A Safer Pre-Natal Diagnosis Using Free DNA in Maternal Blood (IONA)
|Official Title:||A Safer Pre-Natal Diagnosis Using Free DNA in Maternal Blood|
- Validation of method of novel analysis for Aneuploidy [ Time Frame: 2013 Approx ]Analysis of maternal blood by a selective amplification of fetal DNA over maternal DNA within that sample. Patients to be followed up for 1 year.
- Optimization of existing methods for maximising ffDNA [ Time Frame: up to July 2019 ]Use of novel methods either in conjugation with existing methods or as a substitute for steps in existing methodologies- currently undergoing laboratory development that could increase the titre of fetal DNA within a given sample. Patients will be followed up for 1 year.
Biospecimen Retention: Samples With DNA
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.
