Evaluation of a commercial enzyme immunoassay for detection ofMycoplasma pneumoniae specific immunoglobulin G antibodies

A commercial enzyme immunoassay (Platelia Mycoplasma) infections was evaluated and found not to be suitable for the purpose. More than 80 % of healthy persons and patients with non-Mycoplasma pneumoniae respiratory infection, all with a negativeMycoplasma pneumoniae complement fixation test, had a positive EIA. Paired sera did not show the positive correlation between a rise in complement fixation titre and the EIA ratio reported by the manufacturer.
