I. Blood test (blood type): Early detection of anemia and other blood system diseases, because if the mother is anemic, not only will there be complications such as postpartum bleeding and puerperal infections, but also the baby will be affected, bringing a series of effects to the baby, such as susceptibility to infection, decreased resistance, and backward growth and development. Second, all types of hepatitis, liver damage diagnosis: if the mother is a viral hepatitis patient, not detected in time, pregnancy can cause very serious consequences, premature birth, and even neonatal death. Hepatitis virus can also be transmitted vertically to the child. China is a high prevalence of hepatitis B. There are 350 million hepatitis B virus carriers (hbsagv+) in the world, and China has as many as 120 million, accounting for 1/3 of the world, and about 25% of those who carry the virus will develop chronic liver disease during their lifetime. The transmission of hepatitis B mainly includes mother-to-child transmission, life contact sexual transmission, hbsagv +) babies born to mothers, within 1 year of birth will be 25% to 40% become hbsag (+), in newlyweds, one party hbsag (+), the other party is not infected, 2 to 25 years after marriage, the original uninfected party 52.6% of the occurrence of hepatitis B virus infection, of which 14% became hepatitis B virus carriers. If the male partner is found to be hbsag(+), giving the female partner a full immunization with hepatitis B vaccine can effectively prevent the infection of the female partner and vertical transmission from mother to child; if the female partner is hbsag(+), through premarital health guidance, informing her to carry out hepatitis B “triple blocking” after pregnancy can effectively prevent mother-to-child transmission, thus reducing the mother-to-child The rate of mother-to-child hepatitis B virus infection can be reduced by 2/3. Three, “four viruses” test: rubella virus, cytomegalovirus, toxoplasmosis virus, herpes simplex virus. Although most infections in pregnant women do not have typical symptoms, serious sequelae can often occur in the fetus after infection. Check these several pathogens before pregnancy to confirm your immune status. Fourth, check the AIDS virus (aids): HIV transmission is mainly sexually transmitted, pregnant women infected with aids virus can infect the fetus through the placenta or birth through the birth canal after breast milk infection of the newborn. Fifth, syphilis serological examination: it is worth noting that in the past six years, the number of STDs in the marriage population has increased at an annual rate of 66.72%, the vast majority of which is syphilis, and 85% of the insidious syphilis, the patient is completely unknown, and syphilis is second only to AIDS on the body’s most damaging STDs. It is subtle, “eating” the body, health hazards, it can be transmitted to the spouse, resulting in offspring miscarriage, premature birth, stillbirth, congenital syphilis in newborns, etc.. However, this disease as long as early detection, early treatment, is completely curable. VI. Routine urine examination: it helps in the early diagnosis of kidney disorders. Ten months of pregnancy is a great test for the mother’s kidney system, and the increased metabolism of the body will increase the burden on the kidneys. If kidney disorders exist, the consequences will be very serious. Seven, chromosome testing: early detection of genetic diseases such as Crohn’s disease, Turner’s syndrome, infertility. Eight, check abo hemolysis: the couple to check the blood type to avoid infant hemolysis, miscarriage, stillbirth, deformities and other pathologies. Nine, chest fluoroscopy, radiographs: first of all, the diagnosis of tuberculosis and other lung diseases, women suffering from tuberculosis pregnancy will make the treatment of medication is limited, so that treatment is affected. Moreover, active tuberculosis is often aggravated by postpartum exertion, and there is a risk of transmission to the child. Ten, neural tube malformation screening: China is a country with a high incidence of neural tube malformation, the incidence is 10 times that of the United States. If taken orally from the first trimester to the second trimester, Silien tablets (a small dose of folic acid tablets) can reduce the incidence of neural tube abnormalities by more than 70%. By taking blood for “Down’s syndrome screening” at 14-20 weeks of pregnancy, it can reduce the birth of congenital dysmorphic children by 60% to 70%. Eleven, echocardiography: check the function of the heart, if not normal will cause blood flow disorders, causing abnormalities in the placental vessels, resulting in miscarriage, premature birth and maternal body and life will be threatened. Twelve, breast examination: to understand whether there is breast hyperplasia, breast fibroids and other breast disorders. Do early treatment to prepare for the breastfeeding period.
