[Detection of specific antibodies to all classes, including IgE, against pollen allergens using the ELISA test]. / Prukaz specifických protilátek vsech tríd, vcetne IgE, proti pylovým alergenum testem ELISA.

The authors describe a modification of the immunoenzymatic test suitable for estimation (sensitive dedection) of specific antibodies against pollen allergens of all classes of immunoglobulins, incl. specific IgE. When introducing the method, sera of experimental rabbits immunized with selected allergens were used. After elaboration of suitable conditions, the method was used to assess the presence of specific antibodies in sera of patients with the diagnosis of pollinosis. It was found that the most suitable concentration of pollen allergen combined with the solid phase for detection of specific IgE is 100 micrograms/ml, the optimal concentration of glutaraldehyde used to increase the amount of allergen combined with the solid phase by its polymerization and fixation is 0.25%. The use of the method does not call for special equipment and uses locally produced products. The method is useful for supplementing the diagnosis and its more accurate assessment under clinical conditions when biological tests cannot be used for diagnosis. The test makes monitoring during immunotherapy possible.
