What's in My Blood Test?

This book is designed to help readers better understand the vital role of blood in maintaining health, with a particular focus on interpreting common blood tests. It explains what blood is composed of—red and white blood cells, platelets, and plasma—and how standard tests such as full blood counts and cholesterol panels provide insight into physiological function and overall well-being. Medical terminology and blood test jargon are clearly defined, and test results are presented in a straightforward, comprehensible manner. In addition to test interpretation, the book explores how various components of blood—such as glucose, fats, lipids, proteins, electrolytes and hormones—reflect internal balance and respond to influences like diet, stress, exercise, and illness. It also offers evidence-based guidance on nutrition, supplements, medications and lifestyle strategies that support healthy blood composition and function. Each chapter is self-contained, allowing readers to navigate directly to topics of personal interest without needing to read the book sequentially. No prior scientific knowledge is assumed; where technical terms are necessary; they are clearly and concisely explained. Although written for a general audience, the book will also be valuable for undergraduate medical and laboratory science students, nursing students, paramedics, allied health professionals, and anyone interested in how blood tests relate to health and disease.
