What tests are optional during pregnancy?

Pregnancy nutrient analysis, bone density testing and trace element testing do not need to be done and are a waste of money. Now the living conditions are very good, everyone's nutrition is basically very comprehensive, there will be no lack of nutrition, that is, you should pay attention to your diet in the later stage, do not overeat.

Folic acid gene monitoring is not accurate at all, and it is not recommended to do it abroad; Trace element monitoring, the content of trace elements in different parts of the body is different; There is no need to do bone density screening, just supplement calcium on time.

Nutritional analysis during pregnancy, bone density test, trace element test. Now that the living conditions are better, everyone is basically nutritionally balanced, there will be no lack of nutrients, and more attention is paid to diet after pregnancy, so as not to worry about the lack of nutrients in the fetus, but to pay attention to controlling the diet to prevent the fetus from growing too large.

Prenatal check-up is not a panacea, and some dominant genetic problems, such as rabbit lips, can be examined. However, there are some diseases that cannot be detected, such as these 4 kinds, and it is best for pregnant mothers to be aware of them.

As everyone mentioned at the beginning, this mother, although she has done every new prenatal check-up project, the child's hearing problems have not been checked. The hearing of the fetus gradually grows after 4 months of pregnancy, and it is already close to the level of adults by 6 months. However, whether the fetus's hearing is a problem or not cannot be distinguished according to the diagnosis and treatment method at this stage.

Usually after the baby is born, the doctor will test his hearing to check whether there is a hearing impairment.

Some pregnant mothers also have prenatal check-ups on time during pregnancy, but the baby is completely blind after birth. In the early stages of pregnancy, there are several types of examinations that are all deformity examinations, such as major deformity and Tang screening examinations. However, according to the four-dimensional color ultrasound, the doctor can clearly see the facial features and internal organs of the fetus, but he cannot know what the fetus's eyes and vision are.

The fetus is always closed in the womb, and even if it is not closed, it is impossible to distinguish the vision of the fetus with current medical technology.

In the process of prenatal examination, the new project of cardiac ultrasound will also be involved, but this examination will also have a certain one-sidedness. It can only detect whether the fetus has major cardiovascular problems, such as some minor cases or cannot be detected.

Most people are unfamiliar with this disease, its full name is congenital metabolism abnormality, and this kind of disease is difficult to detect according to the prenatal examination. Generally, this kind of disease will also be genetically inherited, if the pregnant mother herself will have such a disease, then the fetus is likely to have abnormal metabolism in the whole process of growth and development in the uterus.

This type of disease can be detected gradually after the birth of the child, depending on the child's diet. If the child has the problem of abnormal metabolism, the main manifestation is that the physical fitness is not very good, and the body size is much smaller than that of people of the same age.

Fetal brain hypoplasia, cerebral palsy, congenital diseases, skeletal hypoplasia, blood diseases or immune system diseases cannot be detected.

These diseases that cannot be detected in the prenatal examination are recessive genetic diseases, cardiac insufficiency, low immunity, low resistance, and obesity syndrome, which are generally not detected.

Down's screening is a blood test to measure the concentration of chorionic gonadotropin, fetal protein A, and free estriol in the serum, combined with the mother's weight, pregnancy time, and age, to determine the risk factors of fetal neural tube defects and congenital syndromes. If the fetus is positive, the fetus is at high risk and further chorionic villus examination or amniocentesis is required. Under normal circumstances, 14 to 20 weeks of pregnancy is the best time to be screened for Down's syndrome.

Four-dimensional color ultrasound is the most advanced color ultrasound equipment at present, which can image the surface and clearly see whether there are malformations in the development of fetal limbs, cleft lip and palate, spina bifida and meningitis, which can be detected and solved in time. Four-dimensional color ultrasound is done at 20-24 weeks of pregnancy, but it needs to be done according to individual circumstances, like belly thickness and height weight. The first antenatal visit should be carried out before 12 weeks of pregnancy, and a maternal health record and handbook should be established.

The items of prenatal care are related to the size of gestational age. In the early stages of pregnancy, ultrasonography of the fetal heart rate and fetal buds is required to rule out ectopic pregnancy and determine normal development of the gestational sac.

Around 12 weeks of pregnancy, it is recommended to check the basic condition of the pregnant woman, such as blood routine, urine routine, liver and kidney function, blood glucose, blood type, infectious disease examination, etc. At this time, the most important thing is fetal ultrasound-NT. At 16 to 20 weeks of gestation, the fetus must be screened for Down disease to rule out chromosomal abnormalities and open neural tube defects.

Screening for fetal abnormalities is mandatory at 20 to 26 weeks of gestation, mainly to check for fetal organ malformations. Understand the fetal position, placenta, umbilical cord, amniotic fluid, etc., and choose the appropriate delivery method. Sugar screening for pregnant women for gestational diabetes mellitus, the examination must be fasting, and needs to be scheduled at 24-28 weeks of pregnancy.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Blood routine, urine routine, virus 8 items, kidney function, color ultrasound deformity, mid-term Down screening, these items are all necessary to do, mid-term Down screening is a very important item, you can understand the healthy development of the fetus. These tests can ensure the physical condition of the pregnancy and help to observe the development of the fetal bud.

