What does the Oestriol (dried urine) test measure?

Oestriol (dried urine) (E3) is a clinical biomarker used in thyroid-endocrine assessment. Oestriol is a weaker oestrogen, formed by 16α-hydroxylation of oestrone and oestradiol. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is Oestriol (dried urine)?

Oestriol is a weaker oestrogen, formed by 16α-hydroxylation of oestrone and oestradiol. In non-pregnant adults it is a minor metabolite; in pregnancy the foetoplacental unit produces large amounts. Urinary E3 is often measured as part of functional oestrogen metabolism panels.

Why is Oestriol (dried urine) measured?

E3 is sometimes characterised as a less proliferative oestrogen with potential protective effects, though this remains debated. Its ratio to the other oestrogens is explored in functional risk assessments.
