What items need to be checked before pregnancy? What is unnecessary?

1, routine examination of hematology: this examination can know the level of hemoglobin, and anemia can be treated first; You can also get the value of platelets, which are related to coagulation function. Too much or too little will lead to bleeding, so people with platelet problems should be treated first before they are suitable for pregnancy. This test can also measure the size of red blood cells (MCV), which is helpful to find thalassemia carriers. The red blood cells of thalassemia carriers will be smaller and the MCV will be lower than 80. This disease is a recessive genetic disease, and only when both parents are carriers will it affect the next generation. Therefore, if the expectant mother's MCV is lower than 80, the prospective father must also draw blood. If both sides are below 80, further tests are needed, such as blood electrophoresis and DNA testing. If only one side's MCV is less than 80, don't worry. This is a genetic disease that can be diagnosed before delivery, so there are very few newborns suffering from thalassemia in recent years. Therefore, CBC can be said to be a low-cost and important test. 2. Syphilis serum test and HIV test: These are two tests of sexually transmitted diseases. Syphilis can affect the fetus, but fortunately, syphilis can be treated, as long as it is completely cured, it can be safely pregnant; AIDS is trouble, but at least we can't let the adult Black Death affect the next generation, and we can't let innocent AIDS babies come into this world. 3. Measles antibody detection: Measles during pregnancy will cause fetal abnormalities, so it is best for expectant mothers without antibodies to receive measles vaccination first, but it should be noted that they can't get pregnant within three months after vaccination, and contraceptive measures should be taken. 4. Hepatitis B examination: Hepatitis B itself will not affect the fetus. Even if the mother is a highly contagious or hepatitis B antigen carrier, the newborn can be protected by immunoglobulin immediately after birth. However, it is always reassuring to know whether you are a carrier of hepatitis B antigen before pregnancy. If you are neither a carrier nor an antibody, you can receive hepatitis B vaccination first. Prevention is better than cure. 5, cervical curettage: I heard the story of cervical cancer when I was pregnant, so simple cervical curettage can make expectant mothers feel more at ease when they are pregnant. After all, a good uterus can give birth to a healthy fetus. If the expectant mother's disease is not diagnosed and treated before pregnancy, it will not only be harmful to the health of the fetus, but also endanger the mother. The pre-pregnancy examination mentioned above is very simple. As long as it takes half a day, almost all hospitals can do it, suitable for every expectant mother. There are also some special examinations, mainly aimed at various genetic diseases, which require separate consultation.
