Background:
A delayed asthma reaction occurring several hours after exposure is difficult to diagnose.
Aims:
To confirm a delayed asthma reaction in five workers following epoxy exposure.
Case Report:
Working conditions with exposure to epoxy encountered at the workplace were reproduced in a challenge chamber. Specific inhalation challenge (SIC) with epoxy was compared to a control challenge. All five cases had delayed a asthma response 6-15 h after epoxy exposure.
Conclusions:
Our study confirms that SIC is a useful tool in diagnosing delayed asthma response.

Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
