[IgE determination in a group of allergic patients in Cuba]

Because the importance of IgE in allergic phenomena and due to the fact that its measurement is not usual in our country, we decided to evaluate this immunoglobulin in 62 patients suffering one or more allergic symptoms. We used PRIST, the solid phase radioimmunoassay by the sandwich technique. IgE was increased in 75% of the patients. Factors influencing this find were analyzed: geographic, weather and environmental conditions, genetic and other factors.
