Key biomarkers - see full list below

  • You are experiencing irregular periods and you think that polycystic ovaries might be the cause
  • You are having difficulty getting pregnant and want to rule out or confirm polycystic ovary syndrome
  • You have symptoms such as acne, weight gain, or excess hair and want to investigate your male hormone levels
  • You want to check for diabetes and a thyroid disorder which you know are associated with PCOS
Polycystic Ovary Syndrome (PCOS) is a condition in women that results in the development of cysts on the ovaries which can become enlarged. PCOS is a common condition and in the UK affects around 7 in every 100 women. Investigations of PCOS focus initially on medical history, incidence of irregular periods (or none at all) and the existence of high levels of male hormones (androgens) in the body. Women who have PCOS may not ovulate (or may do so only infrequently) which can make getting pregnant difficult.

Our Polycystic Ovary Syndrome Blood Test checks your testosterone, sex hormone binding globulin (SHBG), luteinising hormone (LH), and follicle stimulating hormone (FSH). Indicators of PCOS include elevated testosterone levels, low SHBG and a LH/FSH ratio of over 2:1.

PCOS is also associated with thyroid disorders as well as metabolic conditions such as diabetes. This PCOS profile includes tests for thyroid stimulating hormone (TSH) and HbA1c, a marker for diabetes so that you can understand your risk for these conditions. 

If you are experiencing any PCOS symptoms or want to investigate your fertility status, this test is for you. Our doctors will interpret your results and let you know what action you should take next. 
You need to let us know the date of the first day of your last period (if you have them), this lets our doctors interpret your test accurately. You will receive an email asking you to complete this information in your MyMedichecks account, there is an option to tell us if you no longer have periods. This test is usually taken between days 2 and 5 of your period. Please take your sample in the morning. High dose biotin supplements can affect this test. If you are taking more than the recommended daily amount then you should not take your supplements for 2 days prior to this test. If you are taking high dose biotin for medical reasons (e.g. multiple sclerosis) then you should discuss this with your doctor. Use of oestrogen containing medications such as hormone replacement therapy or the combined oral contraceptive pill can affect the results of this test. Please use your MyMedichecks account to let us know if you are taking these. You will get more accurate results if you are able to take this test during a break from your oestrogen containing medication. If you are taking a finger-prick sample and you use any form of hormone-containing gel or pessary (eg hormone replacement therapy or testosterone replacement therapy) then we recommend that you take your blood sample from a finger which has not been in contact with the gel or pessary for several weeks, wearing a glove whilst applying the medication can help with this. The quality of your sleep can affect testosterone levels. Avoid taking your test when your sleep is likely to be disrupted, particularly if you are getting less than five hours sleep per night. Please use your MyMedichecks account to inform us of any medicines you are taking whether prescribed or over the counter.
