The 21 day test for fertility is a blood test that measures your progesterone levels. This hormone helps your body prepare for a fertilized egg to implant.
In addition, this test also checks your FSH level and estradiol. These are important hormones that track a woman’s ovaries and help determine her fertility and response to treatment.
What is the 21 day test?
If you’re trying to get pregnant, your doctor may recommend a fertility test called the 21 day test. This is done about seven days before your next menstrual period to check progesterone levels and confirm that you have ovulated successfully.
Aside from ovulation, progesterone is one of the main hormones in your body that prepares for a pregnancy. It rises in your bloodstream following ovulation and peaks at about 7 days before your period.
Fertility hormones E2, FSH, and LH all fluctuate over time based on where you are in your cycle. Testing these hormones on any random day can give you results that aren’t accurate.
Because of this, it’s important to test your fertility hormones on day 3 of your menstrual cycle (day 1 is the first day of your full flow). By testing these hormones on the right day, we can get more clinically meaningful results. That’s why the doctors at UT Southwestern’s fertility assessment center recommend this test for our patients.
Why is it done on day 21?
The 21 day test for fertility is a blood test that checks levels of progesterone and estradiol (E2). It also measures the thickness of your endometrium, which is the lining of your uterus.
It is often done on the 21st day of a menstrual cycle, depending on your usual cycle length. This is a great step in your treatment plan because it helps your doctor understand what hormones are normal and what may be inhibiting fertility.
However, it can be misleading if you do not have a “textbook” cycle. In this case, your cycle length may be longer or shorter than average.
This means that your blood draw on Day 21 would not be accurate, and it could result in a lower progesterone level than your actual ovulation level! So, before your fertility specialist suggests a 21 day test for you, they will need to confirm your typical cycle length and your ovulation day. This is what will give you a more reliable result!
What is the 21 day test used for?
The 21 day test is a blood test that checks the levels of progesterone and estradiol (E2) in your system. These hormones are important for fertility and help your body prepare for pregnancy.
Progesterone is a natural hormone that’s produced in your ovaries, which are two glands in your female reproductive system that contain eggs. It’s important for ovulation, the process where an egg is released and becomes fertilized by a sperm.
It also helps the uterine lining grow thicker so that a fertilized egg can attach inside the uterus.
Your doctor may recommend the 21 day test if you haven’t ovulated in several months, or if you have other issues with your fertility.
This blood test is typically performed by fertility specialists who work with women who want to get pregnant. It’s often used as a part of initial or ongoing fertility workups to provide a more comprehensive picture of possible causes of infertility and vaginal bleeding.
How is the 21 day test done?
The 21 day test is a blood test that’s done around the same time as your next menstrual cycle (depending on how long your cycles usually are). It checks the levels of progesterone and estradiol in your system, and measures the thickness of your endometrium.
