Endometrial Receptivity Array or ERA is a test to check the endometrial receptivity. This is a genetic test that determines whether the endometrial lining is developed enough to receive the embryo. To analyze the endometrial receptivity, this new technology scans the expression of the 238 genes that are related to endometrial receptivity. This test assesses the optimal time to place an embryo that would help in a successful implantation and pregnancy.
