A **blood test** is a vital medical procedure used to assess overall health and diagnose various conditions. It involves drawing a small sample of blood to analyze components like red and white blood cells, hemoglobin, cholesterol, glucose levels, and organ functions. Blood tests help detect diseases such as diabetes, anemia, infections, and heart disorders at an early stage. They also monitor existing health conditions and evaluate the effectiveness of treatments. Regular blood testing enables timely medical intervention, preventing complications. Simple, quick, and often painless, blood tests play a crucial role in maintaining good health and ensuring early disease detection.
