Abstract
Aim:
To examine prenatal diagnosis strategies through fetal karyotype analysis for 3117 pregnant women with genetic amniocentesis indications.
Materials & methods:
According to the different indications for amniocentesis, the study was divided into 8 groups. The number of amniocentesis specimens, the number of abnormal karyotypes and the positive rate of each group were analyzed.
Results:
Compared with prenatal serum screening, noninvasive prenatal DNA testing is more accurate and can effectively improve screening efficiency. Multiple prenatal diagnosis indicators (37.349%) were more likely to be detected than single prenatal diagnosis indicators (11.091%).
Conclusion:
None of the screening methods can completely replace amniocentesis, and for pregnant women with genetic indications for amniocentesis, amniocentesis is strongly recommended.
