Correct time of IVF pregnancy test
IVF is a kind of assisted reproductive technology, which is usually used to solve the problem of fertility disorders. The success rate of IVF is closely related to the time of pregnancy test. This article will elaborate on the correct time of IVF pregnancy test from four aspects: gynecologist's suggestions, waiting time after IVF transplantation, progesterone test and urine hCG test.
Suggestions of gynecologist
After choosing IVF treatment, gynecologists usually give corresponding suggestions according to individual conditions. A pregnancy test is generally recommended 14 days after embryo transfer. This is because after embryo transfer, if the fertilized egg is successfully implanted, the body will begin to produce the pregnancy hormone human chorionic gonadotropin (hCG), and gradually rise to a level that can be detected by urine.
However, some women may try themselves ahead of time. This is because some women are sensitive to pregnancy, and may feel capsule rupture, breast distension, pain in the lower abdomen and other symptoms 8-10 days after transplantation. However, these symptoms do not necessarily mean a successful pregnancy, which needs to be confirmed by pregnancy test.
Therefore, it is recommended that women respect the recommendations of gynecologists and follow the 14 day time for pregnancy test to ensure the reliability of the results.
Waiting time after IVF transplantation
It will take some time to observe the results after embryo transfer. Generally speaking, the waiting time after IVF transplantation is 10-14 days. During this period, women should keep their mood relaxed and avoid overwork and mental tension.
The length of waiting time depends on individual differences and the stage of embryo transfer. Some hospitals may choose to transfer embryos after the embryo culture reaches the blastocyst stage. At this time, the waiting time will be slightly longer. For the first attempt, some women may be overly anxious, but the results of early pregnancy tests are often inaccurate, and it is easy to produce false negative or false positive results.
Therefore, it is very important to be patient in the waiting time after IVF transplantation and not carry out pregnancy test in advance.
Progesterone test
Progesterone is a hormone secreted by corpus luteum in early pregnancy, which is very important for maintaining pregnancy. In IVF treatment, gynecologists usually arrange progesterone test to help judge whether the pregnancy is successful.
The progesterone test is generally conducted 7-9 days after IVF transplantation. By detecting the change of progesterone level, doctors can preliminarily judge whether there is implantation and pregnancy. If the progesterone level is low, supplementary treatment may be required to improve the probability of successful implantation and pregnancy.
However, progesterone test can not 100% determine whether the pregnancy is successful, and it needs to be confirmed by pregnancy test finally.
Detection of hCG in urine
HCG (Human Chorionic Gonadotropin) is a hormone that only exists in pregnancy, and is one of the most commonly used indicators to judge whether or not pregnancy. Because hCG gradually rises after implantation of fertilized eggs, it can be detected in urine.
It is generally recommended that urine hCG testing be performed 14 days after IVF transplantation. This period has been long enough for the blastocyst to secrete hCG stably after embryo transfer. Through urine detection, more accurate results can be obtained to judge whether the pregnancy is successful.
It should be noted that if urine hCG detection is carried out in advance, it may lead to inaccurate results, because the hCG level may not reach the level that can be detected by urine at this time.
Summary
The time of IVF pregnancy test is very important, which has an important impact on the accuracy and reliability of the results. The advice of the gynecologist is the primary basis, and it is generally recommended that a pregnancy test be conducted 14 days after embryo transfer. The waiting time after IVF transplantation is 10-14 days, the progesterone test is usually performed in 7-9 days, and the urine hCG test is performed in 14 days. Following the correct time for pregnancy test can obtain more accurate results and reduce the possibility of wrong judgment.
Therefore, it is very important to know the correct time of IVF pregnancy test and operate according to the doctor's recommendations.
