Allergy diagnosis was based on clinical history and SPT. The determination of specific IgE was performed by ELISA \u2010 RIDASCREEN<jats:sup>R<\/jats:sup>.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> There were no significant differences between the patient's results from Basotest and FastImmune (<jats:italic>P<\/jats:italic>\u2003&gt;\u20030.05). A significant correlation between values, analyzed by Basotest and by FastImmune was found (<jats:italic>r<\/jats:italic>\u2003=\u20030.88). The sensitivity and specificity of the Basotest, FastImmune, specific IgE and SPT were 85%, 72%, 92% and 92% sensitivity and 100%, 92%, 100% and 85% specificity respectively. The efficiency was between 82% and 97%. There were a significant correlation between the specific IgE and flow cytometry tests: tau\u2003=\u20030.92 (Basotest) and tau\u2003=\u20030.71 (FastImmune) and a moderate significant correlation between the SPT and the <jats:italic>in vitro<\/jats:italic> tests: tau\u2003=\u20030.26 (Basotest) and tau\u2003=\u20030.31 (FastImmune).<\/jats:p><jats:p><jats:bold>Conclusion:\u2002<\/jats:bold> The successful use of the Bulgarian grass pollen allergen B1 and both flow cytometry tests was presented.
