Book in PDF format The authoritative guide for clinical laboratory immunology. For nearly 50 years, the Manual of Molecular and Clinical Laboratory Immunology has been the premier resource for laboratories, students, and professionals involved in the clinical and technical details of diagnostic immunology testing. The 9th Edition continues its tradition of providing comprehensive clinical and technical information on the latest technologies used in medical and diagnostic immunology. Led by a world-renowned group of authors and editors, this new edition reflects substantial changes aimed at improving and updating the Manual’s utility while reflecting the significant transformations that have occurred since the last edition, including the revolution of gene editing and the widespread adoption of molecularly engineered cellular therapies. Topical highlights include Laboratory Management: three new chapters cover essential aspects of quality assurance, quality improvement, and quality management, aligning with the increasingly stringent and demanding regulatory environment. Inborn Errors of Immunity: the primary immunodeficiency section has been completely updated to align with the latest International Union of Immunological Societies’ classifications of inborn errors of immunity. Functional Cellular Assays: expanded content includes detailed discussions on various functional assays critical for modern immunologic testing. Autoimmune Diseases: expanded chapters on systemic and organ-specific autoimmune disorders, including new chapters on Sjögren’s syndrome and deficiency of ADA2, as well as significant updates on organ-specific autoimmune diseases. Transplantation Immunology: updated chapters detail the assessment of immune reconstitution and ABO testing, reflecting latest practices. The 9th Edition of the Manual of Molecular and Clinical Laboratory Immunology serves as an invaluable resource for laboratory directors, clinicians, laboratory managers, technologists, and students. It provides critical insights into the selection, application, and interpretation of immunologic tests, offering practical guidance on troubleshooting, clinical application, and an understanding of test limitations. This comprehensive and up-to-date manual remains an essential tool for anyone involved in the diagnosis, evaluation, and management of immune-mediated and immune system-related disorders
