Pregnant women who have regular maternity checkups will have their physical condition checked during early pregnancy. Such as blood, urine routine, blood coagulation, liver and kidney function, blood type, preoperative four, electrocardiogram, a variety of blood tests. If there is nothing wrong with the blood type and the preoperative quad (hepatitis B, hepatitis C, AIDS, syphilis), there is no need to be tested again during the whole pregnancy. Retesting is done when labor is imminent. Throughout the pregnancy, a pregnant woman’s health will change, and she will need to be retested for blood work to see if she is anemic. This is because more than 90% of pregnant women develop physiological anemia, and because of the increase in blood volume throughout the body after pregnancy, they are prone to dilutional iron-deficiency anemia. Correction is given in the middle and late stages of pregnancy. Before delivery, routine blood and urine tests, blood coagulation, liver and kidney function, and blood glucose are required. This is because pregnant women with diabetes mellitus, hypertension, or some damage to liver and kidney function are detected by liver and kidney function and blood glucose tests.
