Premarital and preconception tests are often confused, and some people even think that they don’t need to do preconception tests after having premarital tests, but there is a difference between the two. Although both premarital and preconception tests include tests for both genetic diseases and reproductive health, preconception tests will have additional targeted programs for pregnancy. Preconception tests are generally offered due to hospitals, which means that they represent individual local preconception tests and generally there is no uniform standard. The preconception test has additional tests for toxoplasmosis and herpes virus than the premarital test so that you can be sure of your health and be prepared for the next preparation for pregnancy. After having a premarital test, you may start preparing for pregnancy years after you are married. So the premarital checkup at the beginning is only to check the health of both partners, and when you are really ready to start preparing for pregnancy, there may be different changes in your body, so you have to do the preconception checkup again to see if you have the possibility of having children. The above questions are for reference only. Please refer to the doctor’s guidance for specific medication and treatment in an interview.