B-ultrasound, Down's screening, blood group test, four-dimensional color ultrasound, bone density, and thyroid function test are all done, because in this way, we can understand the specific situation of the pregnant woman and the fetus and prepare for childbirth.

Blood glucose, lipids, and blood count are measured. It is also necessary to monitor the growth of the child, because in this way the safety of the child and the pregnant woman can be guaranteed.

Radiology CT MRI tests should not be done during pregnancy because they are radioactive and can cause fetal development malformations.

The tests that cannot be done during pregnancy are generally MRI CT examinations, because the impact of this type of examination on the pregnant woman's body is very unfavorable, and these are equivalent to some harmful radiation, so try not to do these tests.

One is about the procedure, such as what to do during the prenatal checkup, what to eat, how to control the weight, and what the production process is like;

the second is about various pregnancy discomforts, such as morning sickness, inability to sleep, edema and urine leakage, etc.;

The third is about various health information, such as whether to take DHA and how to prevent stretch marks;

the fourth is about various pseudo-scientific rumors, such as whether you can eat crabs and whether you want to go to fetal poison;

Here are the answers to the above questions, I hope it will be helpful to you.

How many prenatal check-ups should I have at least during pregnancy?

In the first trimester of pregnancy, within 12 weeks of pregnancy, the doctor needs to make a detailed examination of the physical condition of the expectant mother, conduct routine urine and blood tests, as well as liver function, kidney function, syphilis test, etc., these test results are also the evidence of whether the pregnant woman can be successfully filed. The recommended number of prenatal examinations in China is based on the size of the gestational week, which is 6-13+6 weeks, 14-19+6 weeks, 20-24 weeks, 25-28 weeks, 29-32 weeks, 33-36 weeks, and 37-41 weeks.

A reasonable time and frequency of prenatal check-ups can ensure that doctors are always aware of the development of the pregnant mother and the baby in the womb. Therefore, pregnant mothers should have timely and correct prenatal check-ups during pregnancy to avoid omissions and affect the health screening of pregnant women and fetuses.

What prenatal check-ups must be done during pregnancy?

1. Down's screening (Down's screening).

Around 20 weeks of pregnancy, every pregnant woman is screened for Down syndrome at 14-20 weeks. Tang screening is mainly to detect whether the fetus has the possibility of having a Down syndrome by drawing venous blood from pregnant women. If the woman's Tang screening is high-risk, further amniocentesis or chorionic villus testing is indicated.

2. B-ultrasound examination

Ultrasound examination can be said to be a kind of examination often done in the prenatal examination of pregnant women, and generally pregnant women will also do B-ultrasound examination to confirm pregnancy before filing. The significance of each ultrasound examination is different during the prenatal examination. Through ultrasound, the doctor can get a comprehensive understanding of the development of the fetus, such as whether it is an ectopic pregnancy, whether there are malformations, amniotic fluid and placenta, etc.

Therefore, it is recommended that pregnant mothers strictly treat each B-ultrasound examination and have a prenatal examination on time.

3. Deformity examination

Pregnant mothers need to go to the hospital for deformity examination when they are about 22 weeks pregnant, because this prenatal examination item is not mandatory, so many novice mothers will think that there should be no mistake in doing prenatal examination on time, so they choose to ignore the deformity examination.

Under normal circumstances, doctors will recommend expectant mothers to do deformity examination in the second trimester, especially for elderly mothers, doctors will emphasize the importance of deformity examination, so you must not be careless during pregnancy, for the healthy development of the baby, do not ignore the deformity examination.

4. Glucose tolerance test

Generally, pregnant women need to have a glucose test at 24 to 28 weeks of pregnancy to ensure that the mother has diabetes.

Note: The day before the examination, Bao Ma needs to fasting for 12 hours, and blood needs to be drawn on an empty stomach during the glucose tolerance test, and a total of 3 blood draws will be taken. They are to drink sugar water to draw fasting blood to check blood sugar, and after drinking glucose water, blood is drawn once every hour and 2 hours.

6-8 weeks pregnant.

The examination is mainly to go to the hospital to confirm whether it is an intrauterine pregnancy.

12 weeks pregnant. Choose a regular hospital to draw blood on an empty stomach and check and file.

Down screening at 16 weeks' gestation.

20 weeks gestation. Repeat blood and urine tests.

At 24 weeks of pregnancy, sugar screening, four-dimensional color ultrasound, fetal malformation screening.

28 weeks gestation. Patients with abnormal blood sugar should do OGTT.

30 weeks pregnant. Instruct pregnant women to count fetal movements, and guide those with abnormal fetal position to correct fetal position.

After 32 weeks, there are some routine check-ups and fetal heart rate monitoring.

