[IgE concentration in healthy children of various age groups].
Serum IgE was estimated in 181 healthy children aged 2 months-17 years. The concentration of IgE was measured by radioimmunosorbent technique (RIST). To eliminate serum interference the IgE levels were calculated using the correction factors: 0,96 and 0,91 (for the sera diluted respectively 1:10 and 1:5). Statistical calculations were made after logarithmic transformation of the particular results. On the base of the mean geometric values linear and parabolic regression lines have been made. On the grounds of the received regression equations it has been found that parabolic variant of the changes of the IgE concentration with respect to age, shows more accurately the real state. The index of the parabolic correlation (r = 0,98) shows a close and positive relations between IgE concentration and the age of children. The lowest concentrations of IgE were found in the youngest group of infants and then the level increased during childhood. The parabolic regression line and 95% confidence limits for the geometric mean values ar inserted in the paper.
