Recurrent miscarriage tests are performed to identify the possible causes of repeated pregnancy loss. They include a range of hormonal, immunological, and genetic analyses, along with blood tests to assess clotting and ultrasound examinations of the uterus and ovaries. These tests help detect issues that may affect pregnancy stability, such as hormonal imbalances, uterine abnormalities, or genetic factors, enabling the development of an appropriate treatment plan to improve the chances of a successful pregnancy in the future.
