How PCOS is diagnosed

PCOS is diagnosed when you have at least two of three features: irregular or absent ovulation, signs of high androgens (on a blood test, or symptoms such as excess hair and acne), and polycystic ovaries on an ultrasound scan. Other causes of similar symptoms need to be ruled out first. This profile covers the blood test side in one go.

Why prolactin, cortisol and DHEA-S are included

High prolactin can cause irregular periods. A raised DHEA-S points to androgens coming from the adrenal glands rather than the ovaries. Cortisol helps screen for rarer conditions that can mimic PCOS. AMH is often raised in PCOS, adding a useful extra clue.

How to prepare

  • If you have periods, book for day 2 to 5 of your cycle (day 1 is the first day of full bleeding). If your periods are irregular or have stopped, any day is fine.
  • Morning appointments are best, as cortisol and testosterone are highest early in the day.
  • Stop biotin (vitamin B7) supplements, often found in hair, skin and nail products, 48 hours before.

Questions

Do I need a scan as well?

Not always. If you have irregular periods and raised androgens, PCOS can be diagnosed without a scan. Your GP will advise.

Can I test while on the pill?

The pill lowers androgens and can mask PCOS, so results are most accurate off hormonal contraception. Talk to us or your GP before stopping any medication.
