What is the Eeva Test?

Eeva stands for Early Embryo Viability Assessment; the EevaTM Test is a non-invasive test used with IVF, and looks at an embryo in its early stages of development in an incubator.

Using time lapse technology, images of the embryos development are captured from Day 1 to Day 3 of development.

The time-lapse images are analyzed by proprietary computer software that assesses the patterns and timing of cell division, identifies the further developmental potential of the embryos, and categorizes them into “High” and “Low.”

“It tells us which embryos are more likely to become blastocysts or Day 5 embryos and which embryos are not as likely to develop into blastocysts. Research suggests that embryos that reach the blastocyst stage have a higher implantation potential,” says Dr. Eve Feinberg, with Fertility Centers of Illinois. “We can also use the technology to help select the best blastocyst for transfer in a situation where we have multiple high-quality embryos. Going back in time and looking at those time-lapse images and the Eeva Test result really helps us to pick the best embryo to transfer.”
