This textbook provides an excellent resource for medical students, physicians in training, clinical chemists, and natural scientists preparing for examinations in laboratory medicine. It not only conveys foundational knowledge but also emphasizes the practical application of rational and efficient laboratory diagnostics in organ systems and pediatrics.

In the first section, the most important organ and metabolic systems (such as carbohydrate metabolism, kidneys, heart, liver, blood profile, and immune system) are uniformly presented concerning their laboratory diagnostic parameters. At the beginning of each chapter, selected laboratory parameters and associated diseases are listed. Additionally, practical examples of targeted stepwise diagnostics for specific suspected diseases are demonstrated using decision trees.

The second section provides an exam-relevant overview of general and specialized clinical-chemical analysis as well as preanalytics.

This textbook serves as a comprehensive guide for modern laboratory medicine, integrating theoretical knowledge with practical, patient-oriented applications.
