A medical lab is a facility where tests are conducted on clinical specimens to obtain information about a patient's health. These tests help diagnose diseases, monitor health conditions, and guide treatment decisions. Common types of tests include blood tests, urine tests, and tissue biopsies. Medical labs are equipped with specialized instruments and technology to ensure accurate results. Trained professionals, such as medical technologists and laboratory technicians, perform the tests and analyze the data. The results are then reported to physicians, who use the information to provide appropriate care for their patients.
