[Value of quantitative IgE measurement].

The results of assay of IgE can only be expressed by a very imprecise system of classes. Quantification of the measurement of IgE by the method of the CAP-system of prognosis of allergic patients. Expression of IgE by a measurement of intensity of fluorescence allows the establishment of a decent curve for each allergen. It makes a method of predictive evaluation of risk of the allergy pathology for each allergen. It significantly improves the sensitivity, since it allows detection of IgE at levels less than 0.35 KUA/l. Thus it gives a considerable improvement for the clinician at the level of diagnosis avoiding the "gold standard" provocation test in allergy diagnosis as well at the level of prognosis.
