this is a case of occupational asthma which usually diagnosed by spirometry during and after 2 weeks off work ,methacholine challenge test is another method of diagnosing asthma ,The purpose of the inhaled bronchial challenge test using methacholine is to determine how responsive (or irritable) the airways are and to determine the severity of any asthma.

the patient will be asked to inhale a mist that contains different concentrations of methacholine. The mist is produced by a device called a nebulizer and the patient inhales the mist through a mouthpiece. Before the test begins and after each period of inhalation, the patient will be asked to blow forcefully into a spirometer.
