With more and more attention paid to prenatal examination, the requirements for medical service level are getting higher and higher. It has become a craze to go to Hong Kong for non-invasive DNA prenatal examination. Numerous cases have also verified that the non-invasive DNA testing program in Hong Kong is indeed the only choice for prenatal examination.
Why do pregnant mothers in Hong Kong have to do non-invasive DNA testing?
Because the non-invasive DNA prenatal examination in Hong Kong is a comprehensive screening of 23 pairs of fetal chromosomes, with as many as 95 detection items. When pregnant mothers do this test, pregnant mothers need to be pregnant for more than 10 weeks to test, and the accuracy rate can be as high as 99.5%. Moreover, the occurrence of fetal chromosomal diseases is accidental and random, and the incidence rate increases with the age of pregnant mothers. At present, there is no effective means to treat chromosome diseases. The methods to reduce the risk of chromosomal diseases in children mainly rely on prenatal screening: Down's screening (accuracy 60%-70%), villus sampling, amniocentesis (abortion risk), and finally non-invasive DNA testing.
Hong Kong non-invasive DNA testing project has the advantages of simplicity, safety, rapidity and accuracy by sequencing fetal free DNA in maternal venous blood and analyzing it by bioinformatics. This test item can comprehensively detect whether there are genetic abnormalities in the fetus, including *** 19 items. Triploid syndrome is common, such as Down syndrome (T2 1), Edwards syndrome (T 18), Patau syndrome (T 13) and other sex chromosomes.
What needs to be pointed out here is that research shows that the older a pregnant mother is, the greater the chance of giving birth to a Down's baby, so general doctors will advise pregnant mothers over the age of 35 not to do Tang screening, because most of the test results are high-risk. Therefore, elderly women must do non-invasive DNA testing in Hong Kong.
Compared with traditional detection methods, non-invasive DNA prenatal detection in Hong Kong has obvious advantages. It is a safe and non-invasive detection method with no risk of abortion, wider screening range and more chromosomes. More importantly, its accuracy rate is over 99.5%, which greatly reduces the risk of subsequent trauma caused by false positive results and missed detection in Tang screening. Choosing scientific and safe check-up items can save a lot of unnecessary troubles and greatly relieve the mental stress of pregnant mothers, so that the baby can develop better.
