Can you be a Tang sieve after four months of pregnancy?

Before answering this question, we must first make it clear that Down's screening is divided into two aspects, on the one hand, early Down's screening, and on the other hand, mid-term Down's screening. Among them, early Tang screening is not particularly common, and middle Tang screening is more common. The examination time is between 15-20 weeks.

The subject's question is whether Down's screening can be done after four months of pregnancy. If you are pregnant for four months, it is 16 weeks, and 16 weeks is between 15-20 weeks, so the answer is yes. Of course, you can do Down's screening, but it depends on whether you have evidence of Down's screening, such as being over 35 years old and having other chromosomal abnormalities.

Down's screening is a kind of chromosome aneuploidy screening, especially 2 1- trisomy, but the examination is not high, only 65%, but the positive rate is very high. With the development of society, it will inevitably be replaced by non-invasive. Good luck with your pregnancy.

Conclusion:

16 weeks is too late for Down's screening. You should do it! ! !

Reason:

Some hospitals 12 weeks for NT examination, 16 weeks for Down's screening.

Some hospitals have 12 weeks NT examination, followed by early Down's screening and mid-term Down's screening.

Physical examination on time according to the requirements of the hospital.

At present, you are four months pregnant, more than 16 weeks. Go to the hospital for Down's screening as soon as possible. Down's screening blood can be tested, and the general result time is 7- 14 days, so it takes 17 weeks 18 weeks after completion. If all the risks are low, you can go home safely. If the risk is critical or high-risk, the doctor will recommend non-invasive dna or amniocentesis, and the results of these two tests will be issued on 14 and 1 month respectively. So you have 20 or even 22 weeks.

Prepare for the worst. If the child is really Down syndrome, of course, the sooner it is screened out and the earlier it is intervened, the better it will be for the pregnant mother to recover.

Therefore, pregnant mothers should have a checkup on time. Go to the hospital for Down's screening.

The best time for examination is 14 weeks to 20 weeks of pregnancy, and four months of pregnancy is just suitable for Tang screening! It is necessary to go to a regular hospital for Down's syndrome as soon as possible to rule out Down's syndrome in the fetus.

It is a common pregnancy examination, so we must pay attention to the gynecological examination of children, because it is an important guarantee to avoid fetal injury. Pregnancy examination also helps to find the physical condition of the fetus as soon as possible and treat the problems in time. For the health of children, we must pay attention to it. You need an empty stomach to do this.

Precautions also require pregnant women to keep enough sleep, go to bed early the day before physical examination, and don't make themselves too tired, so as to facilitate the smooth progress of the examination.

Wish me NT, Tang Sie, all the inspections pass smoothly.

The screening test at the beginning of Tang dynasty is usually between 15 and 20 weeks, and can be done in the fourth month of pregnancy.

The risk of giving birth to a child with Down's syndrome was evaluated by detecting the concentrations of fetal protein A and human chorionic gonadotropin in the blood of pregnant mothers, combined with the age, gestational age and drugs of pregnant mothers. You can make an appointment for four-dimensional color Doppler ultrasound when you go to Tangping. After 22 weeks, you can make an anomaly check. You can go to the hospital for an ordinary prenatal examination on time.

Generally, the Tang sieve is examined around 0/5 ~ 20 weeks of pregnancy. The examination is mainly to draw venous blood from the upper limbs of pregnant women to rule out whether the fetus is abnormal.

Generally, Down's screening is in pregnancy 14-2 1 week, so you can do it now.
