Non-invasive prenatal testing (NIPT) is a relatively recent prenatal screening test that is rapidly being incorporated into clinical practice. All laboratories report a small percentage of samples as “no results” due to low fetal fraction, assay failure, or failed quality control metrics. There is emerging data demonstrating an increased risk of fetal chromosome abnormalities in patients who receive no results. The American College of Obstetricians and Gynecologists (ACOG) recently recommended women who receive no results for NIPT be offered comprehensive ultrasound evaluation and diagnostic testing. However, there is currently no broad consensus on clinical practice recommendations for these cases. The goal of this study was to determine what information women receive from their health care providers about failed NIPT results, how well they understand this information, and how they use this information to make decisions regarding follow-up testing. This study surveyed Kaiser Permanente women who received failed NIPT results. The study found that the majority were not aware of the possibility of a failed result, failed results caused significant anxiety, women who received more of their providers’ time were more satisfied, and participants were not satisfied when results were disclosed indirectly or by someone unqualified to provide further information. The results of this study may help determine how health care providers can best inform their patients who receive failed NIPT results so that the information is understood and used appropriately to make follow-up decisions.

Several lines of evidence indicate that foetal cells - lymphocytes, nucleated red cells, trophoblasts - exist in maternal blood during pregnancy. The potential thus exists for recovering foetal cells from maternal blood and then analysing these cells for foetal genetic abnormalities. This volume explores the biology and maternal foetal transfer of the three cell types during pregnancy, the use of flow cytometry and other techniques to enrich the yield of these cells from maternal blood, the application of diagnostic techniques for identifying cytogenetic and other genetic abnormalities, and public health and other issues involved in the implementation of such testing.

​The recent advances in genomics are continuing to reshape our approach to diagnostics, prognostics and therapeutics in oncologic and other disorders. A paradigm shift in pharmacogenomics and in the diagnosis of genetic inherited diseases and infectious diseases is unfolding as the result of implementation of next generation genomic technologies. With rapidly growing knowledge and applications driving this revolution, along with significant technologic and cost changes, genomic approaches are becoming the primary methods in many laboratories and for many diseases. As a result, a plethora of clinical genomic applications have been implemented in diagnostic pathology laboratories, and the applications and demands continue to evolve rapidly. This has created a tremendous need for a comprehensive resource on genomic applications in clinical and anatomic pathology. We believe that our current textbook provides such a resource to practicing molecular pathologists, hematopathologists and other subspecialized pathologists, general pathologists, pathology and other trainees, oncologists, geneticists and a growing spectrum of other clinicians. With periodic updates and a sufficiently rapid time from submission to publication, this textbook will be the resource of choice for many professionals and teaching programs. Its focus on genomics parallels the evolution of these technologies as primary methods in the clinical lab. The rapid evolution of genomics and its applications in medicine necessitates the (frequent) updating of this publication. This text will provide a state-of-the art review of the scientific principles underlying next generation genomic technologies and the required bioinformatics approaches to analyses of the daunting amount of data generated by current and emerging genomic technologies. Implementation roadmaps for various clinical assays such as single gene, gene panels, whole exome and whole genome assays will be discussed together with issues related to reporting and the pathologist’s role in interpretation and clinical integration of genomic tests results. Genomic applications for site-specific solid tumors and hematologic neoplasms will be detailed. Genomic applications in pharmacogenomics, inherited genetic diseases and infectious diseases will also be discussed. The latest iteration of practice recommendations or guidelines in genomic testing put forth by stakeholder professional organizations such as the College of American Pathology and the Association for Molecular Pathology, will be discussed as well as regulatory issues and laboratory accreditation related to genomic testing. All chapters will be written by experts in their fields and will include the most up to date scientific and clinical information.

Raising hopes for disease treatment and prevention, but also the specter of discrimination and "designer genes," genetic testing is potentially one of the most socially explosive developments of our time. This book presents a current assessment of this rapidly evolving field, offering principles for actions and research and recommendations on key issues in genetic testing and screening. Advantages of early genetic knowledge are balanced with issues associated with such knowledge: availability of treatment, privacy and discrimination, personal decision-making, public health objectives, cost, and more. Among the important issues covered: Quality control in genetic testing. Appropriate roles for public agencies, private health practitioners, and laboratories. Value-neutral education and counseling for persons considering testing. Use of test results in insurance, employment, and other settings.
