The chromosome test is performed on an empty stomach to detect whether the couple is suffering from hereditary diseases, such as thalassemia. For women who have had habitual miscarriages or infertility, the chromosome test can help them understand the causes of infertility or habitual miscarriages. The results of the chromosome test for both spouses will be available in half a month, because the chromosome test requires cell culture, so it takes longer and the test report will clearly state the chromosome details of both spouses. If there are chromosomal abnormalities in both spouses, the fetus may be deformed, or the quality of the embryo may be affected after fertilization in the same room, and during the pregnancy, there may be pre-term miscarriage or the fetus may stop developing.
