||A Safer Pre-Natal Diagnosis Using Free DNA in Maternal Blood
Primary Outcome Measures:
Biospecimen Retention: Samples With DNA
Secondary Outcome Measures:
Maternal peripheral blood samples taken in EDTA with that required for existing analysis.
Approx 1ml of fluid from amniocentesis/chorionic villus sampling is taken additional. Patients will be followed up for 1 year after sample taken.

| Estimated Study Completion Date:
It is considered that 20 women with a pregnancy affected by Down's Syndrome (DS), and ~600 normal controls, will be required to be included to ensure sufficient samples for analysis to develop and perfect the diagnostic test. The annual incidence of Down's Syndrome in Oxford is approximately 12/year. The 'pick-up' rate of screening tests is 70-80%. Therefore, 20 true DS cases are likely within the proposed study timescale, making allowances for the cases that will inevitably be missed by screening and non-participation in the study. Patients will be followed up for the period of 1 year.
