Abstract: Disclosed in the present invention is a non-invasive detection method for screening for a well-developed blastocyst. A DNA methylation profile of a few of trophectoderm cells in a blastocyst is detected, and the average methylation level and the methylation pattern of embryos identified as having a good morphology in Gardner morphological blastocyst grading process are used as the standard for screening for well-developed blastocysts. The nearer the methylation level of the trophectoderm cells of the blastocyst to be tested approaches the methylation level or state of the good embryo, the better the embryo development is and the higher the suitability for being implanted into a maternal subject is. Furthermore, results of methylation sequencing may be analyzed to determine whether a chromosome is abnormal, so as to directly exclude chromosome-abnormal embryos.
