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.

Why use ERA test?

This molecular diagnostic tool uses NGS to analyze the expression level of 248 genes related to the status of endometrial receptivity.
The ERA test resulted in a 73% pregnancy rate in patients with implantation failure.
ERA is backed by 33 publications; 29 from Igenomix and 4 external publications.
Proprietary algorithm based on machine learning that minimizes the need for second biopsy (90% of cases).
Allows clinicians to identify transition phases with 12 hours shifts.
Randomized clinical trial (NCT01954758) RCT proves cumulative live birth rate increases +16 points VS classic frozen blastocyst transfer in first appointment patients:

Who should use ERA test?

Women who have experienced implantation failure with morphologically good quality embryos.
Women with a morphologically normal uterus and normal endometrial thickness (≥ 6 mm), where the uterus and endometrium are unlikely to be the problem.

When to perform ERA to your Patient?

When is a second biopsy needed?

90 % of cases don’t need a second biopsy. The second biopsy is only required under two circumstances:

Patients with a “Pre-receptive 2 days” result.
Patients with a “Post-receptive” result.

The development of the ERA diagnostic tool was published in the paper by Díaz-Gimeno et al, 2011 (Fertil Steril. 2013 Feb; 99(2):508-17).

ERA´s effectiveness and consistency were demonstrated in the paper by Díaz-Gimeno et al, 2013 (Fertil Steril. 2013 Feb; 99 (2): 508-17).

ERA clinical applicability to patients with implantations failure was demonstrated in a publication by Ruiz-Alonso et al, 2013 and 2014.

What a difference two days make: “personalized” embryo transfer (pET) paradigm: a case report and pilot study Ruiz-Alonso M. et al, 2014. (Hum Reprod. 2014 Jun;29(6):1244-7)

A randomized study is currently in progress to assess its applicability to patients without any prior assisted reproduction treatment (ClinicalTrials.gov Identifier: NCT01954758).
