Patient's question:
Female, 32 years old, 5 months pregnant. Last week I had a non-invasive DNA test. Others said that the results of this test can show whether it's a boy or a girl. How can I see if it's a boy or a girl from the non-invasive DNA test results?Doctor's answer:
Non-invasive DNA testing primarily involves collecting a pregnant woman's venous blood, extracting fetal free DNA from it, and using gene sequencing technology to carefully check the baby's gender. If the fetal sex chromosomes are XX, it is a girl; if they are XY, it is a boy. Therefore, non-invasive DNA testing can determine the gender, with an accuracy rate of over 90%. Since the test result screenshot you purchased appears extremely unclear after being magnified, it is difficult to see the specific content of the test results, making it hard to determine whether the test data is normal.
