medically indicated) can be started; no one will pressure you into treatment.

Possible symptoms of testosterone deficiency:

  • Constant fatigue, even after enough sleep
  • Lack of motivation: things that used to be easy for you now take effort
  • Poor sleep despite tiredness
  • Irritability or low mood
  • Less interest in sex, less frequent morning erections
  • Less strength and muscle loss despite training

Blood draw from the upper arm instead of a finger prick: Tasso blood collection device worth €19.90 included.

With the Tasso device, you can easily collect your sample at home. You place it on your shoulder or upper arm, press a button, and the device collects the blood in a vial itself.

Advantages:

  • No finger pricks, no squeezing. You don't have to squeeze blood from your finger.
  • Sufficient sample volume, even for multiple tests. 
  • Fewer errors during collection. The device takes care of the most difficult part.
  • For anyone who doesn't like needles. You won't see the lancets.
Note: Prefer a classic approach? Alternatively, you can order the test with lancets for a finger prick.

Men share their experiences with Adon Health

Excellent 4.6 / 5

Because a number alone is not an answer. 

Our test measures seven relevant values, including free testosterone and SHBG, analyzed at the certified German partner laboratory. Blood collection at home in just a few minutes, results in 3–5 business days: no appointment, no travel, no waiting room.

Total testosterone

The total amount of testosterone in your blood – bound and free. The starting point for any assessment, but not an answer in itself.

SHBG

The protein that binds testosterone in the blood, thereby determining how much of it is available to exert its effects. If SHBG is too high or too low, your total testosterone level may appear "normal" even though your body does not have enough available.

Free testosterone (calculated)

The unbound fraction that actually reaches your cells. This is usually the crucial value—calculated from total testosterone, SHBG, and albumin.

LH (Luteinizing Hormone)

The regulatory hormone from the brain that stimulates testosterone production in the testicles. It can show where the cause of a low level lies – in the testicles or in the regulation. Also important when it comes to fertility.

Albumin

The second transport protein for testosterone – necessary to precisely calculate your free testosterone. It also provides an indication of liver and nutritional status.

Free Androgen Index (FAI) (calculated)

The ratio of testosterone to SHBG. Particularly helpful when total testosterone alone does not provide a clear picture.

PSA

The marker for your prostate health. Good to know – and medically important before any therapy is even considered.

The Adon Certainty Guarantee

A blood test is a matter of trust. And trust is earned not with promises, but with commitments we stand by. That is why we triple-guarantee your first test:

1. Replacement kit guarantee: Your sample counts – or we repeat it free of charge.
Not every capillary blood sample is successful the first time. If your sample cannot be analyzed in the lab – for whatever reason – we will send you a new test kit free of charge. No questions asked, no additional costs.

2. 14-day money-back guarantee.
Change your mind? Cancel within 14 days and receive a full refund.

3. 3-day doctor's consultation guarantee.
Certainty should not have to wait. If you would like to book a doctor's consultation after receiving your results (optional, for a fee), you will get your appointment with one of our independent partner doctors within 3 business days – instead of waiting weeks in the waiting room.
