Pregnanetriol

Pregnanetriol, or 5β-pregnane-3α,17α,20α-triol, is a steroid and inactive metabolite of progesterone.

Urine testing

Urine excretion of pregnanetriol can be measured over a period of 24 hours. Elevated urine pregnanetriol levels suggest adrenogenital syndrome. In monitoring treatment with cortisol replacement, elevated urine pregnanetriol levels indicate insufficient dosage of cortisol.
