Description: This test measures the level of theophylline in your blood. Theophylline is a chemical similar to caffeine. It's sometimes used as a medicine to treat lung conditions such as asthma, chronic obstructive pulmonary disease, and bronchiolitis. Sometimes it's prescribed to babies, especially premature infants, to help their breathing and lung function.
Theophylline reduces inflammation or irritation in lungs and airways, relaxes smooth muscles in the airways and digestive system, and stimulates the central nervous system. But theophylline can be harmful in high doses or if the theophylline level in your blood is too high, so your healthcare provider may want to test your level of theophylline.
