Conditions

Aneuploidy, NIPT

Brief summary

A diagnostic peripheral maternal blood test taken and the free foetal DNA is analysed and the presence of trisomies using a novel method.

Detailed description

A total of \ 2000 participants have donated blood samples used for the development and validation of the IONA non-invasive prenatal screening test for Downs, Edwards and Patau syndrome. The IONA Test was CE marked Feb 2013. We are now recruiting a further 800 participants to provide blood samples to further develop and verify the test for other chromosomal abnormalities and to improve test efficiency.

Design outcomes

Primary

MeasureTime frameDescription
Validation of method of novel analysis for Aneuploidy2013 ApproxAnalysis of maternal blood by a selective amplification of fetal DNA over maternal DNA within that sample. Patients to be followed up for 1 year.

Secondary

MeasureTime frameDescription
Optimization of existing methods for maximising ffDNAup to July 2019Use 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.
