This book is an English medium (अंग्रेजी माध्यम) title on Practical Clinical Biochemistry, written by Harold Varley, used by MBBS students, postgraduate students in biochemistry and pathology, and medical laboratory technology students. This is the Fourth Edition of a work long regarded as a standard reference on laboratory methods (प्रयोगशाला विधियाँ). Rather than teaching biochemistry as theory, the book documents how each determination is actually carried out: the principle of the method, the reagents required, the step-by-step procedure, the calculation, the sources of error and the normal reference values. It covers the analytical techniques of the clinical laboratory — colorimetry, photometry, flame photometry, chromatography and electrophoresis — along with the estimation of blood glucose, urea, creatinine, uric acid, proteins, lipids, electrolytes, enzymes and hormones, organ function tests, urine and body-fluid analysis, and the interpretation of results (परिणामों की व्याख्या). All content, terminology and explanations in this book are presented in the English language only.
