How long is the earliest time for blood testing to yield results after 5-day implantation of 4bb blastocysts? I have uterine fibroids and my pregnancy preparation was unsuccessful. My first attempt to transplant fresh embryos into a test tube failed. I took a long time to recuperate before deciding on the second transplant. This transplant involves 4bb blastocysts that have been cultured for five days. Today is the second day after transplantation. I heard that blastocysts are usually implanted quickly, and I really want to know the implantation status of the embryo as soon as possible. Therefore, I would like to ask how long it takes to go to the hospital for a blood test.

The 4bb blastocyst matures in 5 days and can be implanted into the endometrium on the day of transplantation, with implantation taking about 2-3 days. If the female body is in good condition, the results can be measured around 7-10 days after transplantation, while if the female body is in poor condition, the implantation time of 4bb blastocysts will be relatively extended, and it may take around 12-14 days after transplantation to measure the results. So due to individual differences, the earliest time for blood sampling and testing after transplantation also varies, which needs to be determined based on the actual situation of the patient.

The blood test after blastocyst transplantation actually refers to the HCG blood test, which determines whether a woman is pregnant by detecting the HCG value in her blood. But the earliest time it takes for a pregnancy test after 5 days of 4bb blastocyst transplantation is still uncertain. After all, the physical condition of each patient is different, and the pregnancy test time is also different. The following is the time for sisters who have done test tube to share the blood test results after blastocyst transplantation:

On the fifth day after the transplant, I tested at home with a pregnancy test stick and found two. So on the sixth day after the transplant, I went to the hospital to draw blood for HCG testing, and the results showed that the HCG value was over 200. However, the doctor said that the HCG value at this time was meaningless, so I went to the hospital again 14 days after the transplant to draw blood for HCG testing.

I also transplanted blastocysts that lasted for 5 days and lasted for 4bb. I believe it was a failure to use a pregnancy test stick to test for pregnancy on the 9th day after transplantation. But 14 days later, I went to the hospital for a blood test and found that the HCG value was 75. The doctor said this is implantation, and the embryo may have just been implanted. Let me follow up and observe the doubling of blood HCG.

On the third day after blastocyst transplantation, a pregnancy test was performed using a pregnancy test rod and a blood test of 45 was conducted at the hospital. However, after going to the hospital for a blood test every two days, the blood HCG decreased by 10. On the 14th day after the transplant, the doctor said that the transplant failed. The previous increase in HCG was due to the influence of drugs, and after drug metabolism, HCG would decrease. Therefore, it is recommended not to undergo early pregnancy testing.
