The ERA test involves performing an endometrial biopsy and analyzing the expression of 248 genes related to endometrial receptivity in that sample. In this way, it is possible to identify whether or not the endometrium is receptive at the exact time when the biopsy was done, with the aim of finding out the exact days of the implantation window and being able to make an embryo transfer with guarantees of success.
The results of the ERA test will tell whether the endometrium is receptive, pre-receptive, post-receptive or, on the contrary, the window of implantation is displaced.
