Test ERA (Endometrial Receptivity Array) is a molecular diagnostic test to investigate the receptivity of endometrium. Receptivity of the endometrium is a condition in which the endometrium (uterine lining) is ready for implantation (nesting) of the embryo.
The ERA test, ie the “Endometrial Receptivity Assay” test, is a method used in cases of embryo implantation problems, when pregnancy cannot be achieved despite several transfers of healthy embryos.
With the Era test, it is now possible to predict whether the uterus is receptive to the embryo before the transfer, or if the embryo transfer was performed on the appropriate day. This way, the success rate of the pregnancy can be increased.
The ERA test can increase the possibilities of a successful pregnancy in patients pursuing frozen embryo transfer because we can time the embryo transfer to be within the window of time when implantation is most likely to occur.
