One of the tasks that pregnant women must do every month is to go to the hospital for prenatal check ups. The items for prenatal check ups are determined by doctors based on the time of pregnancy and the condition of the pregnant woman. Some prenatal examination items must be completed by pregnant women, while some prenatal examination items can be selectively completed by pregnant women. So, is non-invasive DNA testing a blood draw?
Non invasive DNA testing is a non-invasive examination that involves no wound surface, no risk, and no miscarriage. Non invasive DNA testing is a new technology that involves extracting certain blood samples for testing, which poses no danger to both the mother and the fetus, and is a relatively safe prenatal test.
Overall, non-invasive DNA testing is mainly used to detect chromosomal abnormalities in children, in order to determine whether the fetus has three major chromosomal diseases.
It is suggested that Down syndrome screening can be conducted within 16 to 20 weeks of pregnancy for pregnant women. If the test results are assessed as high-risk, non-invasive DNA testing can be performed.
Non invasive DNA testing is a novel technique for detecting chromosomal disorders in pregnant women. The use of new monitoring technologies and comprehensive bioinformatics solutions can analyze the baby's DNA information contained in the blood of pregnant women, accurately determining whether the baby has various chromosomal diseases such as Down syndrome.
Blood testing can be performed after 12-26 weeks of pregnancy, which is suitable for pregnant women over 35 years old or at high risk.
Based on the following indications, preliminary screening tests for the following high-risk populations can be conducted using non-invasive DNA testing:
1. My mother is over 35 years old.
2. The ultrasound results indicate a high risk of aneuploidy.
3. Trisomy children
4. Early pregnancy, mid-term pregnancy, or three or four screenings showing positive results for aneuploidy.
5. Parents with balanced Robertson translocations are at high risk for fetuses with trisomy 13 or trisomy 21.
