The doctor will ask questions about your medical history, current lifestyle behavior, and vaccination status during a physical exam. If you have any complaints or concerns about your health, this is the perfect time to voice them. After checking your vital signs, your doctor will conduct a physical examination. In addition to temperature, blood pressure, and breathing rate, heart rate is also measured. In order to detect heart murmurs, heart diseases, and reduced breathing sounds, doctors use stethoscopes to listen to the heart and lungs. Lab tests may require a blood sample, plasma sample, or urine sample. The tests are used to detect issues with the immune system, organs, and blood chemistry. As well as a thyroid screening, you might need to undergo a diabetes screening. Additional tests and examinations may be ordered as necessary.
