To have a healthy baby, preconception checkups are very important and both men and women need to do preconception checkups to ensure a normal pregnancy and a healthy baby. Pre-pregnancy check-ups for women are listed below: 1. Routine blood tests: You can find out whether there is anemia and platelets, etc., and help to detect thalassemia carriers, and the detection of blood type: if the wife is O blood type (RH negative) and the husband is A, B or AB blood type (RH positive), there is a possibility of fetal neonatal hemolysis. Liver and kidney function, blood sugar check. 2.Urinary routine examination: it helps in the early diagnosis of kidney disorders. 3.Gynecological white belt routine and ultrasound examination. Routine white belt examination can understand the presence of inflammation and timely treatment to avoid infertility or miscarriage; ultrasound examination helps to understand the situation of uterine attachments, such as the presence of uterine malformations, uterine fibroids, whether there are swellings in the ovaries, etc. 4.Electrocardiogram and chest X-ray examination. 5.Serological examination for syphilis and HIV test: these are the examinations for 2 kinds of sexually transmitted diseases. Syphilis can affect the fetus, but it can be treated, and as long as it is completely cured, you can get pregnant without worry. 6, measles antibody test: measles can cause fetal abnormalities when pregnant, so mothers-to-be who do not have antibodies are advised to receive measles vaccination first, but it should be noted that you cannot get pregnant within three months after vaccination. 7. Hepatitis B test: If you have hepatitis B or are a carrier of hepatitis B antigen, then your baby can be protected by immunoglobulin injections immediately after birth. If the test results show that you are neither a carrier nor have hepatitis B antibodies, it means that you are a susceptible person to hepatitis B, i.e., you are more likely to be infected with hepatitis B than others, so for insurance purposes, it is best to receive hepatitis B vaccination before pregnancy. 8. Pap smear: Stories of cervical cancer being discovered only when you are pregnant are heard from time to time, so a simple pap smear can give mothers-to-be more peace of mind when they are pregnant. 9. Virus and toxoplasmosis screening: Viruses that are toxic to the fetus include rubella virus, cytomegalovirus, coxsackie virus, herpes virus, EBV, and toxoplasmosis (not a virus). This test can be done in consultation with your doctor if you have had pets such as dogs or cats in your home or have had contact with animals, have eaten semi-cooked or raw meat, raw fish and raw vegetables in the recent past, have had recent contact with a rubella patient or have had an erythema or rash on your skin. These special pathogens may cause intrauterine infections in the fetus, but also one of the important causes of birth defects in newborns. 10. Other special tests such as endocrine tests, chromosome tests, etc. will be chosen by the doctor according to the specific situation.
