The new edition of this case-based learning tool will enhance your skills in clinical lab test interpretation. It provides fundamentals of interpreting lab test results not only for pharmacy students, but also for practitioners as an aid in assessing patient drug-treatment responses. It is the only text written by and for pharmacists and provides case studies and practical information on patient therapy. New to the fourth edition are: three new chapters including new information on men's health, women's health, and pharmacogenomics and laboratory tests; mini-cases embedded in each chapter that provide therapy-related examples and reinforce important points made in the text; 'Quickview Charts' that give an overview of important clinical information including reference ranges and critical values; and, 'Learning Points' that focus on a clinical application of a major concept present in the chapter.
