The Eugenics IV test is to check for various viral infections in a woman’s body, mainly consisting of Toxoplasma gondii, rubella virus, cytomegalovirus and herpes virus. The cost of the Eugenics IV test is usually between$70-80, which varies from hospital to hospital. It is recommended to take venous blood on an empty stomach to check for viral infections, because viral infections may affect pregnancy and may lead to embryonic abortion or spontaneous miscarriage after pregnancy, so it is recommended that women preparing for pregnancy should have routine eugenics tests before conception.
