Estradiol blood test
What is Estradiol Blood Test?
Estradiol, also known as E2, is an estrogen hormone in women that helps regulate fertility and is important for healthy bones. In men, small amounts of estradiol help maintain optimal testosterone production. A estradiol blood test is used to measure the level of estradiol in the blood. High levels indicate that there are underlying medical issues that need to be addressed. Low levels can indicate an ovulatory disorder, a specific type of cancer, or a hormonal imbalance.
Preparation for the Estradiol Blood Test
No special preparation or fasting is necessary for the test. It can be done at any time during the day.
Procedure for the Estradiol Blood Test
The test involves a simple blood draw, and results are usually available within a few days. A technician will take a sample of your blood and send it to the lab where it will be analyzed for estradiol levels.
Types of Estradiol blood tests
There are three types of estradiol blood tests available. A single sample test measures the amount of estradiol in the blood at one point in time. A serial sample test measures levels over a period of time, and this test is used to track changes in estradiol levels. A quadruple sample test measures estradiol, as well as FSH, LH, and testosterone levels. This type of test is often used to diagnose polycystic ovarian syndrome.
Risks Associated with the Test
The test is safe and involves minimal risks. It is done via a simple blood draw, and any risks associated with the blood draw itself are minimal and can be addressed prior to the test.
Why it is Important?
Monitoring estradiol levels in the blood is important to ensure that the balance between the hormones is maintained in both men and women. It is especially important for women because it helps to identify fertility issues, as well as a number of diseases and disorders that may be present.
