Could a simple calculation replace a complex testosterone lab test?
NCT ID NCT04807231
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compared two methods for measuring bioavailable testosterone in the blood: the standard lab test (radioimmunoassay) and a mathematical calculation. Researchers included 270 men and women aged 18 to 90. The goal was to see if the calculation matches the lab test closely enough to replace it, potentially simplifying future testing.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If the calculation method proves accurate, it could replace the more complex lab test, making testosterone measurement easier and cheaper.
What could go wrong
This is a completed observational study comparing two measurement methods. It does not test a treatment, so it won't directly change patient care.
