What is the ERA Test?
- The Endometrial Receptivity Analysis (ERA), developed and patented by Igenomix (PCT/ ES2009/000386), is a test designed to evaluate endometrial receptivity.
- The ERA test has been shown to be highly sensitive and specific in the detection of genetic expression profiles associated with receptivity. It allows a patient’s personalized window of implantation to be detected and applied to their future frozen embryo transfers.
What is the procedure?

- The ERA utilizes RNA obtained from an endometrial tissue sample. The RNA analyzed and then classified by our ERA predictor as receptive or non-receptive, depending on the expression profile of the RNA.
- If the endometrium is non-receptive, the test enables us to find a personalized window of implantation for each patient in the majority of cases.
