Diagnosis ofMycoplasma pneumoniae infection by microparticle aggluination and antibody-capture enzyme-immunoassay

The performance of two new commercial assays for the serological diagnosis ofMycoplasma pneumoniae infection (microparticle agglutination and antibody-capture enzyme-immunoassay) was studied using a panel of 169 serum samples from patients withMycoplasma pneumoniae pneumonia and a control group. Both assays were shown to be sensitive and specific for diagnosis. The performance of the capture immunoassay, however, decreased in older patients, probably due to its inability to detect cases of reinfection without IgM antibody response.
