1. Non-invasive DNA test does not require fasting. Hong Kong’s non-invasive DNA prenatal test does not require fasting, just a normal diet.

2. Pay attention to the examination time: Non-invasive DNA prenatal testing can be performed as early as 9 weeks into pregnancy, and the results obtained during this time are the most accurate.

3. Non-invasive DNA testing is not the same as Down’s syndrome screening. Down’s syndrome screening is only one of the non-invasive DNA tests. That is to say, non-invasive DNA testing has a wide range of tests, including Down syndrome, Edwards syndrome, Parkinson’s disease, and Down syndrome.

Testing for chromosomal diseases such as Dow syndrome.

Therefore, when pregnant mothers undergo non-invasive DNA testing, they must complete all examination items to ensure the health of the fetus in all aspects.

4. Try to go to a large hospital for examination. Non-invasive DNA genetic testing technology began to enter clinical practice in 2010. It mainly relies on the fetal cells to penetrate into the maternal blood through the placenta and be destroyed by the maternal immune system, and the fetal DNA will remain.

The accuracy of the test results of Hong Kong Yuan Gene Center is as high as 99.70%.

5. Non-invasive genetic testing is low-risk. Does this mean that there will be no problems for the child?

Non-invasive testing and amniocentesis testing are all tests for chromosomal abnormalities. If the malformation and other problems are caused by developmental abnormalities, they need to be monitored by B-ultrasound during pregnancy. All tests during pregnancy are very important, and one test cannot solve all problems.
