  • Title: [Occurrence of allergens on hospital premises].
    Author: Andersen UM, Osterballe O.
    Journal: Ugeskr Laeger; 2000 Jan 24; 162(4):490-2. PubMed ID: 10697446.
    Abstract:
    The occurrence of allergens from the house-dust mites Der p 1, Der f 1 and Der m, and from dogs (Can f 1) and cats (Fel d 1) was assessed in Viborg Hospital. Three hundred samples collected in a standardized manner were analysed for allergens by ELISA technique. In only one dust sample was the total occurrence of mite allergens marginally above the sensitization threshold level of 2,000 ng mite allergens/g dust. For Fel d 1 a threshold level for sensitization or symptoms of 8,000 ng Fel d 1/g dust has been proposed; none of the dust samples contained this concentration. A low occurrence of Can f 1 was found. One dust sample contained 8,902 ng Can f 1, while the remainder exhibited lower concentrations. Efficient cleaning and adequate ventilation can reduce allergens in public buildings, but it is impossible to remove all allergens from upholstered furniture. Avoidance of such furniture in wards and outpatient departments which receive allergic patients might be considered.
