Testosterone Free

What Does This Test Check?

This test measures free testosterone, the small fraction of the hormone not bound to blood proteins and therefore available to your body's tissues. It gives a read on active hormone rather than the larger total figure.

Lola Health offers the Testosterone Free test at £20, with results in one to four working days from a home sample. It is the only option on this page, so there is no provider comparison to weigh up.

A low free testosterone level may explain symptoms such as fatigue or low libido, but levels fluctuate through the day and a single reading does not confirm a deficiency. Discuss the result alongside your symptoms with your GP, who may suggest a total testosterone check too.
