Nucleic Acid Testing for Human Disease describes various techniques including target and signal amplification-based NAT procedures, microarrays, bead-based multiplex assays, in situ hybridization, and SNP techniques. This book discusses RNA expression profiling and laboratory issues such as the need for proper validation of tests intended for routine use. It focuses on specific applications of NATs to human disease diagnosis and treatment, from viral, bacterial, fungal, and protozoan detection to genetic exploration by SNP determinations, patterns of RNA expression, and the growing relevance of epigenetic changes. It also offers different perspectives on future directions in the field.
