How is pregnancy confirmed after an embryo transfer, and what tests are performed to verify the result?
After an embryo transfer, pregnancy is typically confirmed through a blood test that measures the level of human chorionic gonadotropin (hCG) in the blood. This test is known as a beta hCG blood test. The levels of hCG typically rise significantly if pregnancy has occurred. The test is usually performed about 10-14 days after the embryo transfer.
In addition to the beta hCG blood test, other tests that may be performed to verify the pregnancy result include:
1. Ultrasound: This imaging test can confirm the presence of a gestational sac, yolk sac, and fetal pole, usually around 6-7 weeks post embryo transfer.
2. Progesterone levels: Monitoring progesterone levels can also help confirm the viability of the pregnancy.
3. Repeat hCG tests: Sometimes, multiple blood tests may be done to monitor the trend and rate of rise of hCG levels, which can provide additional information about the progress of the pregnancy.
4. Transvaginal ultrasound: This type of ultrasound, which involves inserting a probe into the vagina, can provide more detailed images in the early stages of pregnancy.
It’s important to consult with your healthcare provider for the specific tests and timing they recommend for confirming pregnancy after an embryo transfer.
After an embryo transfer, pregnancy is confirmed via a blood test measuring hCG hormone levels, typically about 12 days post-transfer. An ultrasound will be done later to check for a gestational sac.
