A routine physical exam measures important vital signs such as temperature, blood pressure, and heart rate. Your doctor will evaluate your body using observation, palpitation, percussion, and auscultation (listening to your heart, lungs with a stethoscope). Imaging studies may include X-rays, computer-tomography (CT), magnetic resonance (MRI) scans, and an electrocardiogram (EKG). Common laboratory tests may include a blood test, a urine specimen, and stool and sputum cultures.
