Estriol (E3) is a serum or urine-based diagnostic test that measures circulating levels of estriol, the weakest of the three primary estrogens, produced primarily by the placenta during pregnancy and by peripheral conversion in non-pregnant individuals. This test is used to support assessment of hormonal balance and may help practitioners monitor estriol status as part of a broader hormone evaluation panel.
Why It's Worth Considering: Offered through Access Medical Labs, this test is suited for practitioners seeking quantitative estriol data to inform clinical decision-making around hormone support protocols.
