What tests are available to diagnose PCOS?

Tests and diagnosis of polycystic ovary syndrom PCOS

There is no single test that can definitively diagnose PCOS. Diagnosis of PCOS is typically based on blood tests, medical history, and a variety of physical examinations to identify the presence of certain signs and symptoms. Many experts have determined that a woman must exhibit all of the following in order to be diagnosed with PCOS:

Irregular menstrual periods caused by irregular ovulation or a complete lack of ovulation (anovulation)

Signs pointing to higher than normal androgen levels. Visual signs can include excess hair growth, acne, or male pattern baldness. Blood tests can also be used to detect high androgen levels.

No other cause of excess androgen levels or irregular periods. Other causes may include congenital adrenal hyperplasia, androgen secreting tumors, or hyperprolactinemia.

Testing for PCOS

Typically blood tests are used to rule out other possible causes of menstrual irregularity and excess androgen levels exhibited by PCOS patients.

Pelvic ultrasound can also be used to examine the appearance of ovaries and the thickness of the lining of the uterus.
