Medical testing refers to a variety of procedures used to diagnose, monitor, or screen for health conditions. These tests can include blood tests, imaging studies like X-rays or MRIs, and biopsies. They help healthcare providers gather important information about a patient's health and guide treatment decisions. The results of medical tests can indicate the presence of diseases, assess the effectiveness of treatments, or identify risk factors for certain conditions. Common tests include cholesterol tests, glucose tests, and COVID-19 tests. Accurate testing is crucial for effective patient care and improving health outcomes.
