Non-invasive DNA chromosome segment 22 duplication high risk, pregnant women can be further examined by amniocentesis, once the diagnosis of abnormality, usually can not be. Non-invasive DNA chromosome 22 fragment duplication high risk, suggesting fetal chromosomal abnormalities resulting in chromosomal disorders.
