On the eighth day of fresh embryo transfer, the blood HCG value is 34.99mIU/ml, whether it is normal or not mainly depends on the doubling of the blood value, if the blood value doubles in the recheck, it is normal, if the blood value does not double in the recheck, it is abnormal. Fresh embryo transfer pregnancy test is usually conducted 12-14 days after the transfer, and the blood value fluctuates from 50 to 500mIU/ml, and the results of the blood value may be inconsistent in different hospitals due to the difference of the manufacturers of the test kits. As some fresh embryos are slightly delayed after transfer, it will affect the amount of HCG secretion, which in turn will affect the results of HCG blood value of the blood test. Therefore, there is no definite range for the blood value on the 8th day of fresh embryo transfer. It mainly depends on the doubling of the blood value later, if the blood value doubles on the second check, it is normal, if the blood value does not double on the second check, it is abnormal. Checking the blood HCG too early may cause false-negative misinterpretation due to the lack of time, so you should avoid checking too early.
