The last stage of in vitro fertilization treatment is embryo transfer. After this stage, a pregnancy test is applied and the result of the treatment is learned. It is understood whether the in vitro fertilization treatment is successful or not during the pregnancy test phase, which is the most exciting period for the expectant mother and father during the in vitro fertilization treatment process.
It is necessary for the B-HCG hormone secreted by the embryo transferred into the uterus on the 3rd day to pass into the mother's blood. The period is 12 days and early tests do not give clear results. A pregnancy test is performed 12 days after the embryo is transferred into the uterus, and if the embryo is transferred on the 5th day, this period is 10 days.
Should a Urine or Blood Test be Applied to Detect Pregnancy?
Is it necessary for in vitro fertilization? Two methods can be used for pregnancy testing in pregnancies that occur through treatment or normal means. These methods are urine and blood tests. How Much Beta-HCG Hormone Should Be Secreted for Pregnancy?
In determining pregnancy, the Beta-HCG hormone in the blood is measured by testing. As a result of the blood test, if the Beta-HCG hormone in the blood is 0 or close to 0, it means that pregnancy has not occurred. In case of pregnancy, the Beta-HCG hormone in the blood must be over 50. Beta-HCG hormone may also be high in cases such as ectopic pregnancy or miscarriage. For this reason, even if the Beta-HCG value is high as a result of the blood test, it is necessary to follow up with ultrasound.
When Should Ultrasound Evaluation Be Done?
Ultrasound evaluation is performed approximately 10 to 14 days after the pregnancy test. . This period corresponds to 3 weeks after embryo transfer. In ultrasound evaluation, the occurrence of a single or multiple pregnancy, the gestational sac and whether the pregnancy is healthy or not are determined.
