Estradiol

What this laboratory test evaluates

Estradiol Test
This test measures the levels of estradiol in the blood, which is crucial for checking ovarian function and tracking follicular development in fertility treatments. Estradiol is key throughout the menstrual cycle. High levels in women can indicate ovarian hyperfunction or be seen in pregnancy and fertility treatments. Low levels might suggest ovarian issues or problems with the hypothalamus-pituitary axis. In men, high estradiol levels can lead to gynecomastia due to increased conversion of androgens.

What patients is this test right for?This test is suitable for individuals monitoring ovarian function, undergoing fertility treatments, or experiencing symptoms related to abnormal estradiol levels.

High Estradiol Symptoms:• In females: Signs of ovarian hyperfunction
• In pregnancy
• In males: Gynecomastia
Low Estradiol Symptoms:• Lack of ovarian synthesis
• Menopause
• Issues with the hypothalamus-pituitary axis

What type of sample is required for this test?1 mL serum.
