Such tests show a sensitivity of about 99% and a specificity of more than 99.9%. Therefore, they cannot be regarded as diagnostic procedures but may be used to confirm a positive maternal screening test such as a first trimester screening or ultrasound markers of the condition. [61] [62] Trisomy 13 and 18
The test operates by sampling cell-free DNA in the mother's blood, which contains some DNA from the fetus. The proportions of DNA from sequences from chromosome 21, 18, or 13 can indicate whether the fetus has trisomy in that chromosome. In a randomized controlled trial of 1,696 pregnancies at high risk for Down syndrome, the test correctly ...
In 2014, Bianchi was the lead author on a study published in the New England Journal of Medicine that examined cell-free fetal DNA test performance in a general obstetrical population. This study showed that cell-free DNA testing had lower false positive rates and higher positive predictive values than maternal serum biochemistry analyses with ...
Five sets of unidentified human remains discovered on Oahu, including the victim of an unsolved homicide, are under consideration for a free-of-charge DNA analysis to be conducted by a private ...
Screening tests can then include serum analyte screening or cell-free fetal DNA, and nuchal translucency ultrasound [NT], respectively. [59] It is important to note that screening tests are not diagnostic, and concerning screening results should be followed up with invasive diagnostic testing for a confirmed diagnosis.
