Pregnant women during pregnancy are extremely fragile. For the health of themselves and their unborn babies, expectant mothers need to go to the hospital for various examinations. Even if they rush to the hospital again and again, expectant mothers have no regrets, after all, it is for the sake of their own and their baby's health. There are many examinations that need to be done during pregnancy, each with its own functions and effects. Among them, blood tests are included. However, what are the items of blood tests during pregnancy?
1. HCG blood test
For the accuracy of pregnancy detection, doctors generally recommend performing a blood HCG early pregnancy test. Quantitative testing of HCG values through blood can provide a more sensitive and accurate response to pregnancy than qualitative testing of urine using early pregnancy test strips, with an accuracy rate of over 99%. In addition, for multiple pregnancies, ectopic pregnancies, abnormal embryonic development delay, molar pregnancy, certain endocrine diseases or tumors, combining blood HCG values with clinical conditions and other examination results can often lead to correct judgments through comprehensive analysis. HCG blood test requires fasting.
2. Blood routine examination
It is mainly used to determine whether the pregnant mother has anemia. Mild anemia will not have much impact on the pregnant mother and delivery, but severe anemia may lead to adverse consequences such as premature birth and low birth weight infants.
3. Blood type examination
In early pregnancy, blood tests are usually taken to check blood type, which is beneficial for timely prevention of hemolytic disease of the newborn. The second is to prepare for blood transfusion. Once a pregnant woman experiences early pregnancy miscarriage, ectopic pregnancy, placenta previa, placental abruption, or vaginal bleeding during delivery, it may endanger her life due to excessive blood loss.
4. TORCH inspection
TOUCH examination is commonly referred to as the four types of viruses, including rubella virus, cytomegalovirus, Toxoplasma gondii, and herpes simplex virus. Pregnant women infected with these viruses can cross the placental barrier and infect the fetus, which may cause serious congenital malformations and even miscarriage. So it is best to perform this test during preparation, which is normally negative. If the test is positive, it should be treated before getting pregnant. Accept the examination on an empty stomach.
5. Liver function test
This is mainly to check if the expectant mother has hepatitis or other diseases, as pregnancy can increase the burden on the liver. If the mother's liver function is abnormal, it can lead to a decrease in the ability to handle toxic waste substances, causing poisoning to both the mother and the fetus. Secondly, it cannot produce various proteins required by the body, thereby affecting the function of other organs. Thirdly, due to the production of sufficient coagulation factors, there is a high risk of heavy bleeding during childbirth, which endangers the mother's health. In addition The liver has many other functions that can be abnormal, leading to corresponding lesions. Please note that the examination requires fasting.
6. Down syndrome screening
Down syndrome screening is a test to screen for the possibility of Down syndrome in fetuses. Generally, Down syndrome screening involves taking two milliliters of blood from pregnant women, testing serum levels of alpha fetoprotein, chorionic gonadotropin, and free estriol, and then calculating the risk index of Down syndrome based on the pregnant woman's height, weight, age, and gestational age. The optimal screening time is 15-20 weeks of pregnancy.
7. Screening of diabetes in pregnancy
Pregnancy diabetes refers to the phenomenon of diabetes that does not develop diabetes before pregnancy, but only occurs or is discovered during pregnancy. Gestational diabetes can directly affect fetal development and increase the risk of macrosomia. Gestational diabetes may also increase the probability of fetal abortion, intrauterine growth retardation, malformation, macrosomia, low weight and other diseases, and also easily lead to a variety of neonatal complications, such as bilirubinemia, respiratory distress syndrome, etc. Therefore, at 24-28 weeks of pregnancy, the doctor will recommend diabetes screening during pregnancy. It is best to have a light diet the day before the sugar screening, and avoid eating anything after 8 pm, especially fruits and drinks with high sugar content, to avoid affecting the test results.
The above is the encyclopedia's introduction to the relevant items of blood tests during pregnancy. In short, physical examinations such as B-ultrasound, urine tests, blood tests, etc. are necessary during pregnancy. The purpose of each examination varies and its effect on pregnant women is different. And during pregnancy, multiple blood tests will also be done!
