Body-Balance Check | Testosteron-Test: which blood markers matter?

For a meaningful testosterone check, several blood markers are essential. The primary marker is **total testosterone**, which measures the overall circulating level. However, since most testosterone is bound to proteins, **free testosterone** (or calculated free androgen index) is crucial to assess the biologically active fraction. **SHBG** (sex hormone-binding globulin) influences binding and is therefore necessary. **LH** and **FSH** provide insight into the hypothalamic-pituitary-gonadal axis and help determine the cause of low testosterone (primary vs. secondary). **Prolactin** and **estradiol** may also be relevant, as elevated levels can disrupt testosterone production. Important: blood draw should be done in the morning (7–10 AM) due to circadian variation. A single measurement is limited; borderline results require repeat testing and medical evaluation. The 'Body-Balance Check' product may include these markers, but interpretation should always be done by a physician. Evidence: clinical practice, guidelines.
