Era test

The ERA test (Endometrial Receptivity Analysis) is a diagnostic test designed to examine the receptivity of the uterine lining (so-called endometrium). 

It is a very precise tool for the examination of the uterine lining, especially for women with repeated failure of embryo implantation. It is performed by analyzing a sample of endometrium obtained by biopsy, which is then evaluated by genetic analysis for its receptivity, i.e. the time when the endometrium is ready for implantation (nesting) of the embryo. 

Normally, the mucosa is examined by ultrasound, but this can only reveal its height and structure. In contrast, the ERA test offers new ways to examine the endometrium and increase the chances of a successful pregnancy.

The ERA test can identify, at the molecular level, whether the mucosa is in the so-called receptive period, i.e. the period suitable for embryo implantation, or whether the so-called "implantation window" has been postponed. It has been shown that 3 out of 10 women have a shifted implantation window of the uterine mucosa.

The ERA test is considered to be an extension of the classical examinations of infertile couples, therefore it is not covered by the health insurance system. It is paid for by the patient herself.
