What is Estriol (dried urine, GCMS)?

Estriol is a weak oestrogen produced in small amounts by non-pregnant women via 16α-hydroxylation of estrone and estradiol. It is the dominant oestrogen of pregnancy, synthesised by the foetoplacental unit, but contributes minimally to oestrogenic activity in non-gravid states.

Why is Estriol (dried urine, GCMS) measured?

Urinary estriol in non-pregnant women is included for completeness in oestrogen profiling and can be elevated in some liver or adrenal conditions. It is a minor component of the total oestrogen–metabolite picture.
