Name one common test performed in clinical chemistry.

Blood glucose testing is a fundamental and commonly performed test in clinical chemistry. This test measures the concentration of glucose in a patient's blood, providing essential information for diagnosing and managing conditions such as diabetes mellitus. The ability to quickly and accurately assess blood glucose levels allows healthcare professionals to evaluate metabolic functions and helps in monitoring the effectiveness of therapeutic interventions.

In contrast, a complete blood count is primarily associated with hematology, as it assesses multiple components of the blood, including red and white blood cells, hemoglobin, and platelets. A liver biopsy involves the removal of liver tissue for examination and is a more invasive procedure used for specific diagnostic purposes related to liver diseases. X-ray imaging is a radiological procedure rather than a laboratory test and is utilized for visualizing internal structures of the body to diagnose various conditions. These distinctions clarify why blood glucose testing is categorized under clinical chemistry, focusing on the biochemical analysis of bodily fluids.
