Patient's question:
My cousin is pregnant. Since she and her husband are both recent university graduates, they both want to have healthy offspring. They have gone to the hospital for a check-up, and the doctor recommended an NIPT (Non-Invasive Prenatal Testing). I would like to ask how the NIPT test is performed?Doctor's answer:
Hello, non-invasive DNA testing for fetal aneuploidy involves extracting blood from the pregnant woman, identifying fetal cells in the mother's blood, and then examining the chromosomal genes in those fetal cells to check for any abnormalities. Based on the test results, appropriate actions are taken. If the non-invasive DNA test results strongly suggest a chromosomal gene abnormality in the fetus, a final diagnosis is required. This is achieved through amniocentesis or cord blood sampling to accurately detect fetal cells, perform chromosomal testing, and confirm the presence of any abnormalities. Corresponding treatment may then be necessary.
