Estradiol E2

Estradiol E2 is used to evaluate ovarian function and determine the causes of infertility in women, including conditions such as hypogonadism and irregular menstrual cycles. IntroLab offers estradiol test as part of the diagnostic process.

What is Estradiol E2?

Estradiol E2 is the most important and active form of estrogen. In women, it is produced in the ovaries, while in men, smaller amounts are produced in the testes. This hormone has numerous roles in the body. This includes regulating the menstrual cycle, promoting breast growth and development, maintaining bone health, and regulating cholesterol levels. Estradiol E2 also plays a crucial role during pregnancy by stimulating the growth of the uterus and preparing the mammary glands for breastfeeding. Additionally, estradiol impacts mood, cognitive functions, skin health, and other aspects of overall health.

Medical Diagnostic Applications of Estradiol

Estradiol is used in medical diagnostics to assess hormone levels and evaluate the function of the reproductive system in women. Key applications include:

• Evaluation of the Menstrual Cycle: Estradiol levels are measured during different phases of the menstrual cycle to monitor normal hormonal fluctuations.
• Assessment of Ovarian Function: Measuring estradiol levels helps evaluate ovarian function and egg reserve, often used for women trying to conceive or before assisted reproductive procedures.
• Menopause Assessment: Estradiol levels can diagnose menopause or monitor hormone therapy in menopausal women. Low estradiol levels indicate decreased ovarian function and the transition to menopause.
• Monitoring Hormone Therapy: For women undergoing hormone therapy, measuring estradiol levels helps track the therapy’s effectiveness and ensure target hormone levels are achieved.

Test results aid doctors in diagnosing conditions, monitoring treatment progress, and evaluating reproductive function.

Estradiol Testing Procedure

Estradiol is often measured alongside FSH (follicle-stimulating hormone), LH (luteinizing hormone), progesterone, testosterone, and SHBG (sex hormone-binding globulin). For women, blood samples for estradiol measurement should be taken on specific days of the menstrual cycle or during particular stages of pregnancy, as advised by a doctor. No special preparation is required, but it is recommended to avoid taking the sample immediately after a meal.
