Using Illumina technology, preimplantation genetic screening (PGS) methods can screen all 24 chromosomes in as little as 12 hours for an accurate, efficient view of the number of chromosomes in an embryo.

In the past, embryo selection was based solely on morphology, a subjective method evaluating appearance of an embryo using a scoring system. FISH analysis can also be used as way to assess chromosome number; however it’s only able to identify a limited number of chromosomes.

Hear Simon Fishel talk about screening all 24 chromosomes with PGS.

A Brief History of PGS


Preimplantation genetic screening was originally performed using fluorescence in situ hybridization (FISH). Because FISH does not screen all 24 chromosomes, its efficacy and accuracy for detecting euploid embryos is limited.


As new technologies were developed and applied to PGS, IVF outcomes improved. The array-based 24sure technology facilitated screening of all 24 chromosomes in the embryo, significantly improving PGS.

Next-Generation Sequencing

NGS, the latest technological breakthrough, is setting a new standard in PGS. NGS offers reliable PGS results, streamlined workflows, higher throughput capabilities, and customizable assays for easy portfolio expansion.

24sure Microarrays

Preimplantation genetic screening with 24sure microarrays provides a comprehensive and accurate assessment for aneuploidy in all 24 chromosomes from an embryo biopsy. The arrays can be used to screen for aneuploidy in first and second polar bodies, blastomere biopsies, and trophectodermal biopsies.
