PGT-A is a genetic test performed on embryos to identify numerical chromosomal abnormalities (aneuploidy).
Our technology, Next-Generation Sequencing (NSG), allows us to analyze all 24 chromosomes. Chromosomal abnormalities are detected prior to embryo transfer to enable ranking of embryos for transfer and increase pregnancy rates.
Independent studies have compared our PTG-A vs other labs and the key facts are as follows:
MitoScore is a mitochondrial biomarker developed by Igenomix which gives us an indicator of the energy status of an embryo.
MitoScore allows us to identify embryos with the greatest probabilities for implantation, and a viable pregnancy through IVF/ PGT-A.*
