Serum Free Testosterone Titration

Meaning

Serum Free Testosterone Titration is the clinical practice of precisely adjusting the dosage of exogenous testosterone or testosterone-modulating agents to achieve a specific, desirable concentration of unbound, biologically active testosterone in the blood serum. This unbound fraction is what actually interacts with androgen receptors throughout the body. Titration is a continuous process guided by symptom resolution and biomarker response. We must account for binding proteins.
