What is Testosterone, Free (Female)?
Free testosterone measures the biologically active, unbound fraction of testosterone circulating in the blood — the portion not bound to SHBG or albumin. In women, it reflects androgenic activity at the tissue level far more accurately than total testosterone, which is heavily influenced by SHBG fluctuations from estrogen, oral contraceptives, liver function, and thyroid status.
