Amniocentesis vs chorionic villous sampling as a diagnostic test after an abnormal noninvasive prenatal testing result

Amniocentesis and chorionic villus sampling for prenatal diagnosis.

BACKGROUND A major disadvantage of second trimester amniocentesis is that the result is usually available only after 18 weeks' gestation. Chorionic villus sampling (CVS) and early amniocentesis can be done between 9 and 14 weeks and offer an earlier alternative. OBJECTIVES The objective was to assess comparative safety and accuracy of second trimester amniocentesis, early amniocentesis, trans...

Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 1118, 43 pp. Uppsala. ISBN 91554-5225-6. Amniocentesis (AC) and chorionic villus sampling (CVS) are the principal methods for fetal karyotyping. The aim of this thesis was to evaluate...

A cost-effectiveness analysis of amniocentesis and chorionic villus sampling for prenatal genetic testing.

Amniocentesis and chorionic villus sampling are tests for the prenatal diagnosis of cytogenetic abnormalities. We calculated the incremental costs per abnormal birth averted, and the incremental costs per quality-adjusted outcome, of amniocentesis and chorionic villus sampling performed for the indication of maternal age. Probabilities were obtained from the literature, and direct medical costs...

Prenatal diagnosis of beta-thalassaemia by chorionic villous sampling.

OBJECTIVE To establish intrauterine diagnosis of thalassaemia major in couples with thalassaemia trait by chorionic villous sampling. METHODS A total of 60 couples with children suffering from transfusion dependent beta-thalassaemia or couples who were known carriers of beta-thalassaemia were included in this study. The standard procedure was followed for the collection of samples which was f...
