Prenatal Diagnosis & Reproductive Medicine

Project leads: Stephanie Allen, Dom McMullan, Elizabeth Young, Sue Hamilton - stephanie.allen13@nhs.net

West Midlands Regional Genetics Laboratory is a leading centre in the development and implementation of new Prenatal Diagnostic testing within the UK NHS.   

This includes the development of “non-invasive prenatal testing” for pregnancies at risk of either a chromosome abnormality or a monogenic disorder, and also development and evaluation of the new rapid fetal exome service. 

We work closely with clinical colleagues in Fetal Medicine, Clinical Genetics, Obstetrics and Gynaecology.
