How is polycystic ovary syndrome (PCOS) diagnosed?
Short answer
PCOS is diagnosed from a pattern of symptoms, medical history, and testing, not one test alone. A physician checks for irregular ovulation, signs of higher androgen levels, and sometimes ultrasound findings. They also rule out other causes. An ultrasound is not always needed to make the diagnosis.
A PCOS evaluation usually starts with your period history and symptoms. A physician may ask about acne, unwanted hair growth, scalp hair thinning, weight changes, and pregnancy plans. They will also review your medications and family health history.
In adults, diagnosis often requires two of three findings after other causes are ruled out: irregular ovulation, signs or blood tests showing higher androgen levels, or a certain pattern of follicles on an ultrasound. If irregular periods and higher androgen levels are already present, an ultrasound may not be needed. Diagnosis in teens uses different rules because puberty can cause similar changes.
Testing may include a pregnancy test and blood tests for hormones. Thyroid problems, high prolactin, and some adrenal conditions can resemble PCOS. A physician may also check blood pressure, cholesterol, and blood sugar to assess related health risks.
Online care can help start this review, but an exam, lab work, or imaging may still be needed. A licensed physician in your state decides whether telehealth care is appropriate or an in-person visit is needed.
