- How to use the Free & Bioavailable Testosterone Calculator
The Free & Bioavailable Testosterone Calculator reduces the risk of errors that can occur when performing complicated calculations by hand. To use the app, input current lab values into the specified boxes for:
알부민
SHBG
Testosterone
Once lab values are in place, press the calculate button and let the Free & Bioavailable Calculator app do the math.
Free & Bioavailable Testosterone
테스토스테론 및 디 하이드로 테스토스테론 (DHT)은 혈장 결합 (약 2-3 % 자유), 특정 혈장 단백질 (SHBG)에 결합하고 알부민과 같은 비특이적 단백질에 약한 결합에서 순환합니다. The SHBG-bound fraction is biologically inactive because of the high binding affinity of SHBG for testosterone.
Bioavailable testosterone measurement includes the free plus the weakly bound.
Free testosterone measures the free fraction.
Certain health conditions and medications, such as corticosteroids, can affect SHBG levels, impacting total serum testosterone concentration. 알부민, 성 호르몬 결합 글로불린 (SHBG) 및 테스토스테론 수치를 결합하면 총 혈청 테스토스테론 농도의보다 정확한 측정을 제공합니다.

경고! The calculated free and bioavailable testosterone are reliable in most clinical situations, but should
not be relied upon in situations with potential massive interference by steroids binding to SHBG; eg in women
during pregnancy, in men during treatment inducing high levels of DHT (eg transdermal DHT, oral
testosterone) or mesterolon
