Chorionic villus sampling is a prenatal diagnostic test performed for prenatal genetic testing involving a biopsy of placental tissue between 10 to 13 weeks gestation. The tissue harvested is the ...

Research into a simple, accurate and low risk blood test that can detect fetal blood group, sex, and genetic conditions in unborn babies, report scientists. The new, simple and safe DNA blood test ...

A new blood test for Down's syndrome during pregnancy could reduce the number of women who undergo further invasive testing to detect fetal abnormalities, new research suggests. The test — which looks ...

The blood test could mean that 98% of invasive procedures could be avoided, say the authors. The test uses the latest DNA technology to analyse genetic components in the mother's blood that indicate ...

Prenatal testing to detect Down syndrome is carried out with amniocentesis or chorionic villus sampling. Both are invasive tests that carry about a 1% risk of miscarriage. Researchers said Tuesday, ...

Researchers in the Netherlands believe they are on the verge of developing a simple, prenatal blood test that would be able to detect accurately chromosomal abnormalities in the developing fetus. At ...

European researchers have devised a blood test that could help pregnant women avoid the invasive procedures now used to diagnose Down syndrome prenatally and make the diagnosis with 100% accuracy. The ...

Further developments in paternity testing have arisen as a result of the rapidly evolving field of genetic testing technologies. A previous method of determining paternity during pregnancy was to do ...

Three months into her pregnancy, the woman in my office worried that her fetus might have Down syndrome. She wanted a definitive diagnosis, so I referred her to a doctor who inserted a 3 1/2-inch ...

Genetic services in the UK have developed over many years to a highly integrated network of diagnostic testing and clinical counselling. The services have been organised and funded on a regional basis ...
