[Leukocyte index for the assessment of an allergic process].

The authors discuss the diagnostic significance of the blood formula and of indexes derived from the formula, used in clinical practice, for assessing the allergic reaction. The counts of eosinophils and lymphocytes increase in 56-86% of cases in allergic reactions. Analysis of the blood formula enabled the authors derive a new index for detection of allergic reaction: the allergization index (AI).
