This retrospective study gathered data from embryos of donor oocytes that underwent trophectoderm biopsy and PGT-A from four different laboratories to investigate variation in euploid blastocyst rate and live birth rate across different laboratories when controlling for blastocyst quality. Results from the study suggest that there are differences in euploid blastocyst rate and live birth rates for a young and healthy population between laboratories, suggesting that not all PGT-A laboratories are comparable.
