DNA gynecological examination

Pregnancy check-ups are necessary during pregnancy. Although there are many items in the prenatal check-up, for the well-being of the fetus and the mother, pregnant women must complete every check-up. The DNA test is an advanced test item that has just appeared in the past two years. It can check whether the fetus has certain diseases. So, what does DNA check for?

DNA testing is also called minimally invasive genetic testing. It determines whether the fetus has sex chromosome abnormalities by examining the fetal DNA fragments in the pregnant woman's blood. This type of DNA test is safer and more sensitive than regular Down syndrome screening, and its accuracy is also very high, without the risk of miscarriage.

However, DNA testing technology has limitations, so currently only the following three most common sex chromosome diseases can be detected:

1. DNA testing can detect Down syndrome. If the fetus has Down syndrome, he or she will have intellectual disabilities and developmental delay after birth. The success rate of the test is 99%.

2. DNA testing can diagnose Edwards syndrome. If the fetus is diagnosed with Edwards syndrome, there will be growth retardation after birth, and most patients will die. The success rate of the test is 96.8%.

3. DNA testing can detect Patau syndrome. If the fetus is suffering from Patau syndrome, it will have intellectual disabilities and unusual appearance after birth. In severe cases, it may cause death. The success rate of the test is 92.1%.

After becoming pregnant, the mother will feel excited and nervous. Every time she goes to the hospital for a prenatal checkup, she will feel nervous inside, fearing that the child will show some abnormality. Generally, a DNA test is required after pregnancy. So, how much does the DNA test cost?

The prices for DNA identification using different methods are also different. If it is used in judicial methods and has legal benefits, it is generally more effective and costs about one thousand yuan. If it were not for these reasons, the prices would vary depending on the testing methods. Some blood samples may cost several hundred yuan, and others are more difficult to test for more than a thousand yuan.
