Our polycystic ovary syndrome blood test checks 15 key markers. Each one is an important part of the test, providing insight into what’s going on inside your body. Click on each marker listed below to find out more.
Testosterone levels can be affected by increased levels of Luteinising Hormone, causing an excess amount of testosterone. High levels of testosterone in women can cause a number of problems, such as unwanted hair growth and weight gain around the abdomen.
Luteinising Hormone (LH) is a key female hormones produced by the pituitary gland in the brain. The release of LH helps to stimulate ovulation. Checking luteinising hormone with follicle stimulating hormone (FSH) as part of a PCOS test is important for identifying the cause of any irregularity of periods.
Follicle Stimulating Hormone (FSH) is associated with the function of the ovaries. It’s important to measure FSH with LH when checking for PCOS, as high and low levels can indicate the cause of any irregularity of periods.
Oestradiol (oestrogen) is essential for the development of the female sex organs controlled by LH and FSH. Measuring oestradiol is important alongside LH and FSH to get a full picture of your hormone levels and how your ovaries are functioning.
We’ll check your blood sugar levels (HbA1c) as part of a PCOS test, as insulin resistance is a key association. High levels of insulin can increase the amount of androgens (male hormones) being produced, causing other symptoms such as unwanted hair growth and weight gain.
A prolactin test can be as part of a PCOS test to exclude any other causes of irregular periods.
Cortisol is helpful to exclude other causes or irregular periods and/or weight control issues
People with PCOS are at an increased risk of cardiovascular disease due to higher levels of cholesterol and/or triglycerides. We, therefore, measure your levels of HDL, LDL cholesterol and triglycerides as part of this test.
Polycystic ovary syndrome symptoms include irregular or no periods, difficulty conceiving, excessive hair growth or thinning of the hair, oily skin or acne, elevated levels of androgens (male hormones) and follicles on the ovaries.
We recommend you check for PCOS if you’re experiencing at least 2 of these symptoms, with a focus on irregular or no periods. Read more about the symptoms and take the PCOS quiz in our guide to PCOS.
Our PCOS (polycystic ovary syndrome) test checks your levels of testosterone which are raised in people with PCOS. It also checks the key hormones related to irregular periods to help rule out other possible causes. These include fertility hormones such as luteinising hormone (LH), prolactin, follicle-stimulating hormone (FSH) and oestradiol. We’ll also test your thyroid function and HbA1C levels.
You can complete the test at home in just a few minutes. We’ll analyse your blood sample to check the levels of each hormone and one of our medical professionals will review your results. You can access the results in our app at any time, giving you a full breakdown of each hormone.
According to the NHS, around 1 in 10 women in the UK have PCOS, with over half of them experiencing no symptoms.
You may notice changes in how your body looks if you’re living with PCOS. These changes can include weight gain, excessive and unwanted hair growth or hair loss, acne and oily skin. There are some things you can’t see, such as increased levels of androgens (male hormones) which you’ll only know if you take a blood test. Another sign of polycystic ovary syndrome is irregular or no periods. If you notice these symptoms, we advise taking a PCOS test or speaking to your GP.
You can lose weight when living with PCOS, but it can be more difficult due to increased insulin resistance. We have more information on weight loss on our guide to PCOS.
The exact cause of polycystic ovary syndrome is unknown, but there is some evidence linking it with genetics. PCOS is characterised with high levels of androgens (male hormones).
