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.
Spirometry is a type of pulmonary function test, or a lung function test, that measures the flow of air through your lungs. It also estimates the amount of air in your lungs. The test is performed using a machine called a spirometer. It measures the amount of air you breathe and how fast you can blow air out of your lungs. Spirometry is a safe and commonly ordered test.Spirometry tests determine if lungs are functioning at expected levels. It helps to diagnose lung and airway diseases. For example, the test can detect chronic obstructive pulmonary disease (COPD) before symptoms develop. The test can also check for pulmonary fibrosis, or scarring of the lung tissue.
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.
