What does a pregnant woman's blood test check?

Women need to undergo various examinations during pregnancy to ensure the healthy development of the fetus and pay attention to the physical condition of the pregnant woman. During pregnancy, blood tests are required to check blood routine, blood sugar, and to do HIV and Down syndrome screening, etc. Regular check-ups are required from the beginning of pregnancy to before delivery to prevent abnormalities during fetal development. Blood tests are also required before delivery, and other examination items are combined to determine the mode of delivery.

What does the prenatal blood test mainly check?

There are many blood tests that mothers need to do before giving birth, including hepatitis B, blood sugar, hepatitis C, HIV, toxoplasmosis, coagulation, blood routine, urine, etc. Not much blood is drawn, about 3ML is enough. As for the many items, they must be different items and are all necessary. Doing these tests can detect the disease early, treat it early, and prevent transmission to the fetus.

What does a pregnant woman's blood test check?

Blood routine test: to check for anemia, etc.

Blood type ABO+Rh blood type: In order to prepare for blood transfusion during delivery, it is important for expectant mothers to know their own blood type. If the husband has type A, B or AB blood and the pregnant woman has type O blood, the baby may be incompatible with the ABO blood type and corresponding examinations are needed.

Liver and kidney function: whether you have hepatitis, nephritis and other diseases. During pregnancy, the burden on the liver and kidneys is increased. If the liver and kidney functions are abnormal, pregnancy will make the original disease "worse".

Blood sugar: Screening for diabetes

Hepatitis B two-pair-and-a-half test or hepatitis B six items: Check whether the pregnant woman is infected with the hepatitis B virus. If you are already infected, you will need to be transferred to a specialized infectious disease hospital for delivery.

HIV: Whether infected with AIDS. Mother-to-child transmission is one of the main ways of transmission of AIDS.

Alpha-fetoprotein (AFP): Screening for neurological diseases, such as anencephaly and spina bifida.

Hepatitis C (HCV): Check whether the expectant mother is infected with the hepatitis C virus. The hepatitis C virus can also be transmitted to the fetus through the placenta. If you are already infected, you need to be transferred to a specialized infectious disease hospital for delivery.

Screening for Down syndrome: Every expectant mother should undergo Down syndrome screening at 14-17 weeks, which is a chromosome test. If the result is suspicious or positive, amniocentesis should be performed to confirm whether the fetal chromosomes are normal. For expectant mothers over 35 years old, the risk increases with age, so it is even more necessary to do this examination.

Check for rubella virus (RV), Toxoplasma gondii (TOX), cytomegalovirus (CMV), and herpes simplex virus (HSV): If an expectant mother is infected with the above viruses before 4 months of pregnancy, it may cause serious congenital malformations in the fetus or even miscarriage. A better approach is to have this test done before pregnancy, and if the test is positive, get treatment before becoming pregnant.

In addition, regular prenatal check-ups are required to check weight, blood pressure, fetal heart rate, fetal movement, uterine height, abdominal circumference, etc., as well as B-ultrasound, electrocardiogram, urine routine, etc.

Precautions for pregnant women

In order to understand the development of the fetus and their own physical condition in a timely manner, pregnant women should undergo regular prenatal examinations. Antenatal check-up is a special examination performed on pregnant women by an obstetrician. Starting from early pregnancy, pregnant women should have a check-up once a month. After 28 weeks of pregnancy, check once every 2 weeks; after 36 weeks, check once a week. If any abnormalities are found during the examination, you should see a doctor immediately.
