A blank slate on the test result of an early pregnancy test strip indicates improper handling, or that the quality of the strip is faulty, or that it has become invalid. A blank slate test result is an invalid test result that does not indicate either pregnancy or the absence of pregnancy. A white plate test result 14 days after fertilized egg transplantation cannot be used as an indicator to confirm whether the transplantation is successful or not. If you want to determine whether the transplantation is successful, you need to visit the hospital for a blood HCG laboratory test. After 14 days of transplantation, if the transplantation is successful, the HCG level in the blood will be significantly elevated. If, after the test, the HCG level does not show an elevated trend, it is basically determined that the transplantation has failed.
