Blood tests, also known as blood work or laboratory tests, are crucial diagnostic tools used to assess various aspects of a person’s health. These tests involve the collection and analysis of a blood sample to evaluate factors such as blood cell count, cholesterol levels, glucose levels, liver and kidney function, hormone levels, and markers of infection or inflammation. Blood tests provide valuable information that aids in the diagnosis and monitoring of conditions, as well as guiding treatment decisions. They are performed in medical laboratories by skilled professionals and play a vital role in preventive care, disease management, and overall healthcare assessment.
