What it measures
- Prolactin — The main hormone measured; high levels can affect reproduction and milk production.
- Thyroid-stimulating hormone (TSH) — Sometimes checked because an underactive thyroid can raise prolactin.
- Estradiol — A form of estrogen that helps show if high prolactin is affecting ovarian function.
- Testosterone — Measured in men because high prolactin can lower testosterone.
