Clinical pathology is a specialization in medicine, concerned with the laboratory analysis of bodily fluids such as urine and blood, as well as the examination of tissue samples using cultures and automated analyzers to make a diagnosis of diseases. The analysis of such samples is done at macroscopic and microscopic levels. Immunofluorescence, immunocytochemistry, FISH and cytochemistry are also used to aid in the diagnosis. The secondary specialties of clinical pathology include hematopathology, clinical microbiology, chemical pathology, molecular genetics pathology, cytogenetics, etc. There is an evident overlap between clinical pathology and anatomic pathology, which has led to its expansion to molecular diagnostics and proteomics. This book covers in detail some existing theories and innovative concepts revolving around clinical pathology. The various specializations of clinical pathology, along with technological progress that have future implications, are glanced at in this book. With state-of-the-art inputs by acclaimed experts of this field, this book targets students and professionals.
