There's no single PCOS test
PCOS is diagnosed when at least two of three features are present: irregular or absent ovulation (often showing up as irregular periods), signs of high androgens (either on examination, like excess hair or acne, or on blood tests), and polycystic-appearing ovaries on ultrasound. Other conditions that can mimic PCOS need to be ruled out first.
This is why there's no single 'PCOS test' — it's a picture built from several pieces.
What your GP will do
Your GP will start with a detailed history of your cycle, skin, hair, weight and any fertility concerns. They'll usually arrange blood tests to check hormone levels (including androgens), and to exclude other causes such as thyroid problems or high prolactin.
They may also check markers linked to insulin resistance and metabolic health, since these are common in PCOS and important to manage.
Ultrasound and next steps
A pelvic ultrasound may be arranged to look at the ovaries, though it isn't always required to make the diagnosis — particularly in younger women, where polycystic-looking ovaries can be a normal finding.
Much of this assessment can be started via telehealth: your GP can take the history and arrange the blood tests and ultrasound, then review the results with you. If you suspect PCOS, book a consult to get the process underway.
