Application of non-invasive preimplantation genetic screening for aneuploidy through spent embryo culture media analysis at 48 and 54 hours after embryo cleavage
Utilization of Non-Invasive Preimplantation Genetic Testing for Aneuploidy Detection
Overview
This study evaluates the effectiveness of non-invasive preimplantation genetic testing (niPGT) for detecting aneuploidy at 48 and 54 hours post-cleavage. The findings indicate that the concentration of cell-free DNA in spent culture media remains consistent, but the accuracy of ploidy detection compared to trophectoderm biopsy is reported as suboptimal.
Background
Aneuploidy significantly affects the success of in-vitro fertilization (IVF), particularly in women of advanced age, leading to increased risks of miscarriage and chromosomal disorders. Preimplantation genetic testing for aneuploidy (PGT-A) is a tool for identifying chromosomal irregularities in embryos.
Data Highlights
No significant distinction in ploidy detection accuracy was observed between SCM collected from embryos at 48 hours versus those at 54 hours post cleavage. The overall accuracy for sex determination reached 79.63%.
Key Findings
['The accuracy of niPGT in ploidy detection compared to trophectoderm biopsy was 53.71%.', 'Cell-free DNA content within spent culture media remained consistent across both time points.', 'No significant difference in ploidy detection accuracy was noted between 48 and 54 hours post cleavage.', 'The study involved a cohort of 15 infertile women and a total of 58 embryos.', 'Assisted hatching was performed during the cleavage stage on Day 3.']
Clinical Implications
Clinicians should consider the reported accuracy of niPGT when discussing genetic testing options with patients undergoing IVF.
Conclusion
The study reports that the accuracy of niPGT does not meet the standards set by traditional biopsy methods.
