First-Trimester Detection of Down Syndrome Using Fetal Ultrasound Markers Combined with Maternal Serum Assessment
ثبت نشده
چکیده
Note: It should be noted that appropriate training of ultrasonographers with ongoing quality assurance programs are considered critical to the accurate measurement of fetal nuchal translucency. In addition, in published studies of first trimester screening, the laboratory and imaging components of screening (i.e., fetal nuchal translucency and measurement of maternal serum factors) are performed in a coordinated fashion.

Non-invasive prenatal diagnosis: improved detection rates.
In the Prenatal Diagnosis special issue of July 2010, a good prediction was made by the author (Dennis Lo, 2010) on non-invasive methods of diagnosis of fetal anomalies. Non-invasive prenatal diagnoses are useful in the detection of fetal genetic abnormalities, aneuploidies and high-risk pregnancy. Fetal DNA analysis in maternal plasma using single molecule analysis method, no doubt, will defin...

The aim of the present study was to evaluate the efficacy of the first trimester screening for Down syndrome (DS) in an unselected low-risk Finnish population. The study involved 4,617 women who attended screening between the 8th and 14th weeks of pregnancy in 1998-2000. They gave a blood sample for the measurement of pregnancy associated plasma protein A (PAPP-A) and free beta human chorionic ...

BACKGROUND The acceptability of prenatal screening and diagnosis of Down syndrome is dependent, in part, on the gestational age at which the testing is offered. First trimester screening could be advantageous if it has sufficient efficacy and can be effectively delivered. ISSUES Two first trimester maternal serum screening markers, pregnancy-associated plasma protein-A (PAPP-A) and free beta-...
