Blood Test for Low Libido
May 8, 2026
Blood Test for Low Libido
A blood test for low libido investigates the hormonal and medical causes of reduced sex drive—including testosterone deficiency (in both men AND women), thyroid dysfunction, elevated prolactin, oestrogen imbalances, and other treatable conditions—because libido problems often have a physiological explanation that can be addressed.
At Blood Test London, our libido investigation panel costs from £295 with results in 2-3 days. A doctor always reviews every result.
