Free Testosterone levels: what's normal, high and low
The biologically active, unbound fraction of testosterone. Often more clinically meaningful than total.
Medically reviewed by Youmna DiStefano, MD · Last reviewed September 2026
The short answer
Free Testosterone is measured with a standard blood draw; no fasting is needed. A typical reference range is 47.0 – 244 pg/mL (male, age 18+; more bands below). At TestWell it's $54.99 all-in as Testosterone, Free & Total, results in 3–5 business days, drawn at Quest or Labcorp. An out-of-range result is a prompt to look closer, not a diagnosis.
