How Is PCOS Diagnosed? Tests, Criteria & What to Expect
The official PCOS criteria
Doctors use the Rotterdam criteria. You need two out of three:
Irregular or missing periods (irregular ovulation)
High androgens (via symptoms or blood tests)
Polycystic ovaries on ultrasound
Tests your doctor may run
Blood tests: testosterone, LH, FSH, SHBG, prolactin, thyroid, insulin
Ultrasound: checking ovary structure
History & symptoms: cycles, acne, hair growth, weight, fertility struggles
Why diagnosis matters
Validation → you’re not imagining things
Tailored support → nutrition & lifestyle plans can target your drivers
Future health → early management reduces risks like diabetes
