Blood analysis, also known as blood testing or blood screening, is a common medical procedure used to assess a person's overall health and detect various diseases or conditions. It involves analyzing a sample of a person's blood to measure levels of certain substances, such as glucose, cholesterol, hormones, enzymes, and blood cells. Blood analysis can help diagnose conditions such as diabetes, high cholesterol, anemia, infections, autoimmune disorders, and cancer. It can also be used to monitor treatment progress, assess organ function, and screen for potential health problems. There are several types of blood tests, including complete blood count (CBC), blood chemistry tests, blood glucose tests, lipid panel, and blood clotting tests, among others. These tests provide valuable information to healthcare providers in making accurate diagnoses and developing appropriate treatment plans for patients.
