This document outlines and describes various common clinical laboratory tests performed on blood, urine, feces, and other tissues and fluids to evaluate health and diagnose diseases. It discusses tests in several categories including clinical chemistry tests, hematological tests, liver function tests, kidney function tests, pulmonary function tests, and thyroid function tests. The tests measure levels of proteins, enzymes, hormones, metabolites, and blood counts to screen for and monitor various conditions.
