Non-invasive prenatal testing is a new and exciting procedure for screening pregnancies for common chromosome abnormalities. Fetal genetic material is present in the circulation of pregnant women and analysis of 7-10ml of maternal blood can identify pregnancies at very high risk of having conditions such as Down syndrome (trisomy 21), Edwards syndrome (trisomy 18) and Patau syndrome (trisomy 13).
“verifi® is a non-invasive prenatal test with the lowest test failure rate of any other test in its class” states Professor Caroline Ogilvie, Professor of Cytogenetics and Consultant Scientist at our Genetics Department at Guy's Hospital, London.
“This test is available to pregnant women from 10 weeks gestation, and verifi®’s turn around times are impressive”, says Dr Kathy Mann, Principal Clinical Scientist at our Cytogenetics Laboratory also at Guy’s Hospital.
The verifi® test is performed by Illumina, based in the U.S.; samples are collected by Viapath Genetics Laboratory located in Guy’s Hospital and sent to the U.S. for testing. Clinical interpretation and support is provided by the Viapath Genetics Laboratory.
Although this test is available to all women, those who are older or who have a raised risk following standard Down syndrome screening, are most likely to benefit. For women with pregnancies that show ultrasound anomalies, chorionic villus or amniocentesis testing are more appropriate, as other chromosome abnormalities may be present that are not detected by non-invasive prenatal testing.
Information forms are available for clinics who wish to access this test for their patients. Streck tubes for collecting maternal blood will be provided by Viapath.
