title: Solid-phase enzyme immunoassay for anti-mite IgE and IgG antibodies in allergic patients.
abstract: Solid-phase enzyme immunoassays for the measurement of anti-mite IgE and IgG antibodies in the sera of mite-allergic patients were developed. In both assays, microtiter plates coated with the crude extract of Dermatophagoides farinae were used. The solid-phase enzyme immunoassay detected mite-specific IgE and IgG antibodies in sera of 18 and 15 out of 20 allergic patients, respectively. The correlation coefficient between the two antibody titers in patients' sera was 0.74, which was statistically significant (P less than .01). Both of the assays require no special facilities for radioactive materials and are considered to be useful in practice for the diagnosis of allergy to house dust mites by combining the results of the two assays.
