What Are Blood Tests?

Blood tests are laboratory examinations of blood. Blood contains many important components, such as red blood cells, white blood cells, platelets, proteins, hormones, and other substances. By testing these components, doctors can learn about the condition of different organs and systems in the body. Blood tests are useful for diagnosing diseases such as anemia, diabetes, infections, and other health conditions. They can also help doctors monitor a person’s health and check whether a treatment or medicine is working properly.

During a blood test, a healthcare professional cleans the skin and uses a small needle to collect blood, usually from a vein in the arm. The blood is placed in a special tube and sent to a laboratory for examination. The process is usually quick and may cause only slight discomfort.
