[The comparative study of LUMIWARD immunoassay system and CAP RAST system for determination of specific IgE antibody against mite in infantile atopic dermatitis].

We determined the levels of specific IgE antibody against mite in 91 infants with atopic dermatitis by CAP RAST system and LUMIWARD immunoassay system, and observed them for about two years. The correlation between CAP RAST and LUMIWARD was weak. The cut off point was set up at 0.06 IU/ml, most of the patients who had asthma attack or whose atopic dermatitis were poorly controlled during two years judged to be positive. In conclusion, the determination of low levels of specific IgE antibody against mite in infants with atopic dermatitis was reliable to prediction of allergy.
