%X skin tests require extracts with high quality, which can be measured by determining their allergenic potency using different concentrations of extracts from a manufacturer or comparing extracts from different manufacturers. to compare dust mite extracts produced by manufacturers from spain, argentina, and cuba by using the skin response to the prick test. the prick test was performed on 26 patients aged 2 to 15 years with asthma and rhinitis at the city of camag¨¹ey, cuba, with extracts of dermatophagoides pteronyssinus, d. farinae, d. siboney and blomia tropicalis produced by diater (argentina), alk- abell¨® (spain) y biocen (cuba). among the patients 84.6% attributed the symptoms to changes in weather and house dust. the diameter of the wheal was apparently greater for alk-abell¨®, but no statistical significance was found. the relationship between wheal diameter and log of allergen concentration with biocen products showed a linear dependence in the concentration in the range of 4000 to 100000 ub/ml. prick tests with diameters ??3 mm suggested a greater proportion for alk than for diater and biocen, particularly with d. pteronyssinus and d. farinae, although no statistical significance was found again. dust mite extracts produced and standardized by diater, alk-abell¨® and biocen are similar with respect to allergenic potency.
