This document discusses various health checkup tests that can help detect life-threatening conditions. It describes 2D echocardiography which uses imaging to examine the heart and detect any abnormalities. An electrocardiogram (ECG or EKG) checks the heart's electrical activity and can find symptoms of heart disease. A pulmonary function test evaluates lung health and ability to intake oxygen through spirometry. Other tests discussed include bone density scans, blood pressure checks, mammograms, screening for stroke, Pap smears, PSA tests, lipid profiles, blood glucose tests, and thyroid function tests. Regular checkups can help catch health issues early through these important medical screening tests.
