What Blood Tests Do I Need For PCOS?

If you think you might have PCOS, you should have a doctor perform a complete physical exam. A number of blood tests, including androgen and blood sugar levels, may also be ordered. In some cases, a sonogram of the ovaries may be ordered. Your doctor will perform these tests to rule out any other possible causes of the symptoms. The symptoms of PCOS are common, but can also be part of puberty.

Thyroid hormones

A complete PCOS health check-up test includes 65 test parameters, including lipid profile, thyroid function, uric acid, and prolactin. The test provides comprehensive information about many vital body functions, including ovulation, insulin sensitivity, and testosterone levels. The test also examines the levels of lipids, which are the primary building block of several hormones. These hormones are important to the body’s production of vitamin D, which plays an important role in fertility.

Anti-mullerian hormone

AMH blood tests can help diagnose polycystic ovarian syndrome, a common cause of infertility. It also helps physicians monitor the effects of ovarian cancer treatments. The anti-Mullerian hormone test is performed to evaluate the levels of AMH in a woman’s blood. However, it is not the only way to diagnose PCOS. Anti-Mullerian hormone levels can also help determine the effectiveness of ovarian cancer treatment.


The DHEA-Sulfate blood test is often ordered as a means to rule out a disease affecting the ovaries or testes. It can also be used to diagnose pituitary gland damage, since the adrenal glands control the production of DHEA-S. In adolescent girls, the test can be performed either before or after menstruation, since these events may alter the levels of hormones. For women who are planning to have a test, the doctor may ask them to wait until the end of their menstrual cycle, which will ensure that the blood is free from the effects of their periods.

Glucose levels

If you are concerned about your insulin level, you should ask your doctor about a blood test for PCOS. It can help your doctor determine whether you have the condition, which is also known as polycystic ovary syndrome. This hormonal disorder is associated with an increased risk of type 2 diabetes, which can be fatal. According to a study in Denmark, women with PCOS were diagnosed with type 2 diabetes four times earlier than the national average. The blood glucose level is determined by taking a fasting blood glucose test, which requires that you have a fasting period of 8 hours before the test, and then having a blood glucose test two hours later.

LH-to-FSH ratio

The normal FSH-to-LH ratio is one to one, but in women with PCOS, the ratio can be higher than one. This is because the amount of FSH in a woman’s body is greater than that of LH. If the ratio is higher than one, she may have PCOS, which is characterized by an abnormal egg development. To find out whether she has PCOS, your doctor will order a blood test called the LH-to-FSH ratio.


If you are wondering whether an hCG blood test for PCOS is necessary, read on to learn about the procedure and why it’s useful. PCOS is characterized by both hyperandrogenism and insulin resistance. Both factors are vital during the trophoblast invasion and placentation. Consequently, high levels of testosterone can indicate the possibility of PCOS. If you’re experiencing irregular periods, high levels of testosterone may also be the cause.


Thyroid function is a critical component of PCOS. A low TSH level may indicate an underlying condition such as thyroiditis. A high TSH level may indicate subclinical hypothyroidism. This condition may also be a precursor to diabetes. While this is a complicated process, blood tests for PCOS include TSH. This hormone levels in the blood of women suffering from PCOS.
