TEXTBOOK OF CLINICAL CHEMISTRY: Principles, Techniques, and Correlations in Biochemical Testing, Diagnostic Evaluation, Result Interpretation

Clinical chemistry is more than producing numbers-it is the science of determining whether a result is analytically sound, biologically meaningful, and clinically useful. Textbook of Clinical Chemistry is an advanced reference for postgraduate trainees, pathology residents, laboratory scientists, and clinicians who need to understand how laboratory results become actionable information. Organized into seven integrated parts and twenty chapters, the book progresses from measurement foundations to advanced analytical platforms, quality systems, diagnostic reasoning, metabolic systems, organ-based interpretation, endocrine chemistry, and specialty diagnostics. Readers are guided through measurement science, laboratory safety, preanalytical variables, specimen integrity, spectroscopy, electrochemistry, chromatography, mass spectrometry, immunochemistry, automation, informatics, method evaluation, quality control, reference intervals, diagnostic accuracy, Bayesian reasoning, and test stewardship. These principles are applied across proteins, enzymes, carbohydrates, lipids, iron and trace elements, electrolytes, acid-base balance, renal and hepatobiliary function, pancreatic and cardiac biomarkers, endocrine axes, therapeutic drug monitoring, toxicology, oncology, body fluids, pregnancy, newborn screening, ageing, and point-of-care testing. A defining strength is its emphasis on interpretation rather than memorisation. The text connects analytical methods and interferences with specimen quality, biological variation, reference limits, diagnostic performance, and clinical decision-making. Chapters include learning objectives, comparative tables, summaries, and self-assessment questions built around calculations and clinical scenarios. For advanced study, specialist training, laboratory practice, or clinical consultation, this textbook provides a rigorous framework for understanding what a laboratory result says, what it means, and what should happen next.
