What is the accuracy of acetylene uridylic acid?

Many expectant mothers want to know whether the baby is a boy or a girl when they are pregnant. In the past, many older generations made conclusions based on their own personal experience. Now, with the development of high technology, people have realized this wish. Can you know the baby's gender early through some scientific methods? Today we have to talk about acetylene uridine monophosphate, but many people are still concerned about the accuracy of acetylene uridine monophosphate. Let's take a look at the detailed introduction below.

Acetylene uridine acid detection reagent can be used to test the gender, usually around 6 weeks of pregnancy, but the accuracy of this method does need to be considered, and the results are only for personal reference and generally cannot give a 100% accurate answer. Generally, you need to wait for 2 minutes to see the result. If it turns blue after that, it will not be accurate. Generally speaking, this method of testing men and women is unreliable.

Fetal sex determination method

In fact, there are many ways to assess the sex of the fetus. You can just go to the hospital for a B-ultrasound examination. In addition, if you want to know the sex of the fetus, you can also do DNA blood tests, hair follicle puncture biopsy, amniocentesis, etc. So let's follow Baidu Encyclopedia to take a look.

1. B-ultrasound examination

At this stage, B-ultrasound is a very accurate way to distinguish whether a baby is a boy or a girl. Although the gender of the baby can be detected at around 18 weeks of pregnancy, during B-ultrasound, the baby may be facing in the wrong direction or with legs crossed, making it impossible to see the position of his or her genitals. B-ultrasound assessment of fetal gender requires that the pregnant woman be more than 19 weeks pregnant. However, even the most experienced imaging diagnosis can only tell the baby's gender when the pregnancy is about three and a half months or more than three months. The accuracy cannot reach 100%, but the safety factor is the highest.

2. DNA blood test

DNA blood test is also called maternal blood assessment. The technology of genetic engineering can be used to use the blood of the pregnant mother's vein to determine the gender of the fetus. There is no risk to the fetus and pregnant mother. According to the report from the blood DNA test laboratory, the accuracy of the current assessment can reach up to 98%. Gender inference can be made based on sex chromosomes, especially for boys, with a strong positive response. The baby will be examined after 8 weeks and the results will be available in about 3 days. More importantly, this method will not cause any impact on pregnant women and fetuses.

3. Amniocentesis

Amniocentesis is a test that involves extracting a sample of the amniotic fluid of a pregnant woman, usually around 18-20 weeks of pregnancy, and then analyzing the baby's cells. Generally speaking, this method is only performed when the possibility of the baby being deformed is increased, and usually only when the baby is at risk of serious genetic problems will it be used to determine the gender of the fetus. Although the accuracy and safety of the diagnosis have been recognized by the medical community, there are still risks.

4. Villus puncture biopsy

Pregnant women can undergo a CSF biopsy at 10-12 weeks of pregnancy. CSF biopsy is usually performed when the baby may have serious gender-related problems, such as chromosomal abnormalities such as Down syndrome. This CSF biopsy is used to identify the gender of the fetus. Although the use of Vaginal Sampling can determine the gender of the fetus around 10 weeks of pregnancy, it may lead to miscarriage.

5. Ultrasonic Scanner

Ultrasound is a sound wave frequency and has no adverse effects on the fetus, but this method must be tested within 3-4 months of the baby, so that the results will be more accurate. However, when using ultrasound to diagnose the sex of a fetus, the accuracy of confirming a boy is over 95%, while the reliability of confirming a girl is only about 85%.
