Human life passes through the following stages, viz. birth, infancy, youth, middle age, and old age or senility, followed by eventual demise. However, each stage has its attendant heath related pitfalls. Study of normal body falls under anatomy and physiology with normal biochemistry, however, all disease states carry with them multiple changes in solid or liquid tissues of the body (blood is also called liquid connective tissue). The study of clinical aspects of disease states is labeled as clinical pathology. Knowing everything about tests without knowing about related clinical pathology is like reading half a book only. This textbook entitled Textbook of Clinical Pathology for MLT Students aims to fulfill that gap in the course study prescribed for students of medical laboratory technology. The book covers all aspects of disease states and related alterations with reasons as to why certain tests are desired either during the disease state or to ascertain recovery. These days we can even forecast future diseases too. It is important to know that we are having a health problem, it is equally important to know that we are absolutely healthy and that no future problems shall ensue.
