Oestriol is a form of oestrogen produced by the placenta.
About three to five weeks before labour begins the amount of estriol in the placenta increases dramatically.
Although oestriol is most commonly linked to pregnancy since it is produced in the most measurable amounts at that time, it is still present throughout a woman’s lifetime at varying levels.
We will send you your Oestriol blood and test sample collection kit together with the details of a convenient clinic where you can go and have your sample taken.
Your Oestriol test includes 1st class postage and packaging for you to send your blood and sample directly to our laboratory for analysis. If you live in an area where you cannot rely on the post or you simply want to ensure that your sample arrives at the laboratory the following day, you may wish to send your blood and sample guaranteed next day delivery for extra reassurance.
