Understanding Fetal Fraction in cfDNA screening

Fetal fraction has been used by some laboratories to determine if they can have confidence in their results. However, there are significant factors to consider when determining its merit, including assay precision, the accuracy of a reported fetal fraction metric and the implications of using a fetal fraction cutoff. In the enclosed publication, we present the science, the data and the impact of using the fetal fraction metric within a clinical context.

Making NIPT accessible to all women

This webinar aims to address some of the obstacles that have prevented the widescale adoption of NIPT. Issues such as: cost, focus, precision and ease of use will all be examined by our speakers and then reevaluated using PerkinElmer's new Vanadis® NIPT platform. Speakers include Prof. Howard Cuckle (Tel Aviv University, Israel) and Dr Alka Chaubey (PerkinElmer Global Genomic, USA)
