As reported in this article from BBC News Health, there may be a chemical “fingerprint” that can help doctors determine which embryos will implant more successfully for IVF patients by as much as 15%.
Scientists from Yale created the ViaTestE which scores the metabolic activity of some of the fluid surrounding the embryo with spectrophotometry. In a research trial testing this new way in comparison to traditional methods, it was found that the accuracy of ViaTestE is between a 60% and 70%, while currently there is only a 40% accuracy rate
This is especially helpful since doctors are trying to head in the direction of just implanting one embryo instead of multiple. Dr. Daniel Brison, co-director of North West Embryonic Stem Cell Centre had this important thought
"If we can get better at choosing the best embryo to implant then we can increase the efficiency of IVF, move towards single embryo transfers and thus reduce the risk to mothers and babies."
