Application of non-invasive preimplantation genetic screening for aneuploidy through spent embryo culture media analysis at 48 and 54 hours after embryo cleavage
To assess the effectiveness of non-invasive preimplantation genetic testing (niPGT) for detecting aneuploidy at two different time points, 48- and 54-hours post cleavage stage of embryo development.
Key Findings:
Cell-free DNA content within SCM remained consistent across both time points.
The accuracy of niPGT in ploidy detection compared to trophectoderm biopsy was 53.71%.
No significant distinction in ploidy detection accuracy was observed between SCM collected at 48 hours versus 54 hours post cleavage.
Overall accuracy for sex determination reached 79.63%.
Interpretation:
Remove unsupported conclusions and rephrase to reflect findings only.
Limitations:
Small sample size of 15 women and 58 embryos.
Inconsistent outcomes and technical heterogeneity in previous studies.
Lack of definitive consensus on optimal timing for SCM collection.
Conclusion:
Remove unsupported conclusions and rephrase to reflect findings only.
Analysis of England’s multicancer early detection screening trial found modest, temporary diagnostic delays in participating regions, adding to concerns about health system effects and the evidence base for population-level blood-based cancer screening.
