Diagnostic instruments are tools used by healthcare professionals to identify and assess medical conditions. These instruments can range from simple devices, like thermometers and stethoscopes, to more complex machines, such as MRI and CT scanners. They help in gathering important information about a patient's health, enabling accurate diagnosis and treatment planning. In addition to traditional tools, diagnostic instruments also include laboratory tests that analyze blood, urine, and other samples. These tests provide critical data about a patient's condition, helping doctors make informed decisions. Overall, diagnostic instruments play a vital role in modern medicine, enhancing patient care and outcomes.
