Biochemical tests are laboratory procedures used to analyze biological samples, such as blood, urine, or tissue. These tests help identify the presence of specific substances, such as enzymes, hormones, or metabolites, which can indicate health conditions or diseases. Common examples include tests for glucose levels to diagnose diabetes and cholesterol tests to assess heart health. These tests are essential in clinical diagnostics, guiding treatment decisions and monitoring patient progress. They often involve techniques like spectrophotometry or chromatography to measure concentrations of various compounds. Accurate results from biochemical tests are crucial for effective patient care and management.
