Brief Summary:
The purpose of this study is to evaluate the performance of the IONA® test which is a non-invasive prenatal test (NIPT) for Down's syndrome and other chromosomal abnormalities in twin pregnancies, from a maternal blood sample.

Condition or disease Intervention/treatment Phase
Down Syndrome Patau Syndrome Edward's Syndrome Procedure: Blood sample Not Applicable

Detailed Description:
350 low risk and 150 high risk women with twin pregnancies will be recruited to produce a large cohort evaluation the use of the IONA test in twin pregnancies for Downs, Edwards and Patau syndrome. Reserve samples will also be used to further develop the test for other chromosomal abnormalities.
