An audiometry exam tests your ability to hear sounds. Sounds vary, based on their loudness (intensity) and the speed of sound wave vibrations (tone).
Hearing occurs when sound waves stimulate the nerves of the inner ear. The sound then travels along nerve pathways to the brain.
Sound waves can travel to the inner ear through the ear canal, eardrum, and bones of the middle ear (air conduction). They can also pass through the bones around and behind the ear (bone conduction).
An electrocardiogram records the electrical signals in the heart. It’s a common and painless test used to quickly detect heart problems and monitor the heart’s health.
An electrocardiogram ? also called ECG or EKG ? is often done in a health care provider’s office, a clinic or a hospital room. ECG machines are standard equipment in operating rooms and ambulances. Some personal devices, such as smartwatches, offer ECG monitoring. Ask your health care provider if this is an option for you.
A vision screening, also called an eye test, is a brief exam that looks for potential vision problems and eye disorders. Vision screenings are often done by primary care providers as part of a child’s regular checkup. Sometimes screenings are given to children by school nurses.
Vision screening is not used to diagnose vision problems. If a problem is found on a vision screening, your or your child’s provider will refer you to an eye care specialist for diagnosis and treatment. This specialist will do a more thorough eye test. Many vision problems and disorders can be successfully treated with corrective lenses, minor surgery, or other therapies.
This test measures the level of adrenocorticotropic hormone (ACTH) in the blood. ACTH is a hormone made by the pituitary gland, a small gland at the base of the brain. ACTH controls the production of another hormone called cortisol. Cortisol is made by the adrenal glands, two small glands located above the kidneys. Cortisol plays an important role in helping you to:
Respond to stress
Fight infection
Regulate blood sugar
Maintain blood pressure
Regulate metabolism, the process of how your body uses food and energy
Too much or too little cortisol can cause serious health problems.
