The term "lab tests" refers to a series of medical diagnostic procedures conducted in a laboratory setting. These tests are used by healthcare professionals to evaluate and diagnose various conditions, including diseases or disorders that may not be apparent through physical examination alone. Lab tests can involve analyzing blood samples, urine samples, tissue biopsies, or other bodily fluids or tissues to detect the presence of specific substances or abnormalities indicative of a particular condition. The results of these tests provide valuable information for doctors and patients alike in making informed decisions about treatment options and managing health conditions effectively.
