This is the thoroughly revised and updated edition of the book incorporating most of the recent advances concerned with medical laboratory technology. The new additions in this edition feature the following topics: Laboratory Diagnosis of HIV/AIDS HIV Rapid Text Procedure Coronavirus Infection Dengue Angcard COVID Antigen Test Monkeypox Virus Cephaloplastin Reagent (Liquicelin-E) for Partial Thromboplastin Time (APTT) Monitoring Oral Anticoagulant Therapy using ISI and INR Diagnostics play a prominent role in the field of medicine. Without proper diagnosis, proper conclusion regarding medical treatment and surgery cannot be advised. Appropriate clinical laboratory is set up to carry out medical laboratory technical work in various departments in hospitals and medical institutions. Similarly preparation of reagents of purest quality is also essential. Textbook of Medical Laboratory Technology is designed to train manpower. The students undergoing training of medical laboratory technology learn the techniques of collection of samples, their processing and diagnosis, identification of various fungal infections and diagnosis of microbial infections by serological methods. In addition, students are given training in the use of safety measures while handling infected materials. This textbook has several new dimensions of clinical biochemistry. It presents the measurement of various constituents of blood and other biological fluids and comprehensive coverage of principles and procedures. This book aims to enable the students to carry out routine clinical laboratory investigations (blood, urine, CSF, biopsies and other fluids). Student should be able to provide technical help for selected sophisticated haematological techniques with adequate knowledge of various principles. Advances in diagnostic methodologies and instrumentation have been included.
