An estrogen test is a blood test that measures the levels of estrogen hormones in the body. Estrogen is a group of hormones responsible for the development and regulation of the female reproductive system. Estrogen also has other important functions in the body, including regulating bone density, cholesterol levels, and the cardiovascular system.
There are different types of estrogen hormones, including estradiol, estrone, and estriol. An estrogen test may measure one or more of these hormones depending on the reason for the test.
Estrogen testing may be recommended for a variety of reasons, including:
To diagnose menopause: As women age, their estrogen levels naturally decrease, which can cause a range of symptoms such as hot flashes, vaginal dryness, and mood changes. An estrogen test can help determine whether a woman has entered menopause.
To evaluate fertility: Estrogen plays a key role in the menstrual cycle and ovulation. Measuring estrogen levels can help identify any hormonal imbalances that may be affecting fertility.
To monitor hormone replacement therapy: Estrogen replacement therapy (ERT) is a treatment used to manage symptoms of menopause. An estrogen test can help ensure that the dose of estrogen used in ERT is appropriate.
To prepare for an estrogen test, your doctor may recommend that you avoid certain medications, foods, or supplements that can affect estrogen levels. Your doctor will provide you with specific instructions on how to prepare for the test.
It's important to note that estrogen testing is just one part of a comprehensive evaluation of hormonal health. If you have any concerns about your estrogen levels or hormonal health, talk to your doctor.
This blood test measures the level of estrogen in a person's blood to evaluate fertility, diagnose menopause, or monitor hormone therapy. It may be recommended for women who have irregular periods, difficulty getting pregnant, or symptoms of menopause.
The report is usually available within a day or two.
Can be done from home using a home testing kit that involves collecting a blood sample using a fingerstick test kit.
Fasting is usually not required for this test.
