Prevalence and risk factors for latex allergy
EDITOR
We read with interest the cross sectional
study of latex allergy of workers in a United Kingdom
hospital.1 We have also tried to study healthcare workers
in a district general hospital and have had problems with the response
rate for skin prick testing and also blood taking. We have, however,
used standardised and evaluated skin prick test materials from
Stallergen (1:200) and the Pharmacia CAP for latex and have found a
high percentage of symptomatic workers with positive skin tests and
specific IgE. We also found that workers in general wards were exposed
to as much airborne latex as those in operating theatres, accident and emergency, and intensive care, areas which we previously thought of as
high exposure. Median concentrations of latex in air were 0.44 µg/m3 in our high exposure areas and 0.48 µg/m3 in our lower exposure areas, perhaps because
