To Test or Not to Test

After the embryo transfer,  it is normal to feel mixed emotions of being excited and nervous. You and your Intended Parents have been anxiously preparing for this moment in your journey for months. Often the most emotional and hardest time in the process is the wait between transfer and the beta hCG pregnancy test. The two-week wait to learn if the transfer was successful can be full of stress and anxiety for the Gestational Carrier and Intended Parents. It often feels as if time has stopped. It is best to find ways to keep yourself busy to distract yourself. You can continue with your personal life while being mindful of any restrictions put in place by the clinic.


You may be eager to take at home pregnancy tests before your beta hCG blood test. Although it is tempting to take an at home test, it is important to have a conversation with your Intended Parents prior to testing at home to discuss if they are comfortable with it. If they are, do they want to be informed of the results? Or would they prefer to not know until the medical confirmation. It is also important to remember home pregnancy tests do not always confirm a successful embryo transfer. Even if you receive a positive test result, it could be a false positive or medical issues could come to light and it may not be a viable pregnancy.  They can often lead to false hope for everyone and increased anxiety and stress. It is encouraged to wait for the beta hCG blood tests, as they are the most accurate way to confirm a successful transfer. 

Beta hCG

HCG (Human Chorionic Gonadotropin) is often called the pregnancy hormone. Once an embryo has implanted in the uterus the hormone is produced and can be detected in the blood. Quantitative hCG testing, often called beta hCG (β-hCG), measures the amount of hCG present in the blood. Approximately 9-11 days after the embryo transfer, you will have blood drawn to test for hCG levels. If the test is positive, you will continue your medication and repeat the test in two days to check for an increase in hCG level. Home pregnancy testing is unable to determine whether or not the levels are increasing, which is the true way to determine if it is a viable pregnancy. If the level increases appropriately you will be scheduled for an ultrasound in approximately two weeks. 

As mentioned, the most accurate way to determine a successful transfer is to wait for the beta hCG blood test. For informational purposes, we have included an informational video that breaks down the home pregnancy test process and how it works. 

How Pregnancy Tests Work

 We have also included the most common over the counter pregnancy tests and their sensitivity to hCG in your urine. If you are going to choose to take an at home test, it is best to choose one that has a lower sensitivity level.
