General Information About the Test
Test Process and Preparation
The test is considered "positive" if there is a significant improvement in the patient's blowing capacity (FEV1 value) after the bronchodilator medication is given. This condition indicates that the narrowing in the airways is temporary (reversible) and generally supports the diagnosis of "Asthma."
If there is no improvement in respiratory capacity despite the administration of medication (irreversible narrowing), this situation mostly points to COPD. However, a definitive diagnosis is evaluated in conjunction with the patient's clinical history.
Yes. To obtain an accurate result, you will generally be asked to stop using your current bronchodilator inhaler (puffer) medications 12 to 24 hours before the test, under the supervision of your physician.
