False positives and negatives are possible in the bronchial challenge test.

A bronchial challenge test is a medical test used to assist in the diagnosis of asthma.

The bronchial challenge test is physically demanding, and the results can be affected by muscular weakness or exhaustion.

Bronchial hyperresponsiveness can be assessed with a bronchial challenge test.

This is accomplished through the bronchial challenge test, or methacholine challenge, in which a subject inhales aerosolized methacholine, leading to bronchoconstriction.

Current medical use describes an asthma-like syndrome in infants that may later be confirmed to be asthmatics when they become old enough to participate in diagnostic tests such as the bronchial challenge test.

Spirometry can also be part of a bronchial challenge test, used to determine bronchial hyperresponsiveness to either rigorous exercise, inhalation of cold/dry air, or with a pharmaceutical agent such as methacholine or histamine.
