Is a negative bronchial test result normal?
A negative bronchial challenge test is normal, and the specific details are as follows:
The bronchial challenge test, also known as a bronchial provocation test, primarily assesses the degree of bronchial narrowing by stimulating the patient's bronchial smooth muscles. It is helpful in diagnosing bronchial asthma. A negative result indicates that the patient’s test outcome is normal, with no apparent abnormalities detected. Prior to undergoing this test, patients should immediately discontinue anticholinergic medications to avoid interference with test results. Additionally, patients should refrain from drinking alcohol or smoking, as these can significantly affect the accuracy of the test. Furthermore, during the procedure, patients should remain relaxed and avoid excessive anxiety. Following the doctor’s instructions and strictly adhering to proper testing procedures ensures accurate results and helps prevent delays in diagnosis.
Although the test results are normal, it is still recommended that patients pay attention to adequate rest in daily life and maintain a balance between work and relaxation. Engaging in appropriate outdoor activities during holidays can help exercise heart and lung function and enhance immunity, which plays a significant role in preventing asthma-related diseases.
