Occupational asthma in a laboratory technician

This observation reports the case of an occupational allergic asthma in a laboratory technician, caused by exposure to formaldehyde. She experienced feelings of discomfort during low exposure, below the regulatory exposure thresholds. Sent to occupational medicine, signs of an asthma attack were noted by the doctor. Respiratory function tests showed bronchial hyperactivity. The diagnosis of formaldehyde asthma was made due to the recurrence of signs during exposure and the absence of other allergies. This type of occupational asthma is rare nowly and this case is an opportunity to recall what the different occupational asthmas are and which are the most common among laboratory technicians.
