Use our Free Testosterone Calculator to determine your crucial free and bioavailable testosterone levels. Understand how SHBG and albumin impact these numbers, helping you assess your overall hormonal health and identify potential imbalances associated with symptoms of low T.
Formula:
Your Free Testosterone and Bioavailable Testosterone are calculated based on your Total Testosterone, SHBG (Sex Hormone-Binding Globulin), and Albumin levels.
This calculation utilizes established binding affinity constants (KSHBG, KAlbumin) to estimate the fractions of testosterone not bound or weakly bound to these proteins, providing a more accurate picture than total testosterone alone.
