Polycystic Ovary Syndrome (PCOS) is a condition in which your ovaries are enlarged and contain many fluid-filled sacs around the eggs. It is quite common and affects normal ovarian function. A diagnosis is based on medical history, symptoms and high levels of male hormones (androgens). Our Advanced Polycystic Ovary Syndrome (PCOS) Blood Test contains a comprehensive hormone panel, including tests for the hormone’s testosterone, FSH, and LH. It also measures anti-Mullerian hormone (which can be raised if you have PCOS) and prolactin (which can give insights into your fertility). Our advanced profile also includes tests for thyroid function, diabetes and cholesterol, all of which can be affected by polycystic ovaries. Avoid fatty foods for eight hours before your test, you do not need to fast. Take this test two to five days after the start of your period, ideally on day three. It can be taken any time if you do not have periods. Hormonal contraception can affect this test, taking a break from this and using barrier contraception will give more accurate results. If you use hormone gels, pessaries, patches, or tablets, we strongly recommend selecting our intravenous blood test to minimise contamination. Do not take biotin supplements for two days before this test, discuss this with your doctor if it is prescribed.
