What is the purpose of this test?
The Theophylline Blood Test is a medical diagnostic test that measures the concentration of theophylline in a patient's blood. Theophylline is a medication used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). The test is typically ordered by a doctor to monitor the patient's theophylline therapy and ensure that the drug is being administered at a safe and effective dose. It may also be used to identify potential side effects of the medication and to adjust the dosage as needed.
The test involves drawing a small amount of blood from the patient's arm and analyzing it in a laboratory. Results are usually available within a few days and are reported as a numerical value indicating the concentration of theophylline in the blood. It is important for patients to follow their doctor's instructions regarding the timing of the test and any necessary preparation, such as fasting or avoiding certain medications. The Theophylline Blood Test is an important tool for doctors in managing respiratory conditions and ensuring the safety and effectiveness of theophylline therapy.
