The IONA ® Twin Study
The IONA ® test is a prenatal screening test for Down’s, Edwards’ and Patau’s syndromes. It works by analysing placental DNA which is present in the mother’s blood. Taking part involves a blood test and answering some questions.
Participation is voluntary and you will receive results of the test, which is performed using your donated sample.
In the IONA ® Twin Study, we are assessing how the test, performs in twin pregnancies.