There are many prenatal check-up items during pregnancy, starting from the establishment of the mother-child manual, including blood, urine, stool, to doing B ultrasound, eugenics, Down's screening, thalassemia screening, glucose tolerance, listening to the fetal heartbeat, measuring the uterine high abdominal circumference, to four-dimensional color ultrasound, blood pressure, fetal heart rate monitoring, to the later amniotic fluid placenta assessment and so on.

The first time is in the 8th week of pregnancy, and the main test is whether there is an intrauterine pregnancy and whether there is a fetal heartbeat.

The second time was in the 12th week of pregnancy, and Chant could be understood as an early Tang sieve.

The third time is in the 24th week of pregnancy, commonly known as large deformity, depending on the development of the child.

The fourth is between the 30th and 34th weeks of pregnancy, which is a routine check-up, and the fifth is at the 37th week of pregnancy, which is estimated.

Blood test or urine test or B ultrasound can be done, but B ultrasound requires a fetal heart and fetal bud, which can usually be seen at 6 weeks of pregnancy, so a blood test or urine test is recommended.

Early pregnancy: register and create a card. Fasting laboratory tests: blood and urine routine, blood type, RH factor, biochemistry, coagulation, immunity 25 items, etc.

12-13 weeks gestation: ultrasonography, NT, hematuria.

16-17 weeks of pregnancy: Down syndrome screening (blood draw on an empty stomach before 10 a.m. on Thursday, you need to hang the Tang screening number at the window on the first floor), routine prenatal examination.

20 weeks' gestation: routine check-ups, with fetal echocardiography appointments if necessary.

24 weeks of pregnancy: screening B-ultrasound, glucose tolerance test; After 10 p.m. before the blood draw, no food or water.

1. Dissolve all the glucose sugar powder in 200-300 ml of warm water at home and bring it to the district hospital.

2. Arrive at the hospital before 8 o'clock on an empty stomach, draw blood and keep urine first; After 3-5 minutes, start the timer while drinking the sugar water.

3. Blood draw and urine retention 1 hour after taking sugar water;

4. Stop pumping and retain urine 2 hours after taking sugar water;

5. Reduce activities and do not drink water during the inspection.

28 weeks of pregnancy: pelvic and secretion examination, follow-up blood and urine routine, FFN, etc.

30 weeks of pregnancy: B-ultrasound, routine prenatal examination, start to pay attention to fetal movements, see the "Maternal and Child Health Care Manual" for methods. Fetal heart rate monitoring begins at 32 weeks for high-risk pregnant women.

32 weeks of pregnancy: fasting re-examination of blood and urine; Routine check-ups.

34 weeks of pregnancy: routine check-ups, counting fetal movements, see page 6 of the Maternal and Child Health Handbook.

36 weeks of pregnancy: re-examination of B-ultrasound, fetal heart rate monitoring; Identification of the mode of delivery and culture of secretions are done by the specialist. After that, there will be weekly prenatal check-ups. Fasting re-examination of biochemistry, coagulation 2, hepatitis B 6, and electrocardiogram.

37-40 weeks: Weekly check-ups.

40-41 weeks: Twice a week.

All check-ups during pregnancy are for the safety of the mother and the fetus, and there are about 12-15 check-ups throughout the pregnancy, and different types of pregnant women will have to adjust the frequency of pregnancy tests according to different conditions. If everything is normal, only a basic examination is required, and the doctor is not easy to trick you into doing unnecessary examinations, and it is expected that pregnant mothers will not listen to other people's rumors, delay the examination, and do not pay much attention to the health of themselves and the fetus. Basic check-up During this period of 28-30 weeks, the pregnant mother may develop severe anemia and <>

If the pregnant mother has dizziness in her daily life, she needs to pay attention to check her blood routine examination, try to control her blood volume before the pregnant woman gives birth, and the number of basic examinations after entering the late stage of pregnancy is recommended once every 2 weeks. Pregnant mothers need to pay attention to record their baby's fetal movement, if the baby's fetal movement suddenly increases or decreases, must go to the hospital for examination, there may be fetal umbilical cord around the neck or other emergencies. There are also 22 weeks gradually, <>

It is worth noting that the excellent examination period of ultrasound image (four-dimensional color ultrasound) is 22-28 weeks of pregnancy, during which the fetus is active and the epidermis is relatively plump, which is beneficial to the fetal four-dimensional ultrasound imaging and fetal malformation screening, which is the best stage for deformity. Urinalysis is a necessary test for pregnant women during their prenatal check-up, and this type of test can detect and <>

Go to the urine of a pregnant woman to see if there are blood cells, sugar and white blood cell counts. It is important to test for proteinuria, which is important because it is an important major manifestation of hypertension in pregnancy. Pregnant women must have a comprehensive check-up at the first check-up, which is generally key to check the mother's blood shape, urticaria, kidney function and other viral tests.

Routine blood examination can control the risk of disease within the control range, and ensure the health of the pregnant mother and fetus.
