EMMA can be performed on a small piece of an endometrial biopsy.
If the patient is undergoing an ERA test, a small portion of the same biopsy can be used, so no additional sample will be required
How to collect and send the sample
For EMMA, an endometrial biopsy should be taken from day 15 to day 25 of the menstrual cycle. After retrieval, it is important that the sample is briefly shaken vigorously and immediately placed in the refrigerator at 4–8°C for a minimum of 4 hours.
