The invention discloses a method for non-invasive preimplantation hereditary detection of embryos, and belongs to the technical field of biological detection. The method comprises the following steps:carrying out whole genome amplification on a blastocyst culture solution sample by using a kit, carrying out short tandem repeat sequence analysis on an amplification product and DNA samples of parents to detect maternal pollution, carrying out library preparation and next-generation sequencing detection on the amplification product to determine whether the number of chromosomes is abnormal or not; and optimizing a pre-amplification mixed solution and an amplification mixed solution by the provided kit. According to the method provided by the invention, the blastocyst culture solution can besubjected to parent source pollution detection, so that whether the chromosome aneuploidy detection result of the culture solution is accurate and reliable or not is judged. The invention provides a detection method for judging whether granular cells are completely removed or not, and the inhibition effect of components in the culture solution on amplification is effectively avoided through optimization of the kit, so that amplification uniformity is good, and the single cell amplification yield is high. The detection method is simple, the result is accurate, and data quality is improved.
