About Blood test (Procedures)
A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a needle, or via fingerprick. Blood tests are used to determine physiological and biochemical states such as disease, mineral content, drug effectiveness, and organ function.
